dede:arclist orderby=weight dedecms列表页文章按权重排序无效问题

　　平时我们有时会发现dedecms列表页文章按权重排序无效问题，找到list解析文件include/arc.listview.class.ph，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，大概在771行，加入下面红色代码

    //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，在812行左右，加入|weight参数

        //如果不用默认的sortrank或id排序，使用联合查询（数据量大时非常缓慢）
        if(preg_match('/hot|click|lastpost|weight/', $orderby))

　　有的朋友反映说改了不能用，再改一个地方：/include/taglib/arclist.lib.php加入红色的语句

    //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 == 'weight') $ordersql = "  ORDER BY arc.weight $orderWay";
    else if($orderby == 'scores') $ordersql = "  ORDER BY arc.scores $orderWay";
    //功能：增加按好评数和差评数调用
    else if($orderby == 'goodpost') $ordersql = " order by arc.goodpost $orderWay";
    else if($orderby == 'badpost') $ordersql = " order by arc.badpost $orderWay";
    else if($orderby == 'rand') $ordersql = "  ORDER BY rand()";
    else $ordersql = " ORDER BY arc.sortrank $orderWay";

　　arclist 对weight的排序也不准确，在模板调用时,需要加上一个isweight的属性,如下红色代码

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