dedecms织梦tag keyword怎么调用相关文章

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

推荐学习：织梦cms

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)
{
    global $dsql;
      
    //属性处理
    $attlist="row|12,titlelen|30,infolen|250,col|1,tablewidth|100,mytypeid|0,byabs|0,imgwidth|1,imgheight|90,flag|";
    FillAttsDefault($ctag->CAttribute->Items,$attlist);
    extract($ctag->CAttribute->Items, EXTR_SKIP);
    $revalue = &#39;&#39;;
      
    if(empty($tablewidth)) $tablewidth = 100;

    $tablewidth = $tablewidth."%";
    $colWidth = $colWidth."%";
$orwheres = &#39;&#39;;
