織夢dedecms  list orderby=weight 按權重排序無效問題 ，找到list解析文件include/arc.listview.class.php 

 發現排序規則里面并沒有按照weight排序的判斷，于是乎修改程序加入排序規則 

//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";
  }

同時修改條件if(ereg('hot|click|lastpost',$orderby))為if(ereg('hot|click|lastpost|weight',$orderby))， [搜索 hot|click|lastpost 定位]

另外：

arclist 對weight的排序也不準確，需要加上一個isweight的屬性

{dede:arclist typeid='32' pagesize='20' isweight='Y' orderby='weight' orderway='asc'} 。
