dedecms织梦tag keyword怎么调用相关文章？

DEDE官方的dede:likearticle是利用文章中输入的关键词或者自动分词形成的关键词来关联文章，但是有时候自动生成的关键词并不精确，造成关联不准，这里我们通过自定义一个类库文件来实现精准获取相关文章

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)

在 \include\taglib\ 下添加一个liketags.lib.php 代码如下

<?php
if(!defined(&#39;DEDEINC&#39;)) exit(&#39;Request Error!&#39;);
function lib_liketags(&$ctag,&$refObj)

    FillAttsDefault($ctag->CAttribute->Items,$attlist);
