织梦dedeCMS列表标签按照下载次数排序

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.’)’;

}
