织梦CMS利用tag调用相关文章-PB模板网

下面大家来看看织梦使用tag调用相关文章的办法，非常适合seo哦。也可以根据关键词+tag调用。

1.把下边代码保存到文章模版的适当位置

相关文章

[field:title/]

2.把下边的php代码替换掉likearticle.lib里的代码 dedecms.com

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
---------------------------------------*/

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。
