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 includetaglib 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|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)."'
