dedecms 标签按照权重排序

  大约在74 、75行找到：

      // 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');

把这行修改为：

  $weight = $ctag->GetAtt('weight');

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()";
    else $ordersql = " ORDER BY arc.sortrank $orderWay"; 

在其中添加 else if($orderby == 'weight') $ordersql = "  order by arc.weight $orderWay";//如果设置按权重排序，则按权重排序
