ThinkPHP无限级分类原理实现留言与回复功能实例

作者:网络 更新:2018-06-26 10:17:42 阅读:219次

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:

-- ----------------------------     
-- Table structure for `wb_guestbook`     
-- ----------------------------     
DROP TABLE IF EXISTS `wb_guestbook`;     
CREATE TABLE `eway_guestbook` (     
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
