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,支持直接输出自定义字段,支持flag文章属性,非常适合SEO  
eregtype='all|tag|keyword',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 文件代码如下  
<?phpif(!defined('DEDEINC')) exit('Request Error!');function lib_liketags(&$ctag,&$refObj){ 
 
global $dsql,$envs; 
 
//属性处理 
 
$attlist="row|12,titlelen|30,infolen|250,col|1,tablewidth|100,typeid|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'] : '' ); 

$typeid = ( !empty($typeid) ? $typeid : 0 ); 
if(empty($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!=''){$dsql->Execute("me", "Select aid From `dede_taglist` where tid in($tid) And arcrank > -1 group by aid order by aid desc");while($arow = $dsql->GetArray("me")){$ids[] = $arow['aid'];$arcid =
