首先我把单选的代码贴出来,这个是我参考其他网站的,多选也是基于这个单选修改的,所以如果要做多选的话,也请先把单选的这些代码配置好.
联动筛选单选功能

首先需要说明的是这个功能需要在模板里面用到php标签，所以需要在后台模板引擎禁用标签里面解除这个标签的禁用，具体方法：
后台——系统——系统基本参数——其它选项——模板引擎禁用标签：php
将这个PHP去掉后保存就可以了！
好了，下面开始正题了。
首先需要修改2个PHP文件，都是include目录下面的。
1、修改arc.listview.class.php文件，这文件改动比较大，建议大家直接下载附件压缩包里面的文件替换，如果你之前对这个文件 改动过的话，请在下载下来的压缩包里的这个文件里面搜索有“Darren中博客”这些注释的这些地方，都是修改过的，然自己手动将有注释的代码插入到自己 的文件里面！
2、修改extend.func.php文件，在其最后面添加如下代码：
