dedecms5.7内容页面如何调用相关文章

1 ，找到include/taglib/likearticle.lib.php，将里面的代码全部复制为：

<?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

2 然后在你的模板页面调用：

{dede:likearticle row='5' titlelen='50' eregtype=all|tag|keyword}

<li>. <a href="[field:arcurl/]" target="_blank">[field:title/]</a><span>[field:pubdate function="GetDateMK(@me)"/]</span></li>

{/dede:likearticle}

最后更新文档就显示出来5条相关的内容。
