How to filter and classify phpcms articles?

最后，在要調(diào)用產(chǎn)品篩選的欄目模板頁(yè)添加標(biāo)簽，如下。

<span>性別：</span>    
{loop filters(&#39;xingbie&#39;,$modelid) $r}  
{$r[menu]}  
{/loop}

{php $sql = structure_filters_sql($modelid)}  
{php $urlrule = makeurlrule()}  
    {pc:content action="lists" where="$sql" catid="$catid" num="10" order="id DESC" page="$page"  urlrule="$urlrule"}  
      
        <ul class="photo-list picbig">  
            {loop $data $r}  
            <li>  
            <div class="img-wrap">
