一、dedecms v5.6列表頁標簽{dede:list}增加按權重排序標簽
dedecms v5.6版本已經中已經添加權重字段，并且在{dede:arclist}標簽中默認可以使用。但在列表頁的標簽 {dede:list}中是還是無法按權重實現排序。其實解決方法很簡單，下面給出方法：
1、打開\include\目錄中的arc.listview.class.php文件，搜索“排序方式”，然后在
else if($orderby=="lastpost") {
$ordersql = " order by arc.lastpost $orderWay";
}
else if($orderby == "weight") {
$ordersql = " order by arc.weight asc";
}
else {
$ordersql=" order by arc.sortrank $orderWay";
}
這段代碼中間添加以上紅色代碼。
4、向下找到if(ereg('hot|click|lastpost',$orderby))或者是if(preg_match('/hot|click|lastpost/', $orderby))修改成if(ereg('hot|click|lastpost|weight',$orderby))或者是if(preg_match('/hot|click|lastpost|weight/', $orderby)) ，保存文件。
這個時候在列表頁里就可以使用{dede:list pagesize='5' orderby='weight'} 進行排序了。
二、DEDE 5.7 首頁【arclist】增加按權重排序
1、在織夢系統中找到以下目錄\include\taglib中的arclist.lib.php文件并打開
大約在74 、75行找到：
// arclist是否需要weight排序,默認為"N",如果需要排序則設置為"Y"
$isweight = $ctag->GetAtt('isweight');
把這行修改為：
$weight = $ctag->GetAtt('weight');
大約在327行找到
//文檔排序的方式
$ordersql = '';
if($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";
修改為：
//文檔排序的方式
$ordersql = '';
if($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') $ordersql = " ORDER BY rand()";
else if($orderby == 'weight') $ordersql = " order by arc.weight asc";//如果沒有特定設置排序則按照權重先排序
else $ordersql = " ORDER BY arc.sortrank $orderWay";
OK 現在把這個文檔保存了 我們就可以在首頁使用 orderby='weight' 進行排序了。
