ThinkPHP

本文所述留言板程序使用了无限级分类的原理,可以实现无限级留言与回复。留言列表gclist保留了留言层次空格,使留言--回复层次分明。分享给大家供大家参考。具体分析如下:

功能上,本程序可以实现无限级留言与回复,即对留言回复,对回复的留言回复。当然你也可以作有限制的控制,使其只对留言回复,关键是在模板代码中去掉回复的留言中的“回复该留言”即可。欢迎去拍砖!

程序效果如下图所示:

数据表:

代码如下:

-- ----------------------------
-- Table structure for `wb_guestbook`
-- ----------------------------
DROP TABLE IF EXISTS `wb_guestbook`;
CREATE TABLE `eway_guestbook` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`pid` int(10) NOT NULL,
`email` varchar(50) NOT NULL,
`path` varchar(100) NOT NULL,
`username` varchar(30) NOT NULL,
`updatetime` int(10) NOT NULL,
`ip` varchar(15) NOT NULL,
`url` varchar(200) NOT NULL,
`inputtime` int(10) NOT NULL,
`content` text NOT NULL,
`verify` varchar(32) NOT NULL,
`isreply` tinyint(1) NOT NULL,
`status` tinyint(1) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=42 DEFAULT CHARSET=utf8;
