dedecms利用tag调用相关文章

作者: jiukeshuju 分类: DEDECMS 发布时间: 2020-10-02 14:28


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  

<!– //相关文章代码开始 –>
<div class=”xgwz”> 
     <dl class=”tbox”> 
           <dt><strong>相关文章</strong></dt> 
               <dd> 
                  <ul class=”c1 ico2″> 
                       {dede:likearticle col=’2′ row=’10’ titlelen=’42’ eregtype=all|tag|keyword} 
                             <li><a href=”[field:arcurl/]”>[field:title/]</a></li>

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

 
<?php
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
—————————————*/
function lib_likearticle(&$ctag,&$refObj)
{
 global $dsql;
 
 //属性处理
 $attlist=”row|12,titlelen|28,infolen|150,col|1,tablewidth|100,mytypeid|0,byabs|0,imgwidth|120,imgheight|90″;
 FillAttsDefault($ctag->CAttribute->Items,$attlist);
 extract($ctag->CAttribute->Items, EXTR_SKIP);
 $revalue = ”;
 
 if(empty($tablewidth)) $tablewidth = 100;
 if(empty($col)) $col = 1;
 $colWidth = ceil(100/$col); 内容来自dedecms 
 $tablewidth = $tablewidth.”%”;
 $colWidth = $colWidth.”%”;
 
 $ids = array();
 $tids = array();
 
 $typeid = ( !empty($mytypeid) ? $mytypeid : 0 );
 if(empty($typeid))
 {
   if(!empty($refObj->Typelink->TypeInfos[‘reid’])) {
     $typeid = $refObj->Typelink->TypeInfos[‘reid’];
   }
   else {
     if(!empty($refObj->Fields[‘typeid’])) $typeid = $refObj->Fields[‘typeid’];

    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。
