织梦默认情况下是没有开启weight排序的需要修改arclist.lib.php
1、 在织梦系统中找到以下目录include aglib中的arclist.lib.php文件并打开，大约在74 、75行找到：
<span style="font-size:14px;"><span style="font-family:tahoma,geneva,sans-serif;">1 // arclist是否需要weight排序,默认为"N",如果需要排序则设置为"Y"
$isweight = $ctag->GetAtt('isweight');
</span></span>
把这行修改为
<span style="font-size:14px;"><span style="font-family:tahoma,geneva,sans-serif;">
$weight = $ctag->GetAtt('weight');
</span></span>
2、大约在327行找到
//文档排序的方式
$ordersql = '';
if($orderby=='hot' || $orderby=='click') $ordersql = " ORDER BY arc.click $orderWay";
else if($orderby == 'sortrank' || $orderby=='pubdate') $ordersql = " ORDER BY arc.sortrank $orderWay";
else if($orderby == 'id') $ordersql = " ORDER BY arc.id $orderWay";
else if($orderby == 'near') $ordersql = " ORDER BY ABS(arc.id - ".$arcid.")";
else if($orderby == 'lastpost') $ordersql = " ORDER BY arc.lastpost $orderWay";
else if($orderby == 'scores') $ordersql = " ORDER BY arc.scores $orderWay";
else if($orderby == 'rand') $ordersql = " ORDER BY rand()";
<span style="font-size:14px;"><span style="font-family:tahoma,geneva,sans-serif;">
else if($orderby == 'weight') $ordersql = " order by arc.weight asc";//在这里增加一行---->如果没有特定设置排序则按照权重先排序
</span></span>
