Have you thought about own facebook-style photo gallry system with comments? I have and today I prepared it for you. In this post i explained the easy way to create your Facebook style photo gallery with comments application. I used to create the ajax, php, and mysql as database to store the gallery details.
Create database table gallery
1 2 3 4 5 6 7 8 9 10 | CREATE TABLE IF NOT EXISTS `gallery` ( `id` int(10) unsigned NOT NULL auto_increment, `title` varchar(255) default '', `filename` varchar(255) default '', `description` text NOT NULL, `when` int(11) NOT NULL default '0', `comments_count` int(11) NOT NULL default '0', PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; |
Insert some example data
1 2 3 4 5 6 7 8 9 10 11 12 | INSERT INTO `gallery` (`title`, `filename`, `description`, `when`) VALUES ('Item #1', 'photo1.jpg', 'Description of Item #1', UNIX_TIMESTAMP()), ('Item #2', 'photo2.jpg', 'Description of Item #2', UNIX_TIMESTAMP()+1), ('Item #3', 'photo3.jpg', 'Description of Item #3', UNIX_TIMESTAMP()+2), ('Item #4', 'photo4.jpg', 'Description of Item #4', UNIX_TIMESTAMP()+3), ('Item #5', 'photo5.jpg', 'Description of Item #5', UNIX_TIMESTAMP()+4), ('Item #6', 'photo6.jpg', 'Description of Item #6', UNIX_TIMESTAMP()+5), ('Item #7', 'photo7.jpg', 'Description of Item #7', UNIX_TIMESTAMP()+6), ('Item #8', 'photo8.jpg', 'Description of Item #8', UNIX_TIMESTAMP()+7), ('Item #9', 'photo9.jpg', 'Description of Item #9', UNIX_TIMESTAMP()+8), ('Item #10', 'photo10.jpg', 'Description of Item #10', UNIX_TIMESTAMP()+9); |
Create comments table
1 2 3 4 5 6 7 8 9 10 11 | CREATE TABLE IF NOT EXISTS `comments` ( `c_id` int(11) NOT NULL AUTO_INCREMENT , `c_item_id` int(12) NOT NULL default '0', `c_ip` varchar(20) default NULL, `c_name` varchar(64) default '', `c_text` text NOT NULL , `c_when` int(11) NOT NULL default '0', PRIMARY KEY (`c_id`), KEY `c_item_id` (`c_item_id`) ) ENGINE=MYISAM DEFAULT CHARSET=utf8; |
Create index.php
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 | <?php require('classes/CMySQL.php'); // include service classes to work with database and comments require('classes/CMyComments.php'); if ($_POST['action'] == 'accept_comment') { echo $GLOBALS['MyComments']->acceptComment(); exit; } // prepare a list with photos $sPhotos = ''; $aItems = $GLOBALS['MySQL']->getAll("SELECT * FROM `gallery` ORDER by `when` ASC"); // get photos info foreach ($aItems as $i => $aItemInfo) { $sPhotos .= '<div class="photo"><img src="images/thumb_'.$aItemInfo['filename'].'" id="'.$aItemInfo['id'].'" /><p>'.$aItemInfo['title'].' item</p><i>'.$aItemInfo['description'].'</i></div>'; } ?> <!DOCTYPE html> <html lang="en"><head> <meta charset="utf-8" /> <title>Facebook style photo gallery with comments By Freewebmentor</title> <!-- Link styles --> <link href="css/style.css" rel="stylesheet" type="text/css" /> <!-- Link scripts --> <script src="https://www.google.com/jsapi"></script> <script> google.load("jquery", "1.7.1"); </script> <script src="js/script.js"></script> </head> <body> <header> <h2>Facebook like photo gallery with comments</h2> <a href="https://freewebmentor.com/2014/10/facebook-style-photo-gallery-comments.html" class="stuts">Back to original tutorial</a> </header> <!-- Container with last photos --> <div class="container"> <h1>Last photos:</h1> <?= $sPhotos ?> </div> <!-- Hidden preview block --> <div id="photo_preview" style="display:none"> <div class="photo_wrp"> <img class="close" src="images/close.gif" /> <div style="clear:both"></div> <div class="pleft">test1</div> <div class="pright">test2</div> <div style="clear:both"></div> </div> </div> </body></html> |
