tag相关列表中调用的文章关联url无法识别

 {related module=all field=id,title,url,description,keywords,updatetime,hits tag=$tag.tags page=1 pagesize=10 urlrule=$urlrule}
    {$url}
     {php $kws=dr_get_content_kws($t.keywords);}
                                                {loop $kws $name $url}
                                                       {$url}
                                                {/loop}
 {/related}

棕色url可以识别出来，红色url识别不出来，请问如何解决，谢谢！！
