DedeCMS一個SEO優化重要標簽likearticle，根據標題、關鍵字調用本欄目下的相似文章。這意味著為某文章增加了許多帶“長尾關鍵詞”的文章，內容相關度增強，為網站增加PV。缺點是不能調用全站相似文章，不支持order by排序屬性，做如下修改：
打開/include/taglib/likearticle.lib.php，找到
$typeid = " And arc.typeid in($typeid) And arc.id<>$arcid "; |
修改為
$typeid = " And arc.id<>$arcid "; |
繼續找到
extract($ctag->CAttribute->Items, EXTR_SKIP);$revalue = "; |
下面添加
$orderby=$ctag->GetAtt('orderby'); |
找到
if( empty($arcid) || $byabs==0 ) {$orderquery = " order by arc.id desc ";}else {$orderquery = " order by ABS(arc.id – ".$arcid.") ";} |
修改為
$orderquery = ";if($orderby=='hot' || $orderby=='click') $orderquery = " order by arc.click $orderWay";else if($orderby == 'sortrank' || $orderby=='pubdate') $orderquery = " order by arc.sortrank $orderWay";else if($orderby == 'id') $orderquery = " order by arc.id $orderWay";else if($orderby == 'near') $orderquery = " order by ABS(arc.id – ".$arcid.")";else if($orderby == 'lastpost') $orderquery = " order by arc.lastpost $orderWay";else if($orderby == 'scores') $orderquery = " order by arc.scores $orderWay";else if($orderby == 'rand') $orderquery = " order by rand()";else if($orderby == 'weight') $orderquery = " order by arc.weight asc";//如果沒有特定設置排序則按照權重先排序else $orderquery = " order by arc.sortrank $orderWay"; |
