dedecms织梦tag keyword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

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

<?php
if(!defined('DEDEINC')) exit('Request Error!');
function lib_liketags(&$ctag,&$refObj)
{
    global $dsql;
     
    //属性处理
    $attlist="row|12,titlelen|30,infolen|250,col|1,tablewidth|100,mytypeid|0,byabs|0,imgwidth|1,imgheight|90,flag|";
    FillAttsDefault($ctag->CAttribute->Items,$attlist);
    extract($ctag->CAttribute->Items, EXTR_SKIP);
    $revaluehttp://www.cppcns.com/cms/dedecms/= '';
     
    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)."' ";
$dsql->Execute('me', "Select * From `dede_tagindex` where $getsql ");
while($arow = $dsql->GetArray('me'))
{
$tids[] = $arow['id'];
}
$tid = join(',', $tids);
if($tid!='')
{
061
$dsql->Execute("me", "Select aid From `dede_taglist` where tid in($tid) And arcrank > -1 group by aid order by aid desc");
while($arow = $dsql->GetArray("me"))
{
$ids[] = $arow['aid'];
$arcid =  $refObj->Fields['aid'];
}
}
}
if($eregtype == 'tag' && count($ids) == 0 )
{
return;
}
else
{
if(count($ids) > 0)
{
if(!empty($typeid))
{
$typeid = " And arc.typeid in($typeid) And arc.id<>$arcid ";
}
$idsStr = join(',', $ids);
$query = "Select arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault,tp.defaultname,tp.namerule,
