织梦DedeCms5.7全站按TAG和关键字调用相关文章方法，可单用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。

1. 把下边代码保存到文章模版的适当位置

<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>

{/dede:likearticle}

ul>

dd>

dl>

div>

2.把下边的php代码替换掉include/taglib/likearticle.lib里的代码

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
