dedecms织梦tag+keyword调用相关文章

2023/03/11 12:21 创新屋收录网已浏览350次

官方的dede:likearticle并没有那么精准的输出相关文章，下面我们自定义一个类库文件来实现精准获取相关文章

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

在 includetaglib 下添加一个liketags.lib.php 代码如下

    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);

    }
