dedecms织梦tag keyword调用相关文章

时间:2019-09-10 17:00:01  来源:admin  作者:猎凡网络

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

 

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

 

<?phpif(!defined('DEDEINC')) exit('Request Error!');function lib_liketags(&$ctag,&$refObj){    global $dsql;        //属性处理    $attlist="row|12,titlelen|30,infolen|250,col|1,tablewidth|100,mytypeid|0,byabs|0,imgwidth|120,imgheight|90,flag|";    FillAttsDefault($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)."'
