仿cnbeta的关键是每个栏目对应一个缩略图，下面是我的一个思路：

首先通过后台SQL命令行工具给“栏目”对应的表：dede_arctype表加一个字段，用来放图片
具体命令是：

Copy code

ALTER TABLE dede_arctype  ADD typelitpic  varchar(80) NOT NULL DEFAULT ‘’;

将来图片的地址就是对应存放在typelitpic字段，你可以根据自己的喜欢取名；

就是让{dede:arclist /} 能获取 dede_arctype.typelitpic里的值

方法是在后台：◇标签源码碎片管理 >> 修改标签

修改 arclist.lib.php

Copy code
