Powerful Chat System – Lesson 3

Today we continue a series of articles on the creation of powerful chat system. Our third lesson will contain next elements: join form (with html5 validation). A long ago, I have already made similar validation. So you can refresh your memories if you like.

Today I will publish updated sources of our growing project (several files was modified, plus I expanded structure of database slightly). All project is well structured: system classes is in ‘classes’ folder, stylesheets in ‘css’ folder, template files in ‘templates’ folder, and – new folder ‘js’ for javascript files.

Now – download the source files and lets start coding !

Step 1. SQL

I have added new field into table of profiles where we will store its first names. So, please execute next SQL:

ALTER TABLE `cs_profiles` ADD `first_name` varchar(255) NOT NULL default '' AFTER `name`;

Step 2. HTML

I have updated template with login form. As you can see – I have expanded this markup and added join form here:

templates/logout_form.html

<div class="column">
    <h3>Powerful Chat System Demonstration</h3>
    <p>Our chat will contain next features: registration, main chat, profiles with avatars, ranking system, private messaging, custom rooms, moderation / administration and possible something else (in future).</p>
</div>
<div class="column">

    <div class="tabs_container">
        <ul class="tabs">
            <li class="active"><h3>Log In</h3></li>
            <li><h3>Join</h3></li>
        </ul>
    </div>

    <div class="nav_container">
        <form class="login_form" action="index.php" method="post" id="1">
            <label>Username:</label><input type="text" name="username">
            <label>Password:</label><input type="password" name="password">
            <input type="submit" name="Login" value="Login">
        </form>
        <form class="join_form" action="index.php" method="post" id="2" style="display: none;">

            <label>Full name:</label>
            <input type="text" id="username" name="username" placeholder="Your name" maxlength="128" title="Your name" required>

            <label>First name:</label>
            <input type="text" id="firstname" name="firstname" placeholder="Your first name" maxlength="128" title="Your first name">

            <label>Last name:</label>
            <input type="text" id="lastname" name="lastname" placeholder="Your last name" maxlength="128" title="Your last name">

            <label>Email:</label>
            <input type="text" id="email" name="email" placeholder="Your email" maxlength="128" title="Format: *@gmail.com" pattern=".*@gmail\.com" required>

            <label>Password:</label>
            <input type="text" id="password" name="password" maxlength="128" title="Password" required>

            <label>Repeat Password:</label>
            <input type="text" id="password" name="password" maxlength="128" title="Repeat password" required oninput="checkpass(this)">

            <input type="submit" name="Join" value="Join">
        </form>
    </div>

</div>

<script>
$(document).ready(function(){
    $('.tabs li h3').click(function () {
      $('.tabs li').removeClass('active');
      $(this).parent().addClass('active');

      $('.nav_container form').hide();
      var index = $('.tabs li h3').index(this);
      $('.nav_container form').eq(index).show();
      return false;
    });
});

function checkpass(input) {
    if (input.value != document.getElementById('password').value) {
        input.setCustomValidity('Password must match.');
    } else {
        input.setCustomValidity('');
    }
}
</script>

Please pay attention to HTML structure of join form, it contain several new attributes for html5 validation: placeholder, required and pattern. This is pretty interesting.

Step 3. CSS

This file has updated too

css/main.css

}

Step 4. PHP

Now, lets review php sources. Our index.php file has updated. I have added here join processing functional. Before actual joining, we have to check if someone else was joined with same email (this field should be unique of course)

index.php

<?php

// set error reporting level
if (version_compare(phpversion(), '5.3.0', '>=') == 1)
  error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);
else
  error_reporting(E_ALL & ~E_NOTICE);

require_once('classes/Services_JSON.php');
require_once('classes/CMySQL.php'); // including service class to work with database
require_once('classes/CLogin.php'); // including service class to work with login processing

$sErrors = '';
// join processing
if (! isset($_SESSION['member_id']) && $_POST['Join'] == 'Join') {
    $sUsername = $GLOBALS['MySQL']->escape($_POST['username']);
    $sFirstname = $GLOBALS['MySQL']->escape($_POST['firstname']);
    $sLastname = $GLOBALS['MySQL']->escape($_POST['lastname']);
    $sEmail = $GLOBALS['MySQL']->escape($_POST['email']);
    $sPassword = $GLOBALS['MySQL']->escape($_POST['password']);

    if ($sUsername && $sEmail && $sPassword) {
        // check if already exist
        $aProfile = $GLOBALS['MySQL']->getRow("SELECT * FROM `cs_profiles` WHERE `email`='{$sEmail}'");
        if ($aProfile['id'] > 0) {
            $sErrors = '<h2>Another profile with same email already exist</h2>';
        } else {
            // generate Salt and Cached password
            $sSalt = 'testing'; // TODO - we will add generation of salt in future
            $sPass = sha1(md5($sPassword) . $sSalt);

            // add new member into database
            $sSQL = "
                INSERT INTO `cs_profiles` SET
                `name` = '{$sUsername}',
                `first_name` = '{$sFirstname}',
                `last_name` = '{$sLastname}',
                `email` = '{$sEmail}',
                `password` = '{$sPass}',
                `salt` = '{$sSalt}',
                `status` = 'active',
                `role` = '1',
                `date_reg` = NOW();
            ";
            $GLOBALS['MySQL']->res($sSQL);

            // autologin
            $GLOBALS['CLogin']->performLogin($sUsername, $sPassword);
        }
    }
}

// login system init and generation code
$sLoginForm = $GLOBALS['CLogin']->getLoginBox();

$sChat = '<h2>You do not have rights to use chat</h2>';
$sInput = '';
if ($_SESSION['member_id'] && $_SESSION['member_status'] == 'active' && $_SESSION['member_role']) {
    require_once('classes/CChat.php'); // including service class to work with chat

    // get last messages
    $sChat = $GLOBALS['MainChat']->getMessages();
    if ($_GET['action'] == 'get_last_messages') { // regular updating of messages in chat
        $oJson = new Services_JSON();
        header('Content-type: application/json');
        echo $oJson->encode(array('messages' => $sChat));
        exit;
    }

    // get input form
    $sInput = $GLOBALS['MainChat']->getInputForm();

    if ($_POST['message']) { // POST-ing of message
        $iRes = $GLOBALS['MainChat']->acceptMessage();

        $oJson = new Services_JSON();
        header('Content-type: application/json');
        echo $oJson->encode(array('result' => $iRes));
        exit;
    }
}

// draw common page
echo strtr(file_get_contents('templates/main_page.html'), array('{form}' => $sLoginForm . $sErrors, '{chat}' => $sChat, '{input}' => $sInput));

As you can see – I have added chat functionality today.

classes/CLogin.php

<?php

class CLogin {

    // constructor
    function CLogin() {
        session_start();
    }

    // get login box function
    function getLoginBox() {
        if (isset($_GET['logout'])) { // logout processing
            if (isset($_SESSION['member_name']) && isset($_SESSION['member_pass']))
                $this->performLogout();
        }

        if ($_POST && $_POST['Login'] == 'Login' && $_POST['username'] && $_POST['password']) { // login processing
            if ($this->checkLogin($_POST['username'], $_POST['password'], false)) { // successful login
                $this->performLogin($_POST['username'], $_POST['password']);
                header( "Location:{$_SERVER['REQUEST_URI']}" );
                exit;
            } else { // wrong login
                return file_get_contents('templates/login_form.html') . '<h2>Username or Password is incorrect</h2>';
            }
        } else { // in case if we already logged (on refresh page):
            if (isset($_SESSION['member_name']) && $_SESSION['member_name'] && $_SESSION['member_pass']) {
                $aReplaces = array(
                    '{name}' => $_SESSION['member_name'],
                    '{status}' => $_SESSION['member_status'],
                    '{role}' => $_SESSION['member_role'],
                );
                return strtr(file_get_contents('templates/logout_form.html'), $aReplaces);
            }

            // otherwise - draw login form
            return file_get_contents('templates/login_form.html');
        }
    }

    // perform login
    function performLogin($sName, $sPass) {
        $this->performLogout();

        // make variables safe
        $sName = $GLOBALS['MySQL']->escape($sName);

        $aProfile = $GLOBALS['MySQL']->getRow("SELECT * FROM `cs_profiles` WHERE `name`='{$sName}'");
        // $sPassEn = $aProfile['password'];
        $iPid = $aProfile['id'];
        $sSalt = $aProfile['salt'];
        $sStatus = $aProfile['status'];
        $sRole = $aProfile['role'];

        $sPass = sha1(md5($sPass) . $sSalt);

        $_SESSION['member_id'] = $iPid;
        $_SESSION['member_name'] = $sName;
        $_SESSION['member_pass'] = $sPass;
        $_SESSION['member_status'] = $sStatus;
        $_SESSION['member_role'] = $sRole;
    }

    // perform logout
    function performLogout() {
        unset($_SESSION['member_id']);
        unset($_SESSION['member_name']);
        unset($_SESSION['member_pass']);
        unset($_SESSION['member_status']);
        unset($_SESSION['member_role']);
    }

    // check login
    function checkLogin($sName, $sPass, $isHash = true) {
        // make variables safe
        $sName = $GLOBALS['MySQL']->escape($sName);
        $sPass = $GLOBALS['MySQL']->escape($sPass);

        $aProfile = $GLOBALS['MySQL']->getRow("SELECT * FROM `cs_profiles` WHERE `name`='{$sName}'");
        $sPassEn = $aProfile['password'];

        if ($sName && $sPass && $sPassEn) {
            if (! $isHash) {
                $sSalt = $aProfile['salt'];
                $sPass = sha1(md5($sPass) . $sSalt);
            }
            return ($sPass == $sPassEn);
        }
        return false;
    }
}

$GLOBALS['CLogin'] = new CLogin();

Minor changes were made in this file too. The rest of the functional was not changed. We will continue enhance our chat soon.

Conclusion

I hope that our new series of articles of chat system creation is useful and interesting for you. If you want to share your ideas, or you noticed any weakness – don’t hesitate to contact us. Good luck and welcome back!

Powerful Chat System – Lesson 2

Today we continue a series of articles on the creation of powerful chat system. Our second lesson will contain next elements: smart chat (ajax, with spam filtering – protection from the frequent messages). I have decided to make registration for next lesson. Hope that it is ok for you.

Today I have included next elements: chat processor, plus – slight corrections in our previous sources. All project is well structured: system classes is in ‘classes’ folder, stylesheets in ‘css’ folder, template files in ‘templates’ folder, and – new folder ‘js’ for javascript files.

Now – download the source files and lets start coding !

Step 1. SQL

This table has got minor changes. I have changed type of field ‘when’.

CREATE TABLE `cs_messages` (
  `id` int(11) unsigned NOT NULL auto_increment,
  `sender` int(11) unsigned NOT NULL,
  `recipient` int(11) unsigned NOT NULL default '0',
  `message` VARCHAR(255) NOT NULL,
  `when` int(11) NOT NULL default '0',
  `room` int(5) unsigned NOT NULL default '0',
  `type` tinyint(1) unsigned NOT NULL default '0',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Step 2. HTML

This is main (index) page html markup:

templates/main_page.html

<!DOCTYPE html>
<html lang="en" >
<head>
    <title>Powerful Chat System - Lesson 2</title>
    <link href="css/main.css" rel="stylesheet" type="text/css" />
    <script src="http://code.jquery.com/jquery-latest.min.js"></script>
</head>
<body>
    <header>
        <h2>Powerful Chat System - Lesson 2</h2>
        <a href="http://www.script-tutorials.com/powerful-chat-system-lesson-2/" class="stuts">Back to original tutorial on <span>Script Tutorials</span></a>
    </header>
    <div class="container">
        {form}
    </div>
    <div class="container">
        <h2>Main Chat Block</h2>
        <div class="chat_messages">
            {chat}
        </div>
        {input}
    </div>
</body>
</html>

As you can see – I have changed our second container (which contains our ajax chat).

templates/login_form.html and templates/logout_form.html

These files haven’t changed since last time. Next one new template – chat form:

templates/chat.html

<form class="chat_submit_form">
    <div><input type="text" name="message" /><input type="submit" value="Submit" name="Submit" /></div>
    <div>
        <h3 class="error">Some error occurs during sending message</h3>
        <h3 class="success">Message successfully sent</h3>
        <h3 class="protect">Please wait 5 secs before adding next message</h3>
    </div>
</form>
<script src="js/chat.js"></script>

Step 3. CSS

This file contains updated styles of our chat

    background-color: #fff;
    margin: 5px;
    padding: 5px;

    -moz-border-radius: 5px;
    -ms-border-radius: 5px;
    -o-border-radius: 5px;
    -webkit-border-radius: 5px;
    border-radius: 5px;
}
.chat_messages .message span {
    color: #444;
    font-size: 10px;
    margin-left: 10px;
}
.chat_submit_form {
    margin: 10px 0px;
}
.chat_submit_form div {
    float: left;
    width: 49%;
}
.chat_submit_form .error, .chat_submit_form .success, .chat_submit_form .protect {
    display: none;
}
.chat_submit_form .error {
    color: #f55;
}
.chat_submit_form .success {
    color: #5f5;
}
.chat_submit_form .protect {
    color: #55f;
}

Step 4. JS

I have created first JS for our chat. At beginning – it contain one function for regular obtaining messages, and handler of form submitting.

js/chat.js

$(function() {
    getMessages = function() {
        $.getJSON('index.php?action=get_last_messages', function(data){
            if (data.messages) {
                $('.chat_messages').html(data.messages);
            }

            // get recent chat messages in loop
            setTimeout(function(){
               getMessages();
            }, 5000);
        });
    }
    getMessages();

    $('.chat_submit_form').submit(function() {
        $.post('index.php', { message: $('.chat_submit_form input[name=message]').val() },
            function(data){
                if (data.result == 1) {
                    $('.chat_submit_form .success').fadeIn('slow', function () {
                        $(this).delay(1000).fadeOut('slow');
                    });
                } else if (data.result == 2) {
                    $('.chat_submit_form .protect').fadeIn('slow', function () {
                        $(this).delay(1000).fadeOut('slow');
                    });
                } else {
                    $('.chat_submit_form .error').fadeIn('slow', function () {
                        $(this).delay(1000).fadeOut('slow');
                    });
                }
            }
        );
        return false;
    });
});

Step 5. PHP

Now, lets review php sources:

index.php

<?php

// set error reporting level
if (version_compare(phpversion(), '5.3.0', '>=') == 1)
  error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);
else
  error_reporting(E_ALL & ~E_NOTICE);

require_once('classes/Services_JSON.php');
require_once('classes/CMySQL.php'); // including service class to work with database
require_once('classes/CLogin.php'); // including service class to work with login processing

// login system init and generation code
$sLoginForm = $GLOBALS['CLogin']->getLoginBox();

$sChat = '<h2>You do not have rights to use chat</h2>';
$sInput = '';
if ($_SESSION['member_id'] && $_SESSION['member_status'] == 'active' && $_SESSION['member_role']) {
    require_once('classes/CChat.php'); // including service class to work with chat

    // get last messages
    $sChat = $GLOBALS['MainChat']->getMessages();
    if ($_GET['action'] == 'get_last_messages') { // regular updating of messages in chat
        $oJson = new Services_JSON();
        header('Content-type: application/json');
        echo $oJson->encode(array('messages' => $sChat));
        exit;
    }

    // get input form
    $sInput = $GLOBALS['MainChat']->getInputForm();

    if ($_POST['message']) { // POST-ing of message
        $iRes = $GLOBALS['MainChat']->acceptMessage();

        $oJson = new Services_JSON();
        header('Content-type: application/json');
        echo $oJson->encode(array('result' => $iRes));
        exit;
    }
}

// draw common page
echo strtr(file_get_contents('templates/main_page.html'), array('{form}' => $sLoginForm, '{chat}' => $sChat, '{input}' => $sInput));

As you can see – I have added chat functionality today.

classes/CLogin.php

<?php

class CLogin {

    // constructor
    function CLogin() {
        session_start();
    }

    // get login box function
    function getLoginBox() {
        if (isset($_GET['logout'])) { // logout processing
            if (isset($_SESSION['member_name']) && isset($_SESSION['member_pass']))
                $this->performLogout();
        }

        if ($_POST && $_POST['username'] && $_POST['password']) { // login processing
            if ($this->checkLogin($_POST['username'], $_POST['password'], false)) { // successful login
                $this->performLogin($_POST['username'], $_POST['password']);
                header( "Location:{$_SERVER['REQUEST_URI']}" );
                exit;
            } else { // wrong login
                return file_get_contents('templates/login_form.html') . '<h2>Username or Password is incorrect</h2>';
            }
        } else { // in case if we already logged (on refresh page):
            if (isset($_SESSION['member_name']) && $_SESSION['member_name'] && $_SESSION['member_pass']) {
                $aReplaces = array(
                    '{name}' => $_SESSION['member_name'],
                    '{status}' => $_SESSION['member_status'],
                    '{role}' => $_SESSION['member_role'],
                );
                return strtr(file_get_contents('templates/logout_form.html'), $aReplaces);
            }

            // otherwise - draw login form
            return file_get_contents('templates/login_form.html');
        }
    }

    // perform login
    function performLogin($sName, $sPass) {
        $this->performLogout();

        // make variables safe
        $sName = $GLOBALS['MySQL']->escape($sName);

        $aProfile = $GLOBALS['MySQL']->getRow("SELECT * FROM `cs_profiles` WHERE `name`='{$sName}'");
        // $sPassEn = $aProfile['password'];
        $iPid = $aProfile['id'];
        $sSalt = $aProfile['salt'];
        $sStatus = $aProfile['status'];
        $sRole = $aProfile['role'];

        $sPass = sha1(md5($sPass) . $sSalt);

        $_SESSION['member_id'] = $iPid;
        $_SESSION['member_name'] = $sName;
        $_SESSION['member_pass'] = $sPass;
        $_SESSION['member_status'] = $sStatus;
        $_SESSION['member_role'] = $sRole;
    }

    // perform logout
    function performLogout() {
        unset($_SESSION['member_id']);
        unset($_SESSION['member_name']);
        unset($_SESSION['member_pass']);
        unset($_SESSION['member_status']);
        unset($_SESSION['member_role']);
    }

    // check login
    function checkLogin($sName, $sPass, $isHash = true) {
        // make variables safe
        $sName = $GLOBALS['MySQL']->escape($sName);
        $sPass = $GLOBALS['MySQL']->escape($sPass);

        $aProfile = $GLOBALS['MySQL']->getRow("SELECT * FROM `cs_profiles` WHERE `name`='{$sName}'");
        $sPassEn = $aProfile['password'];

        if ($sName && $sPass && $sPassEn) {
            if (! $isHash) {
                $sSalt = $aProfile['salt'];
                $sPass = sha1(md5($sPass) . $sSalt);
            }
            return ($sPass == $sPassEn);
        }
        return false;
    }
}

$GLOBALS['CLogin'] = new CLogin();

This class is updated too. I have decided to add ‘member_id’ in sessions too. It will useful afterward.

classes/CMySQL.php

This is database service class. Available in package. Pay attention – database settings of our project is in this file.

classes/Services_JSON.php

This is JSON service class. Available in package.

classes/CChat.php

<?php

class CChat {

    // constructor
    function CChat() {}

    // add to DB message
    function acceptMessage() {
        $sName = $GLOBALS['MySQL']->escape($_SESSION['member_name']);
        $iPid = (int)$_SESSION['member_id'];
        $sMessage = $GLOBALS['MySQL']->escape($_POST['message']);

        if ($iPid && $sName != '' && $sMessage != '') {
            $sSQL = "
                SELECT `id`
                FROM `cs_messages`
                WHERE `sender` = '{$iPid}' AND UNIX_TIMESTAMP( ) - `when` < 5
                LIMIT 1
            ";
            $iLastId = $GLOBALS['MySQL']->getOne($sSQL);
            if ($iLastId) return 2; // as protection from very often messages

            $bRes = $GLOBALS['MySQL']->res("INSERT INTO `cs_messages` SET `sender` = '{$iPid}', `message` = '{$sMessage}', `when` = UNIX_TIMESTAMP()");
            return ($bRes) ? 1 : 3;
        }
    }

    // return input text form
    function getInputForm() {
        return file_get_contents('templates/chat.html');
    }

    // get last 10 messages
    function getMessages() {
        $sSQL = "
            SELECT `a` . * , `cs_profiles`.`name` , UNIX_TIMESTAMP( ) - `a`.`when` AS 'diff'
            FROM `cs_messages` AS `a`
            INNER JOIN `cs_profiles` ON `cs_profiles`.`id` = `a`.`sender`
            ORDER BY `a`.`id` DESC
            LIMIT 10
        ";
        $aMessages = $GLOBALS['MySQL']->getAll($sSQL);
        asort($aMessages);

        // create list of messages
        $sMessages = '';
        foreach ($aMessages as $i => $aMessage) {
            $sExStyles = $sExJS = '';
            $iDiff = (int)$aMessage['diff'];
            if ($iDiff < 7) { // less than 7 seconds
                $sExStyles = 'style="display:none;"';
                $sExJS = "<script> $('#message_{$aMessage['id']}').fadeIn('slow'); </script>";
            }

            $sWhen = date("H:i:s", $aMessage['when']);
            $sMessages .= '<div class="message" id="message_'.$aMessage['id'].'" '.$sExStyles.'><b>' . $aMessage['name'] . ':</b> ' . $aMessage['message'] . '<span>(' . $sWhen . ')</span></div>' . $sExJS;
        }
        return $sMessages;
    }
}

$GLOBALS['MainChat'] = new CChat();

This is our new class for chat processor. For now – it contain only 3 functions: acceptMessage, getInputForm and getMessages.

Conclusion

I will hope that our new series of articles of chat system creation will be useful and interesting for you. If you want to share your ideas, or you noticed any weakness – don’t hesitate to contact us. Good luck and welcome back!

Isometric interactive interior guide

During browsing internet, I have noticed new interesting thing – it looked like isometric guide. Today I will show you how you can create something similar. We will create isometric interactive interior guide with CSS3 and jQuery.

Here are samples and downloadable package:

Live Demo

download in package

Ok, download the example files and lets start coding !

Step 1. HTML

As usual, we start with the HTML. Here is full html code of our guide page. You can see here main scene (container object), six labels on this scene (with some description), and empty dialog element.

index.html

            </div>
        </div>
    </body>
</html>

Step 2. CSS

Now – CSS styles. Which I have separated into two parts: common page styles and styles of our main scene.

css/layout.css

/* page layout styles */
*{
    margin:0;
    padding:0;
}
body {
    background-color:#fefffa;
    color:#fff;
    font:14px/1.3 Arial,sans-serif;
}
header {
    background-color:#212121;
    box-shadow: 0 -1px 2px #111111;
    display:block;
    height:70px;
    position:relative;
    width:100%;
    z-index:100;
}
header h2{
    font-size: 22px;
    font-weight: normal;
    left: 40%;
    margin-left: -300px;
    padding: 22px 0;
    position: absolute;
    width: 1000px;
}
header a.stuts,a.stuts:visited{
    border: none;
    color: #FCFCFC;
    font-size: 14px;
    left: 50%;
    line-height: 31px;
    margin: 23px 0 0 110px;
    position: absolute;
    text-decoration: none;
    top: 0;
}
header .stuts span {
    font-size:22px;
    font-weight:bold;
    margin-left:5px;
}

/* demo */
.container {
    background: url("../images/scene.jpg") no-repeat scroll center top transparent;
    color: #000000;
    height: 535px;
    margin: 20px auto;
    overflow: hidden;
    position: relative;
    width: 1030px;
}
.dialog {
    background-color: rgba(163, 154, 77, 0.9);
    color: #FFFFFF;
    display: none;
    height: 140px;
    left: 343px;
    line-height: 24px;
    padding: 100px 30px;

}
.dialog .close {
    background-color: #65683b;
    cursor: pointer;
    font-size: 22px;
    font-weight: bold;
    height: 36px;
    line-height: 36px;
    position: absolute;
    right: 10px;
    top: 60px;
    width: 36px;

    -moz-border-radius: 18px;
    -ms-border-radius: 18px;
    -o-border-radius: 18px;
    -webkit-border-radius: 18px;

.labels p {
    display: none;
}
.labels a {
    background-color: rgba(203, 189, 58, 0.8);
    color: #FFFFFF;
    display: none;
    height: 50px;
    padding: 30px 0 0;
    position: absolute !important;
    text-align: center;
    text-decoration: none;
    width: 80px;

    -moz-border-radius: 40px;
    -ms-border-radius: 40px;
    -o-border-radius: 40px;
    -webkit-border-radius: 40px;
    border-radius: 40px;
}
.labels > a {
    background-color: rgba(203, 189, 58, 0.8);

    -moz-transition: .3s;
    -ms-transition: .3s;
    -o-transition: .3s;
    -webkit-transition: .3s;
    transition: .3s;
}
.labels a:hover {
    background-color: rgba(128, 128, 128, 0.8);
}
.labels a span {
    border-left: 10px solid transparent;
    border-right: 10px solid transparent;
    border-top: 15px solid rgba(203, 189, 58, 0.8);
    bottom: -14px;
    height: 0;
    left: 30px;
    position: absolute;
    width: 0;

    -moz-transition: .3s;
    -ms-transition: .3s;
    -o-transition: .3s;
    -webkit-transition: .3s;
    transition: .3s;
}
.labels a:hover span {
    border-top: 15px solid rgba(128, 128, 128, 0.8);
}
#label1 {
    left: 720px;
    top: 215px;
}
#label2 {
    left: 495px;
    top: 290px;
}
#label3 {
    left: 450px;
    top: 115px;
}
#label4 {
    left: 270px;
    top: 170px;
}
#label5 {
    left: 570px;
    top: 65px;
}
#label6 {
    left: 275px;
    top: 30px;
}

Step 3. JS

And now – our jQuery code:

js/main.js

jQuery(function(){
    // initialize of labels
    $('.labels a#label1').fadeIn(100).effect('bounce', { times:3 }, 300, function() {
        $('.labels a#label2').fadeIn(100).effect('bounce', { times:3 }, 300, function() {
            $('.labels a#label3').fadeIn(100).effect('bounce', { times:3 }, 300, function() {
                $('.labels a#label4').fadeIn(100).effect('bounce', { times:3 }, 300, function() {
                    $('.labels a#label5').fadeIn(100).effect('bounce', { times:3 }, 300, function() {
                        $('.labels a#label6').fadeIn(100).effect('bounce', { times:3 }, 300);
                    });
                });
            });
        });
    });

    // dialog close
    $('.dialog .close').click(function() {
        $(this).parent().fadeOut(500);
        return false;
    });

    // display dialog on click by labels
    $('.labels a').click(function() {
        $('.dialog p').html( $(this).find('p').html() ).parent().fadeIn(500);
        return false;
    });

    // close dialog on click outside
    $('.container').click(function() {
        $('.dialog').fadeOut(500);
    });
});

Here are just a few event handlers of our scene objects.

Powerful Chat System

Today we begin a series of articles on the creation of powerful chat system. The system will contain next elements: registration, login processing, main chat, profiles with avatars, ranking system (of profiles), private messaging, custom rooms, moderation / administration and possible something else (in future). This will be ajax chat PHP) with storing messages in database (MySQL). Plus we will implement CSS3/HTML5 features in our development process.

Today I have included next elements: initial code (PHP + SQL) with login processor. All project will be well structured: system classes is in ‘classes’ folder, stylesheets in ‘css’ folder, template files in ‘templates’ folder.

Now – download the source files and lets start coding !

Step 1. SQL

Here is SQL structure of tables for profiles and messages

CREATE TABLE `cs_profiles` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `name` varchar(255) NOT NULL default '',
  `last_name` varchar(255) NOT NULL default '',
  `email` varchar(255) NOT NULL default '',
  `password` varchar(40) NOT NULL default '',
  `salt` varchar(10) NOT NULL default '',
  `status` enum('active','passive') NOT NULL default 'active',
  `role` tinyint(4) unsigned NOT NULL default '1',
  `about` varchar(255) NOT NULL,
  `date_reg` datetime NOT NULL default '0000-00-00 00:00:00',
  `rate` float NOT NULL,
  `rate_count` int(11) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8;

INSERT INTO `cs_profiles` (`name`, `last_name`, `email`, `password`, `salt`, `status`, `role`, `about`, `date_reg`, `rate`, `rate_count`) VALUES
('test user', 'test user last name', 'user@user.com', 'b88c654d6c68fc37f4dda1d29935235eea9a845b', 'testing', 'active', 1, 'Few words about test user', '2012-01-14 00:00:00', 0, 0),
('moderator', 'moderator last name', 'moderator@moderator.com', 'b88c654d6c68fc37f4dda1d29935235eea9a845b', 'testing', 'active', 4, 'Few words about moderator', '2012-01-14 00:00:00', 0, 0),
('admin', 'admin last name', 'admin@admin.com', 'b88c654d6c68fc37f4dda1d29935235eea9a845b', 'testing', 'active', 5, 'Few words about admin', '2012-01-14 00:00:00', 0, 0);

CREATE TABLE `cs_messages` (
  `id` int(11) unsigned NOT NULL auto_increment,
  `sender` int(11) unsigned NOT NULL,
  `recipient` int(11) unsigned NOT NULL default '0',
  `message` VARCHAR(255) NOT NULL,
  `when` TIMESTAMP NOT NULL default CURRENT_TIMESTAMP,
  `room` int(5) unsigned NOT NULL default '0',
  `type` tinyint(1) unsigned NOT NULL default '0',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

I have added 3 profiles in the system. Each of them have different role. I plan to make ordinary members (1), moderators (4), administrators (5). You can use another roles (as example 2 and 3) for any other purposes (paid members?). And, quite forgot – password for all of them is ‘password’. So you can login as ‘test user’ -> ‘password’, ‘moderator’ -> ‘password’ and ‘admin’ -> ‘password’. Registration process will in next article.

Step 2. HTML

This is main (index) page html markup:

templates/main_page.html

<!DOCTYPE html>
<html lang="en" >
<head>
    <title>Powerful Chat System</title>
    <link href="css/main.css" rel="stylesheet" type="text/css" />
</head>
<body>
    <header>
        <h2>Powerful Chat System</h2>
        <a href="http://www.script-tutorials.com/powerful-chat-system/" class="stuts">Back to original tutorial on <span>Script Tutorials</span></a>
    </header>
    <div class="container">
        {form}
    </div>
    <div class="container">
        {chat}
    </div>
</body>
</html>

It is easy layout, isn’t it?. Now, next template file for login form:

templates/login_form.html

<div class="column">
    <h3>Powerful Chat System Demonstration</h3>
    <p>Our chat will contain next features: registration, main chat, profiles with avatars, ranking system, private messaging, custom rooms, moderation / administration and possible something else (in future).</p>
</div>
<div class="column">
    <form class="login_form" action="index.php" method="post">
        <h3>Log In</h3>
        <label>Username:</label><input type="text" name="username">
        <label>Password:</label><input type="password" name="password">
        <input type="submit" name="LogIn" value="Login">
    </form>
</div>

Next one template – logout form:

logout_form.html

<div class="column">
    <h3>Hello {name}</h3>
    <h3>Your status:</h3>
    <div>{status}</div>
    <h3>Your role:</h3>
    <div>{role}</div>
</div>
<div class="column">
    <a href="index.php?logout">Log Out</a>
</div>

Step 3. CSS

This file contains styles of our page layout

css/main.css

/* page layout */
*{
    margin:0;
    padding:0;
}
body {
    background-color:#eee;
    color:#fff;
    font:14px/1.3 Arial,sans-serif;
}
header {
    background-color:#212121;
    box-shadow: 0 -1px 2px #111111;
    display:block;
    height:70px;
    position:relative;
    width:100%;
    z-index:100;
}
header h2{
    font-size:22px;
    font-weight:normal;
    left:50%;
    margin-left:-400px;
    padding:22px 0;
    position:absolute;
    width:540px;
}
header a.stuts,a.stuts:visited{
    border:none;
    text-decoration:none;
    color:#fcfcfc;
    font-size:14px;
    left:50%;
    line-height:31px;
    margin:23px 0 0 110px;
    position:absolute;
    top:0;
}
header .stuts span {
    font-size:22px;
    font-weight:bold;
    margin-left:5px;
}

/* main styles */
.container {
    background-color:#222;
    color: #bbb;
    margin: 20px auto;
    overflow: hidden;
    padding:20px;
    position: relative;
    width: 800px;
}
.column {
    float:left;
    width:48%;
}
.column:first-child {
    margin-right:4%;
}
.column > * {
    color:#ddd;
    margin-bottom:10px;
}
.column h3 {
    color:#fff;
}
.login_form input,.login_form label {
    display:block;
    margin-bottom:5px;
}
input[type=text],
input[type=password] {
    width:200px;
}
input[type=submit]{
    height:30px;
    margin-top:10px;
    width:72px;
}

Step 4. PHP

Now, lets review php sources:

index.php

<?php

// set error reporting level
if (version_compare(phpversion(), "5.3.0", ">=") == 1)
  error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);
else
  error_reporting(E_ALL & ~E_NOTICE);

require_once('classes/CMySQL.php'); // including service class to work with database
require_once('classes/CLogin.php'); // including service class to work with login processing

// login system init and generation code
$sLoginForm = $GLOBALS['CLogin']->getLoginBox();

$sChat = ($_SESSION['member_name'] && $_SESSION['member_status'] == 'active') ? '<h2>TODO chat</h2>' : '<h2>You have to login before use chat</h2>';

echo strtr(file_get_contents('templates/main_page.html'), array('{form}' => $sLoginForm, '{chat}' => $sChat));

As we need only login processing for today – our index file is pretty small. New functional will appear in further articles. Here is sources of our login processor:

classes/CLogin.php

<?php

class CLogin {

    // constructor
    function CLogin() {
        session_start();
    }

    // get login box function
    function getLoginBox() {
        if (isset($_GET['logout'])) { // logout processing
            if (isset($_SESSION['member_name']) && isset($_SESSION['member_pass']))
                $this->performLogout();
        }

        if ($_POST && $_POST['username'] && $_POST['password']) { // login processing
            if ($this->checkLogin($_POST['username'], $_POST['password'], false)) { // successful login
                $this->performLogin($_POST['username'], $_POST['password']);
                header( "Location:{$_SERVER['REQUEST_URI']}" );
                exit;
            } else { // wrong login
                return file_get_contents('templates/login_form.html') . '<h2>Username or Password is incorrect</h2>';
            }
        } else { // in case if we already logged (on refresh page):
            if (isset($_SESSION['member_name']) && $_SESSION['member_name'] && $_SESSION['member_pass']) {
                $aReplaces = array(
                    '{name}' => $_SESSION['member_name'],
                    '{status}' => $_SESSION['member_status'],
                    '{role}' => $_SESSION['member_role'],
                );
                return strtr(file_get_contents('templates/logout_form.html'), $aReplaces);
            }

            // otherwise - draw login form
            return file_get_contents('templates/login_form.html');
        }
    }

    // perform login
    function performLogin($sName, $sPass) {
        $this->performLogout();

        // make variables safe
        $sName = $GLOBALS['MySQL']->escape($sName);

        $aProfile = $GLOBALS['MySQL']->getRow("SELECT * FROM `cs_profiles` WHERE `name`='{$sName}'");
        // $sPassEn = $aProfile['password'];
        $sSalt = $aProfile['salt'];
        $sStatus = $aProfile['status'];
        $sRole = $aProfile['role'];

        $sPass = sha1(md5($sPass) . $sSalt);

        $_SESSION['member_name'] = $sName;
        $_SESSION['member_pass'] = $sPass;
        $_SESSION['member_status'] = $sStatus;
        $_SESSION['member_role'] = $sRole;
    }

    // perform logout
    function performLogout() {
        unset($_SESSION['member_name']);
        unset($_SESSION['member_pass']);
        unset($_SESSION['member_status']);
        unset($_SESSION['member_role']);
    }

    // check login
    function checkLogin($sName, $sPass, $isHash = true) {
        // make variables safe
        $sName = $GLOBALS['MySQL']->escape($sName);
        $sPass = $GLOBALS['MySQL']->escape($sPass);

        $aProfile = $GLOBALS['MySQL']->getRow("SELECT * FROM `cs_profiles` WHERE `name`='{$sName}'");
        $sPassEn = $aProfile['password'];

        if ($sName && $sPass && $sPassEn) {
            if (! $isHash) {
                $sSalt = $aProfile['salt'];
                $sPass = sha1(md5($sPass) . $sSalt);
            }
            return ($sPass == $sPassEn);
        }
        return false;
    }
}

$GLOBALS['CLogin'] = new CLogin();

I hope you still remember our previous article of advanced login system. We will have similar system with using sha1 + md5 encryption. All profiles will kept in database.

classes/CMySQL.php

This is database service class. Available in package. Pay attention – database settings of our project is in this file.

Creating photo album with jQuery Fotorama

Today I have prepared tutorial about using new impressive jQuery gallery – Fotorama. This is a nice looking javascript gallery with intuitive controls, and great browser compatibility. You can use this plugin at iPhones and any other mobile devices (you can slide photos with touch).

Here are links to demo and downloadable package:

Live Demo

download in package

Ok, lets download the example files and goto coding !

Step 1. HTML

index.html

This is markup of our result page with Fotorama gallery. Here it is.

<!DOCTYPE html>
<html lang="en" >
    <head>
        <meta charset="utf-8" />
        <title>Creating photo album with jQuery Fotorama | Script Tutorials</title>

        <script src="http://code.jquery.com/jquery-latest.min.js"></script>
        <script src="js/fotorama.js"></script>
        <script src="js/main.js"></script>
    </head>
    <body>
        <header>
            <h2>Creating photo album with jQuery Fotorama</h2>
            <a href="http://www.script-tutorials.com/photo-album-with-jquery-fotorama/" class="stuts">Back to original tutorial on <span>Script Tutorials</span></a>
        </header>
        <div class="container">

            <div id="fotorama">
                <img src="images/pic1.jpg" alt="photo #1" />
                <img src="images/pic2.jpg" alt="photo #2" />
                <img src="images/pic3.jpg" alt="photo #3" />
                <img src="images/pic4.jpg" alt="photo #4" />
                <img src="images/pic5.jpg" alt="photo #5" />
                <img src="images/pic6.jpg" alt="photo #6" />
                <img src="images/pic7.jpg" alt="photo #7" />
                <img src="images/pic8.jpg" alt="photo #8" />
                <img src="images/pic9.jpg" alt="photo #9" />
                <img src="images/pic10.jpg" alt="photo #10" />
                <img src="images/pic11.jpg" alt="photo #11" />
                <img src="images/pic12.jpg" alt="photo #12" />
            </div>

        </div>
    </body>
</html>

Very easy – right?

Step 2. CSS

css/layout.css and css/fotorama.css

First stylesheet is page layout of our page. Second one is default stylesheet file of fotorama gallery. You can customize it (if need). Both files available in our package.

Step 3. JS

js/fotorama.js

This is main gallery javascript file. It uses jQuery, so we have to include both (fotorama.js and jquery) files. This file available in package.

js/main.js

jQuery(function(){
    $('#fotorama').fotorama({
        // width: 1000, // Width of container
        // height: 600, // Height of container
        startImg: 10, // Initial image
        transitionDuration: 400, // Duration of transition
        touchStyle: true, // Enable dragging
        // pseudoClick: true, // Slide between images by click (if touchStyle = true)
        // loop: false, // Loop for images (if touchStyle = false)
        // backgroundColor: null, // Custom background color
        margin: 10, // Margin between images
        // minPadding: 10, // Min padding
        // alwaysPadding: false, // Apply padding for images
        // preload: 3, // Amount of pre-loaded images from each end of the active image
        // resize: false, // Resize images
        // zoomToFit: true, // Zoom to fit
        // cropToFit: false, // Crop to fit
        // vertical: false, // Vertical thumbs
        // verticalThumbsRight: false, // Vertical thumbs at right
        // arrows: true, // Draw arrows
        arrowsColor: '#3399cc', // Arrows color
        // thumbs: true, // Draw thumbs
        // thumbsBackgroundColor: null, // Thumbs Background Color
        // thumbColor: null, // Thumb Color
        // thumbsPreview: true, // Thumb Preview
        thumbSize: 50, // Thumb size (height)
        // thumbMargin: 5, // Thumb margins
        thumbBorderWidth: 1, // Thumb border width
        // thumbBorderColor: null, // Thumb Border Color
        caption: true, // Display captions
        // html: null, // You can full html code of gallery here
        // onShowImg: null, // Custom function when we select image
        // shadows: true // Display shadows
    });
});

This is main initialization of fotorama gallery. Several styles was customized, another – no. I have added descriptions of all possible parameters of this gallery.

Here you can find official documentation of this gallery.

Step 4. Images

All gallery images is in ‘images’ folder.

Conclusion

I hope that today we made new nice photo gallery. Good luck in your projects!

Creating photo album with jQuery Chop Slider

Today I will tell you about new impressive jQuery slider – Chop. This slider have already had quite 200 different transition effects. Here are many 2D and 3D effects. Plus, here are you can find even few NonCss3 effects (to old IE browsers) and five effects for mobile browsers (for cellphones). Plus, we can create our own new transitions (if you want).

Here are links to demo and downloadable package:

                <div class="sl-descr">Good sculpture on Koh Samui island</div>
                <div class="sl-descr">That is such cute barmaid you can see here</div>
              </div>
              <div class="caption"></div>
            </div>

        </div>
    </body>
</html>

All slides wrap into own DIV parent elements with class name ‘slide’. Pay attention, that we have to create same amount of slider-pagination elements as amount of slider. Same for description.

Step 2. CSS

css/layout.css and css/chopslider.css

First file is layout of our demo page. Second one is CSS file of Chop slider. You can customize it as you like. Right now it contain next styles:

.wrapper {
	position:relative;
	margin-left:auto;
	margin-right:auto;
	width:960px;
	height:300px;
	display:block;

}

Step 3. JS

js/jquery.id.chopslider-2.2.0.free.min.js and js/jquery.id.cstransitions-1.2.min.js

These are two JS files in this slider. We just have to include it to our page.

js/main.js

jQuery(function(){
    $("#slider").chopSlider({
        /* slide element */
        slide : ".slide",
        /* controlers */
        nextTrigger : "a#slide-next",
        prevTrigger : "a#slide-prev",
        hideTriggers : true,
        sliderPagination : ".slider-pagination",
        /* captions */
        useCaptions : true,
        everyCaptionIn : ".sl-descr",
        showCaptionIn : ".caption",
        captionTransform : "scale(0) translate(-600px,0px) rotate(45deg)",
        /* autoplay */
        autoplay : true,
        autoplayDelay : 5000,
        /* for Browsers that support 3D transforms */
        t3D : csTransitions['3DFlips']['random'], /* all will be picked up randomly */
        t2D : [ csTransitions['multi']['random'], csTransitions['vertical']['random'] ],
        noCSS3 : csTransitions['noCSS3']['random'],
        mobile : csTransitions['mobile']['random'],
        onStart: function(){},
        onEnd: function(){}
    })
})

This is initialization of Chop slider. I set all effects (transitions) to random to display different effects to different browsers. Also I have enabled autoplay and display captions (descriptions).

Here you can find full documentation for this slider (with detailed explanation of all params).

Step 4. Images

For slider interface we are using few images (caption-bg.png, d-bg.png, navi.png, podium.png, shadow.png and sl-control.png). All these images available in our package. All slider images is in ‘slide_images’ folder.

Step 2. CSS

Now – our CSS styles. I will omit unnecessary styles of page layout, but will show you most important

css/main.css

.nav {
    background-color:#DDD;
    list-style:none outside none;
    overflow:hidden;
    padding:5px 140px;
}
.nav li {
    border-radius:10px;
    -moz-border-radius:10px;
    -webkit-border-radius:10px;

    border:2px outset #000000;
    color:#000;
    cursor:pointer;
    float:left;
    font-size:18px;
    font-weight:bold;
    margin-right:5px;
    padding:10px;
}

.demos {
    background-color:#DDD;
    list-style:none outside none;
    overflow:hidden;
    padding:5px 165px;
}
.demos li {
    border-radius:10px;
    -moz-border-radius:10px;
    -webkit-border-radius:10px;

    border:2px outset #000000;
    color:#000;
    float:left;
    font-size:18px;
    font-weight:bold;
    margin-right:5px;
    padding:10px;
}
.demos li a {
    color:#000;
    cursor:pointer;
    display:block;
    font-size:20px;
    font-weight:bold;
    height:30px;
    line-height:30px;
    text-decoration:none;
}

.grid {
    background-color:#DDD;
    list-style:none outside none;
    width:100%;
}
.grid li {
    border:1px solid #777777;
    float:left;
    height:240px;
    width:211px;

    transition:all 0.5s linear;
    -moz-transition:all 0.5s linear;
    -o-transition:all 0.5s linear;
    -webkit-transition:all 0.5s linear;
}
.grid li div {
    transition:all 0.5s ease-in-out;
    -moz-transition:all 0.5s ease-in-out;
    -o-transition:all 0.5s ease-in-out;
    -webkit-transition:all 0.5s ease-in-out;

    float:left;
}
.grid li .d1 {
    background:transparent url(../images/grid1.jpg) no-repeat top left;
    height:100%;
    width:211px;
}
.grid li .d2 {
    background:transparent url(../images/grid2.jpg) no-repeat top left;
    height:100%;
    width:0;
}
.grid li .d3 {
    background:transparent url(../images/grid3.jpg) no-repeat top left;
    height:100%;
    width:0;
}
.grid li .d4 {
    background:transparent url(../images/grid4.jpg) no-repeat top left;
    height:100%;
    width:0;
}
.grid li .d5 {
    background:transparent url(../images/grid5.jpg) no-repeat top left;
    height:100%;
    width:0;
}
.grid li#g2 div {
    background-position:-211px 0;
}
.grid li#g3 div {
    background-position:-422px 0;
}
.grid li#g4 div {
    background-position:0 -240px;
}
.grid li#g5 div {
    background-position:-211px -240px;
}
.grid li#g6 div {
    background-position:-422px -240px;
}

As you can see – each grid cell element (LI) have some defined background, but with own background positions. And, I will use jQuery ‘animate’ to shift these positions when we will switch our images (through navigation)

Step 3. jQuery

js/main.js

$(function(){
    $(".nav li").hover(
      function () {
        $('.grid li div').stop().animate({width:"0"},0);

        var ind = $(".nav li").index(this);
        $($('.grid li#g1 div')[ind]).stop().animate({width:"211px"},0);
        $($('.grid li#g2 div')[ind]).stop().animate({width:"211px"},50);
        $($('.grid li#g3 div')[ind]).stop().animate({width:"211px"},100);
        $($('.grid li#g4 div')[ind]).stop().animate({width:"211px"},150);
        $($('.grid li#g5 div')[ind]).stop().animate({width:"211px"},200);
        $($('.grid li#g6 div')[ind]).stop().animate({width:"211px"},250);
      }
    );
});

As you can see – all very easy.

Creating own ajax poll system

Today I prepared new interesting tutorial – we will creating own Poll system (AJAX) for your projects with PHP. Polls, answers and results I going to keep in single SQL table. When we will vote for one of variants – jQuery will POST data, and then we will animate our results in realtime.

Live Demo

download in package

Now – download the source files and lets start coding !

Step 1. SQL

We will need to add one table into our database:

CREATE TABLE `s183_polls` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `title` varchar(255) default '',
  `answers` text NOT NULL,
  `results` varchar(60) NOT NULL default '',
  `total_votes` int(10) NOT NULL default '0',
  `when` int(10) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8;

INSERT INTO `s183_polls` (`id`, `title`, `answers`, `results`, `total_votes`, `when`) VALUES
(NULL, 'First poll question', 'Answer 1<sep>Answer 2<sep>Answer 3<sep>Answer 4', '', 0, UNIX_TIMESTAMP()),
(NULL, 'Second poll question', 'Answer 21<sep>Answer 22<sep>Answer 23<sep>Answer 24', '', 0, UNIX_TIMESTAMP()+1),
(NULL, 'Third poll question', 'Answer 31<sep>Answer 32<sep>Answer 33<sep>Answer 34', '', 0, UNIX_TIMESTAMP()+2),
(NULL, 'Forth poll question', 'Answer 41<sep>Answer 42<sep>Answer 43<sep>Answer 44', '', 0, UNIX_TIMESTAMP()+3),
(NULL, 'Fifth poll question', 'Answer 51<sep>Answer 52<sep>Answer 53<sep>Answer 54', '', 0, UNIX_TIMESTAMP()+4);

This is pur main Polls table.

Step 2. PHP

Here are source code of our main file:

index.php

<?php
// disable  warnings
if (version_compare(phpversion(), "5.3.0", ">=")  == 1)
  error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);
else
  error_reporting(E_ALL & ~E_NOTICE); 

require_once('classes/CMySQL.php'); // including service class to work with database

if ($_POST['do'] == 'vote') { // in case if we submitted poll
    $iPollId = (int)$_POST['id'];
    $iAnswer = (int)$_POST['answer'];

    if ($iPollId && $iAnswer >= 0 && ! isset($_COOKIE['av' . $iPollId])) {
        // get poll info
        $aPollInfo = $GLOBALS['MySQL']->getRow("SELECT * FROM `s183_polls` WHERE `id` = '{$iPollId}'");

        // updating of poll results
        $aAnswers = explode('<sep>', $aPollInfo['answers']);
        $iCnt = count($aAnswers);
        $aVotes = ($aPollInfo['results'] == '') ? array_fill(0, $iCnt, 0) : explode('<sep>', $aPollInfo['results']);
        $aVotes[$iAnswer]++;
        $iVotesCount = array_sum($aVotes);
        $sVotes = implode('<sep>', $aVotes);
        $GLOBALS['MySQL']->res("UPDATE `s183_polls` SET `results` = '{$sVotes}', `total_votes` = {$iVotesCount} WHERE `id` = {$iPollId}");

        // recalculation of percents
        $iVotesCnt = $aPollInfo['total_votes'] + 1;
        $aPercents = array();
        foreach ($aAnswers as $i => $sAnswer) {
            $aPercents[$i] = round( (0 != $iVotesCnt ? (( $aVotes[$i] / $iVotesCnt ) * 100) : 0), 1);
        }

        setcookie('av' . $iPollId, '1', time() + 24*3600, '/'); // easy protection from duplicate votes

        // return back to JS
        echo json_encode($aPercents);
        exit;
    } else {
        exit;
    }
}

$sCode = '';
$iItemId = (int)$_GET['id'];
if ($iItemId) { // View item output
    $aItemInfo = $GLOBALS['MySQL']->getRow("SELECT * FROM `s183_polls` WHERE `id` = '{$iItemId}'"); // get poll info

    $aAnswers = explode('<sep>', $aItemInfo['answers']);
    $iCnt = count($aAnswers);
    $aVotes = ($aItemInfo['results'] == '') ? array_fill(0, $iCnt, 0) : explode('<sep>', $aItemInfo['results']);

    $iVotesCnt = $aItemInfo['total_votes'];

    $sAnswers = '';
    foreach ($aAnswers as $i => $sAnswer) {
        $fPercent = round((0 != $iVotesCnt ? (($aVotes[$i] / $iVotesCnt) * 100) : 0), 1);
        $sAnswers .= "<div id='{$i}'><div>{$sAnswer} (<span>{$aVotes[$i]}</span>)</div><div class='row' style='width:{$fPercent}%'>{$fPercent}%</div></div>";
    }

            function(data){
                if (data) {
                    var da = eval('(' + data + ')');
                    for (var p in da) {
                        $($('.answers > div .row')[p]).animate({
                            width: da[p] + "%"

When we open this page in first time – it will draw list of polls. Each poll unit have own page. At this page we going to display Poll title, date of adding and all possible answers. On click – script will send (POST) data to same script. In this moment we are adding this vote, and then we will send back new percentages for all variants. And jQuery will re-animate all these bars. I added my comments in most of places for better understanding.

I have another one PHP file in my project:

classes/CMySQL.php

This is service class to work with database prepared by me. This is nice class which you can use too. Database connection details present in that class file in few variables, sure that you will able to configure this to your database. I will not publish sources of this file – this is not necessary right now. Available in package.

Step 3. JS

js/jquery-1.5.2.min.js

This is just jQuery library. Available in package.

Step 4. CSS

Now – all used CSS styles:

css/main.css

    margin:0;
    padding:0;

PHP guestbook

Today I prepared new interesting tutorial – I will tell how you can create ajax PHP guestbook with own unique design. Our records will be saved into SQL database. This table will contain next info: name of sender, email, guestbook record, date-time of record and ip of sender. Of course, we will use jQuery too (to make it ajaxy). One of important features will spam protection (we can post no more than one record every 10 minutes)!

Now – download the source files and lets start coding !

Step 1. SQL

We need to add one table to our database (to store our records):

CREATE TABLE IF NOT EXISTS `s178_guestbook` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `name` varchar(255) default '',
  `email` varchar(255) default '',
  `description` varchar(255) default '',
  `when` int(11) NOT NULL default '0',
  `ip` varchar(20) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Step 2. PHP

Here are source code of our main file:

guestbook.php

<?php
// disabling possible warnings
if (version_compare(phpversion(), "5.3.0", ">=")  == 1)
  error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);
else
  error_reporting(E_ALL & ~E_NOTICE); 

require_once('classes/CMySQL.php'); // including service class to work with database

// get visitor IP
function getVisitorIP() {
    $ip = "0.0.0.0";
    if( ( isset( $_SERVER['HTTP_X_FORWARDED_FOR'] ) ) && ( !empty( $_SERVER['HTTP_X_FORWARDED_FOR'] ) ) ) {
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    } elseif( ( isset( $_SERVER['HTTP_CLIENT_IP'])) && (!empty($_SERVER['HTTP_CLIENT_IP'] ) ) ) {
        $ip = explode(".",$_SERVER['HTTP_CLIENT_IP']);
        $ip = $ip[3].".".$ip[2].".".$ip[1].".".$ip[0];
    } elseif((!isset( $_SERVER['HTTP_X_FORWARDED_FOR'])) || (empty($_SERVER['HTTP_X_FORWARDED_FOR']))) {
        if ((!isset( $_SERVER['HTTP_CLIENT_IP'])) && (empty($_SERVER['HTTP_CLIENT_IP']))) {
            $ip = $_SERVER['REMOTE_ADDR'];
        }
    }
    return $ip;
}

// get last guestbook records
function getLastRecords($iLimit = 3) {
    $sRecords = '';
    $aRecords = $GLOBALS['MySQL']->getAll("SELECT * FROM `s178_guestbook` ORDER BY `id` DESC LIMIT {$iLimit}");
    foreach ($aRecords as $i => $aInfo) {
        $sWhen = date('F j, Y H:i', $aInfo['when']);
        $sRecords .= <<<EOF
<div class="record" id="{$aInfo['id']}">
    <p>Record from {$aInfo['name']} <span>({$sWhen})</span>:</p>
    <p>{$aInfo['description']}</p>
</div>
EOF;
    }
    return $sRecords;
}

if ($_POST) { // accepting new records

    $sIp = getVisitorIP();
    $sName = $GLOBALS['MySQL']->escape(strip_tags($_POST['name']));
    $sEmail = $GLOBALS['MySQL']->escape(strip_tags($_POST['name']));
    $sDesc = $GLOBALS['MySQL']->escape(strip_tags($_POST['text']));

    if ($sName && $sEmail && $sDesc && $sIp) {

        // spam protection
        $iOldId = $GLOBALS['MySQL']->getOne("SELECT `id` FROM `s178_guestbook` WHERE `ip` = '{$sIp}' AND `when` >= UNIX_TIMESTAMP() - 600 LIMIT 1");
        if (! $iOldId) {

            // allow to add comment
            $GLOBALS['MySQL']->res("INSERT INTO `s178_guestbook` SET `name` = '{$sName}', `email` = '{$sEmail}', `description` = '{$sDesc}', `when` = UNIX_TIMESTAMP(), `ip` = '{$sIp}'");

            // drawing last 10 records
            $sOut = getLastRecords();
            echo $sOut;
            exit;
        }
    }
    echo 1;
    exit;
}

// drawing last 10 records
$sRecords = getLastRecords();

ob_start();

When we open this page we will see book, at left side we will draw list of last three records, at right – form of posting new records. When we submitting form – script sending POST data (to same php page), script saving this data to database, and returning us list of fresh 3 records. Then, via fading effect we draw returned data at left column. All code contains comments – read it for better understanding code. Ok, next PHP file is:

classes/CMySQL.php

This is my own service class to work with database. This is nice class which you can use too.
