dede5.6和5.7版本中實(shí)現(xiàn)dede:list按權(quán)重排序

一、dedecms v5.6列表頁標(biāo)簽{dede:list}增加按權(quán)重排序標(biāo)簽

dedecms v5.6版本已經(jīng)中已經(jīng)添加權(quán)重字段，并且在{dede:arclist}標(biāo)簽中默認(rèn)可以使用。但在列表頁的標(biāo)簽 {dede:list}中是還是無法按權(quán)重實(shí)現(xiàn)排序。其實(shí)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(gè)時(shí)候在列表頁里就可以使用{dede:list pagesize='5' orderby='weight'} 進(jìn)行排序了。

二、DEDE 5.7 首頁【arclist】增加按權(quán)重排序

1、在織夢系統(tǒng)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(rèn)為"N",如果需要排序則設(shè)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(shè)置排序則按照權(quán)重先排序

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

OK 現(xiàn)在把這個(gè)文檔保存了 我們就可以在首頁使用 orderby='weight' 進(jìn)行排序了。
