thinkphp功能回覆留言

这篇文章主要介绍了ThinkPHP无限级分类原理实现留言与回复功能实例,并附带有完整的项目源码下载供大家学习参考,非常具有实用价值,需要的朋友可以参考下

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：

DROP TABLE IF EXISTS `wb_guestbook`;
CREATE TABLE `eway_guestbook` (
