织梦dedecms怎么使用tag+keyword调用相关文章

本文介绍了织梦dedecms怎么使用tag+keyword调用相关文章，解决办法：打开这个文件liketags.lib.php，将教程里面的代码放到里面，然后在前台模板调用新的代码就可以了。

织梦dedecms怎么使用tag+keyword调用相关文章？官方的dede:likearticle并没有那么精准的输出相关文章，下面我们自定义一个类库文件来实现精准获取相关文章。

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

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

<?phpif(!defined('DEDEINC')) exit('Request Error!');function lib_liketags(&$ctag,&$refObj){

global $dsql;

//属性处理

$attlist="row|12,titlelen|30,infolen|250,col|1,tablewidth|100,mytypeid|0,byabs|0,imgwidth|120,imgheight|90,flag|";

extract($ctag->CAttribute->Items, EXTR_SKIP);

if(empty($tablewidth)) $tablewidth = 100;

$colWidth = $colWidth."%";

$orwheres = '';

前台模板调用

{dede:liketags row='3' mytypeid='6' eregtype='all|tag|keyword' titlelen='250' infolen='250'}

<li>

<a href="[field:arcurl/]" title="[field:title/]" target="_blank">

<div>

<img src="[field:litpic/]" alt="[field:title/]"/>

</div>

<div>

<p>[field:title/]</p>

<p>[field:description /]</p>

</div>

</a>

</li>

{/dede:liketags}

这样就可以了。
