织梦的arclist标签可以按照文章点击次数、发布日期、得分等进行排序，今天有个客户需要按照软件下载次数进行排列，于是做了简单二次开发。

首先找到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.')';

}
