使用方法：

覆盖到\phpcms\libs\functions这个目录下

后台添加字段（类型只能是联动菜单，和下拉列表）、然后选择作为筛选字段。

模板使用
===============================
 您已选择:
 {loop get_parent_url($modelid,'diqu') $r}
 <a href="{$r['url']}">{$r['name']}</a>
 {/loop}

==============================
联动菜单使用：

{php $zones = show_linkage(1,0,$modelid,'diqu')}
 {if !empty($zones)}
 <dl class="clearfix">
 <dt>地区：</dt>
 <dd class="more">全部展开</dd>
 <dd class="item_list">
 {loop $zones $r}
 {$r['menu']}
 {/loop}
 </dd>
 </dl>
 {/if}

或
{php $zones = show_linkage(3360,0,3,'bzfl', array('catid'=>9))}
                    {if !empty($zones)}
                                    {loop $zones $r}
                                {$r['menu']}
                            {/loop}
                    {/if}        
==========================
下拉列表使用

{loop filters('xz',$modelid) $r}
                {$r[menu]}
        {/loop}
==========================
配合列表标签使用：

{php $sql = structure_filters_sql($modelid);}
        {pc:content action="lists" where="$sql" catid="$catid" modelid="$modelid" num="10" page="$page"}

伪静态：
.ht  : RewriteRule ^.*list-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)\.html$ /index.php?m=content&c=index&a=lists&catid=$1&bzcolor=$2&bzfl=$3&pbsize=$4&pcsize=$5&sjsize=$6&page=$7

.is : <rule name="rD">
 <match url="^.*list-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)-(\d*)\.html$" />
 <action type="Rewrite" url="/index.php?m=content&c=index&a=lists&catid={R:1}&bzcolor={R:2}&bzfl={R:3}&pbsize={R:4}&pcsize={R:5}&sjsize={R:6}&page={R:7}" />
 </rule>
