      dedecms織夢tag keyword調用相關文章

      時間:2019-01-29來源/作者:網站源碼庫 編輯:源碼庫 文章熱度:

      DEDE官方的dede:likearticle是利用文章中輸入的關鍵詞或者自動分詞形成的關鍵詞來關聯文章,但是有時候自動生成的關鍵詞并不精確,造成關聯不準,這里我們通過自定義一個類庫文件來實現精準獲取相關文章

      可以單用tag來調用相關文章,也可用tag+keyword來調用相關文章(默認tag優先于keyword,可以自己排序)

      在 \include\taglib\ 下添加一個liketags.lib.php 代碼如下

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