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('DEDEINC')) exit('Request Error!'); function lib_liketags(&$ctag,&$refObj) {     global $dsql;            //属性处理     $attlist="row|12,titlelen|30,infolen|250,col|1,tablewidth|100,mytypeid|0,byabs|0,imgwidth|1,imgheight|90,flag|";     FillAttsDefault($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);     $tablewidth = $tablewidth."%";     $colWidth = $colWidth."%"; $orwheres = ''; if($flag != '') { $flags = explode(',', $flag); for($i=0; isset($flags[$i]); $i++) $orwheres .= " AND FIND_IN_SET('{$flags[$i]}', arc.flag)>0 "; }        $ids = array();     $tids = array();            if(!empty($refObj->Fields['tags'])) {         $keyword = $refObj->Fields['tags'];     }     else {         $keyword = ( !empty($refObj->Fields['keywords']) ? $refObj->Fields['keywords'] : '' );     }            $typeid = ( !empty($mytypeid) ? $mytypeid : 0 );     if(empty($typeid))     {         if(!empty($refObj->Typelink->TypeInfos['reid'])) {              $typeid = $refObj->Typelink->TypeInfos['reid'];         }         else {              if(!empty($refObj->Fields['typeid'])) $typeid = $refObj->Fields['typeid'];         }     }            if( !empty($typeid) && !preg_match('#,#', $typeid) ) {         $typeid = GetSonIds($typeid);     }        if(!empty($refObj->Fields['tags']) && $eregtype != 'keyword' ) { $tags = explode(',', addslashes($refObj->Fields['tags'])); $getsql = " tag like '".join("' OR tag like '", $tags)."'

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 class="list-img"> <img src="[field:litpic/]" alt="[field:title/]"/> </div> <div class="list-info"> <p class="title">[field:title/]</p> <p class="meta">[field:description /]</p> </div> </a> </li> {/dede:liketags}
