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 | 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 | 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 | 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
