织梦dedeCMS列表标签按照下载次数排序

muban大师

DEDECMS按照下载次数排序，排序在SQL语句里无非就是order by 下载次数 desc，知道了这个然后我们就看需要改哪里了。
        找到include目录下面的taglib目录里的arclist.lib.PHP文件在376行后加入如下代码
        if($orderby == 'down')
        {
        $sql = "select SUM(downloads) as down_num,id from dede_downloads group by id ORDER BY down_num DESC LIMIT 0]15";
        $dsql->Execute('me',$sql);
        while($drow = $dsql->GetArray() )
        {
        $arr[, = $drow['id',;
        }
        $dstr = implode(",",$arr);
        if($orwhere!='')
        {
        $orwhere .= " AND arc.id in($dstr)";
        }else{
        $orwhere .= " where arc.id in($dstr)";
        }
        $ordersql = 'ORDER BY field(arc.id,'.$dstr.')';
        }
