之前写过这篇文章《织梦DEDECMS5.7实现联动筛选（支持多条件多级选项）》下面二次开发织梦联动筛选是之前升级版，修复手机端无法加载_m.htm列表模板BUG：
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：
登录后台 >> 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删除后保存就可以了！
联动筛选功能分为两种，单选和多选，好了，下面开始正题。
一、联动功能 单选
首先需要修改2个PHP文件，用编辑器打开include目录下的 arc.listview.class.php 和 extend.func.php
1、修改arc.listview.class.php，这个文件改动的地方较多，建议大家直接下载附件压缩包里面的文件，直接替换。
注意：如果你曾经对arc.listview.class.php这个文件进行过改动的话，请先备份原文件，再对比“参照表”逐一手动替换！
2、修改extend.func.php文件，这个文件改动很简单，直接在最后面添加如下代码：
特别注意：以下代码中有4处“【分隔符】”字样，请自行删除。
// 字符过滤函数
function wwwcms_filter($str,$stype="inject") {
if ($stype=="inject") {
$str = str_replace(
array( "select", "insert", "update", "delete", "alter", "cas", "union", "into", "load_file", "outfile", "create", "join", "where", "like", "drop", "modify", "rename", "'", "/*", "*", "../", "./"),
array("","","","","","","","","","","","","","","","","","","","","",""),
$str);
} else if ($stype=="xss") {
$farr = array("/\s+/" ,

array("<",">","","","","","","",""),
$str);
