有时我们需要做文章排名,比如指定第一名到第三名在前面,这样就用到这个权重排序方法。
dede:list 的方法
1、找到\\include\\arc.listview.class.php
文件。
2、修改代码:在文件第727行处添加按weight排序判断代码。
//排序方式 $ordersql = ''; if ($orderby == "senddate" || $orderby == "id") { $ordersql = " ORDER BY arc.id {$orderWay}"; } else { if ($orderby == "hot" || $orderby == "click") { $ordersql = " ORDER BY arc.click {$orderWay}"; } else { if ($orderby == "lastpost") { $ordersql = " ORDER BY arc.lastpost {$orderWay}"; } else { if ($orderby == "weight") { $ordersql = " ORDER BY arc.weight {$orderWay}"; } else { $ordersql = " ORDER BY arc.sortrank {$orderWay}"; } } } }
3、再在第778行处找到此段代码
//如果不用默认的sortrank或id排序,使用联合查询(数据量大时非常缓慢) if(preg_match('/hot|click|lastpost|weight/', $orderby))
并添加红色部分内容。
4、标签调用:
{dede:list orderby='weight' orderway='asc'}
这样{dede:list}标签就支持了按权重排序的调用,并且动静态状态下测试均成功!
dede:arclist修改方法
1、在织梦系统中找到以下目录/include/taglib/arclist.lib.php
文件;
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,并修改
//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 asc"; //插入这句 从小到大 else $ordersql = " ORDER BY arc.sortrank $orderWay";
然后用orderby='weight' 来进行调用
