下面大家来看看织梦使用tag调用相关文章的办法，非常适合seo哦。也可以根据关键词+tag调用。

1.把下边代码保存到文章模版的适当位置

<!– //相关文章代码开始 –>
<div class=”xgwz”>
<dl class=”tbox”>
<dt><strong>相关文章</strong></dt>
<dd>
<ul class=”c1 ico2″>
{dede:likearticle col=’2′ row=’10’ titlelen=’42’ eregtype=all|tag|keyword}
<li><a href=”[field:arcurl/]”>[field:title/]</a></li>

2.把下边的php代码替换掉likearticle.lib里的代码  dedecms.com

<?php
if(!defined(‘DEDEINC’)) exit(‘Request Error!’);
/*————————————–
按关键词关连文章的标签
eregtype属性
eregtype = keyword 只匹配关键字
eregtype = tag 只匹配tag
eregtype = all tag优先，不存在tag则匹配关键字
mytypeid=” 栏目ID,多个栏目用,隔开
—————————————*/
function lib_likearticle(&$ctag,&$refObj)
{
global $dsql;

//属性处理
$attlist=”row|12,titlelen|28,infolen|150,col|1,tablewidth|100,mytypeid|0,byabs|0,imgwidth|120,imgheight|90″;
FillAttsDefault($ctag->CAttribute->Items,$attlist);
extract($ctag->CAttribute->Items, EXTR_SKIP);
$revalue = ”;

if(empty($tablewidth)) $tablewidth = 100;
if(empty($col)) $col = 1;
$colWidth = ceil(100/$col); 内容来自dedecms
$tablewidth = $tablewidth.”%”;
$colWidth = $colWidth.”%”;

$ids = array();
$tids = array();

$typeid = ( !empty($mytypeid) ? $mytypeid : 0 );
if(empty($typeid))
{
if(!empty($refObj->Typelink->TypeInfos[‘reid’])) {
$typeid = $refObj->Typelink->TypeInfos[‘reid’];
}
else {
if(!empty($refObj->Fields[‘typeid’])) $typeid = $refObj->Fields[‘typeid’];
}
}

if( !empty($typeid) && !ereg(‘,’, $typeid) ) {
$typeid = GetSonIds($typeid);
}
if(!empty($refObj->Fields[‘tags’]) && $eregtype != ‘keyword’ )
{
$tags = explode(‘,’, addslashes($refObj->Fields[‘tags’]));

• 1.用于5.6、5.7的任何版本

2.可以单用tag来调用相关文章，也可用tag+keyword来调用相关文章（默认tag优先于keyword，可以自己排序），非常适合SEO，经测试效果极佳。
