织梦DedeCms5.7全站按TAG和关键字调用相关文章方法

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

Copy to ClipboardLiehuo.Net Codes引用的内容：[www.dede58.com]
 
 
相关文章
 
 
 
{dede:likearticle col='2' row='10' titlelen='42' eregtype=all|tag|keyword} 
[field:title/]
 
{/dede:likearticle} 
 
 
 

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

Copy to Clipboard引用的内容：[www.dede58.com] if(!defined('DEDEINC')) exit('Request Error!');
