DEDE 5.7首页按权重排序：实现高效网站内容展示的25字标题

DEDE 5.7 首页怎么按权重排序?

DEDE 5.7 首页【arclist】增加按权重排序

1、在织梦系统中找到以下目录\include\taglib中的arclist.lib.php文件并打开

   大约在74 、75行找到：

推荐学习：dedecms教程

  // 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";

修改为：

    //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') $ordersql = "  ORDER BY rand()";
    else if($orderby == 'weight') $ordersql = "  order by arc.weight $orderWay";//如果没有特定设置排序则按照权重先排序
    else $ordersql = " ORDER BY arc.sortrank $orderWay";

OK   现在把这个文档保存了  我们就可以在首页使用 orderby='weight' 进行排序了。
