帝国cms列表页list.var调用tags怎么实现

$nsmalltext=$r[smalltext]; 
$ntext=strip_tags($nsmalltext);//去除内容简介里的HTML标签 
$newtext=esub($ntext,100,'...') ;//限制100字 
$keyboard=$r[keyboard]; 
$r_tag=explode(",",$keyboard); 
$tempid=1;//这里是搜索模板ID 
for($i=0;$i<count($r_tag);$i++) 
{ 
if($r_tag[$i]) 
{ 
$tagslink=$public_r[newsurl]."e/tags/?tagname=".$r_tag[$i];//链接 
$tagslink=$public_r[newsurl]."e/search/?searchget=1&tbname=$tbname& amp;tempid=$tempid&show=keyboard&keyboard=".$r_tag[$i];//如果链接到搜索 页面用此行代码，如果不是请删除 
$tags.="<a href=&#39;$tagslink&#39; target=&#39;_blank&#39;>".$r_tag[$i]."</a> "; 
} 
} 
$listtemp=&#39;<div class="m_2"> 
<div class="m_2_a"><a href="/html/10752.html" title="[!--oldtitle--]">[!--title--]</a>[[!--newstime--]]</div>
