帝国cms按tag调用相关内容，数量不够调用最新文章的代码

帝国cms按tag调用相关内容，数量不够调用最新文章的代码。

1、根据tag调用相关的文章10条，不够调用最新文章

代码如下

function user_newslist($classid,$id,$num=10){
    
   global $empire,$dbtbpre,$class_r;
    
   $tbname=$class_r[$classid]['tbname'];
   $tr=$empire->fetch1("select tagid from {$dbtbpre}enewstagsdata where id=".$id." and classid=".$classid."");
if($tr){
   $sql="select * from {$dbtbpre}enewstagsdata  as a LEFT JOIN {$dbtbpre}ecms_{$tbname}  as b ON a.id=b.id where a.tagid={$tr[tagid]} and a.id<>{$id}  limit ".$num;
    $tsql=$empire->query($sql);
     while($tt=$empire->fetch($tsql)){
            
         $str.='<li> <a href="'.$tt[titleurl].'.html">'.$tt[title].'</a></li>';
         $num--;
     }
      
      
       
      $num=$num-$total;
       
    
    $sql2="select * from {$dbtbpre}ecms_{$tbname} limit ".$num;
    $tsql2=$empire->query($sql2);
     while($tt2=$empire->fetch($tsql2)){
      
            
         $str.='<li> <a href="'.$tt2[titleurl].'.html">'.$tt2[title].'</a></li>';
  
     }
      
}
   return $str;
}
