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
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>
{/dede:likearticle}
</ul>
</dd>
</dl>
</div>
<!-- //相关文章代码结束 -->
2.把下边的php代码替换掉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
