dedecms 首页arclist按照'weight'排序

织梦默认情况下是没有开启weight排序的需要修改arclist.lib.php   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:   <span style="font-size:14px;"><span style="font-family:tahoma,geneva,sans-serif;">1 // 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'); </span></span>   把这行修改为   <span style="font-size:14px;"><span style="font-family:tahoma,geneva,sans-serif;"> $weight = $ctag->GetAtt('weight'); </span></span>   2、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') $ordersql = "  ORDER BY rand()";   <span style="font-size:14px;"><span style="font-family:tahoma,geneva,sans-serif;"> else if($orderby == 'weight') $ordersql = "  order by arc.weight asc";//在这里增加一行---->如果没有特定设置排序则按照权重先排序 </span></span>
