找到list解析文件include/arc.listview.class.php
发现排序规则里面并没有按照weight排序的判断，于是乎修改程序加入排序规则
//排序方式
$ordersql = '';
if($orderby=="senddate" || $orderby=="id") {
$ordersql=" order by arc.id $orderWay";
}
else if($orderby=="hot" || $orderby=="click") {
$ordersql = " order by arc.click $orderWay";
}
else if($orderby=="lastpost") {
$ordersql = " order by arc.lastpost $orderWay";
}
else if($orderby=="weight") {
$ordersql = " order by arc.weight $orderWay";
}
else {
$ordersql=" order by arc.sortrank $orderWay";
}
同时修改条件if(ereg('hot|click|lastpost',$orderby))为if(ereg('hot|click|lastpost|weight',$orderby))， [搜索 hot|click|lastpost 定位]
另外：
arclist 对weight的排序也不准确，需要加上一个isweight的属性
{dede:arclist typeid='32' pagesize='20' isweight='Y' orderby='weight' orderway='asc'}
