如何实现dedecms后台栏目管理显示未审核文章数量

//获取所有栏目的未审核文档ID数
    function UpdateCatalogNumw()
    {
        $this->dsql->SetQuery("SELECT typeid,count(typeid) as dd FROM `dede_arctiny` where arcrank =-1 group by typeid");
        $this->dsql->Execute();
        while($row = $this->dsql->GetArray())
        {
            $this->CatalogNumsw[$row['typeid']] = $row['dd'];
        }
    }
    function GetTotalArcw($tid)
    {
        if(!is_array($this->CatalogNumsw))
        {
            $this->UpdateCatalogNumw();
        }
        if(!isset($this->CatalogNumsw[$tid]))
        {
            return "";
        }
        else
        {
            $totalnum = 0;
            $ids = explode(',',GetSonIds($tid));
            foreach($ids as $tid)
            {
                if(isset($this->CatalogNumsw[$tid]))
                {
                    $totalnum += $this->CatalogNumsw[$tid];
                }
            }
            return " | <font color=red>".$totalnum."</font> | <a href='content_i_list.php?arcrank=-1&cid=".$tid."'>图</a> | <a href='content_list.php?

arcrank=-1&cid=".$tid."'>文</a>";
