dedecms织梦系统如何按照软件下载次数排序？

dedecms织梦cms的arclist标识能够依照文章内容点一下频次，公布日期，评分等开展排列，今日有一个顾客要求依照软件免费下载频次开展排序，因此干了简易二次开发，最先寻找include文件目录下边的taglib文件目录里的arclist.lib.php文件在376行后添加如下所示编码
 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.')';
 }
