织梦DedeCms5.7全站按TAG和关键字调用相关文章方法

文章作者:网友投稿 发布时间:2012-10-23 来源:网络

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.veryhuo.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

按关键词关连文章的标签

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

使用前记得使用emeditoreditplusdreamweaver之类的编辑器把数据库前缀批量改成你自己的,一般默认是dede_,本文中是veryhuo_前缀。
