《PHP实例：ThinkPHP无限级分类原理实现留言与回复功能实例》要点： PHP教程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： PHP教程功能上,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! PHP教程程序效果如下图所示： PHP教程 PHP教程完整源码点击此处本站下载. PHP教程数据表：
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,???? ?
