ThinkPHP無限級分類原理實(shí)現(xiàn)留言與回復(fù)功能實(shí)例

這篇文章主要介紹了ThinkPHP無限級分類原理實(shí)現(xiàn)留言與回復(fù)功能實(shí)例,并附帶有完整的項(xiàng)目源碼下載供大家學(xué)習(xí)參考,非常具有實(shí)用價(jià)值,需要的朋友可以參考下

本文所述留言板程序使用了無限級分類的原理，可以實(shí)現(xiàn)無限級留言與回復(fù)。留言列表gclist保留了留言層次空格，使留言--回復(fù)層次分明。分享給大家供大家參考。具體分析如下：

功能上，本程序可以實(shí)現(xiàn)無限級留言與回復(fù)，即對留言回復(fù)，對回復(fù)的留言回復(fù)。當(dāng)然你也可以作有限制的控制，使其只對留言回復(fù)，關(guān)鍵是在模板代碼中去掉回復(fù)的留言中的“回復(fù)該留言”即可。歡迎去拍磚！

程序效果如下圖所示：

-- Table structure for `wb_guestbook`

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