DedeCMS一個SEO優(yōu)化重要標(biāo)簽likearticle，根據(jù)標(biāo)題、關(guān)鍵字調(diào)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(guān)鍵詞”的文章，內(nèi)容相關(guān)度增強，為網(wǎng)站增加PV。缺點是不能調(diào)用全站相似文章，不支持order by排序?qū)傩�，做如下修改�?/p>

likearticle全站調(diào)用相似文章

       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 ";

likearticle支持order by排序

       繼續(xù)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(shè)置排序則按照權(quán)重先排序
else $orderquery = " order by arc.sortrank $orderWay";
