  • dedecms织梦tag keyword调用相关文章的代码

    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 includetaglib 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
    $attlist="row|12,titlelen|30,infolen|250,col|1,tablewidth|100,mytypeid|0,byabs|0,imgwidth|120,imgheight|90,flag|";
    FillAttsDefault($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'];
    }
