Php wordpress中的相关公文包查询

我使用wordpress 3.8.1，想展示5个相关的公文包，但我不知道如何查询。 我注册投资组合的代码是

}我终于找到了答案

$args=array(  
              'tag__in' => $tag_ids,  
              'post__not_in' => array($post->ID),  
              'showposts'=>3,  // Number of related posts that will be shown.  
              'post_type'=> 'portfolio'  
              );  

              $my_query = new wp_query($args);  

最好的

$args=array(  
              'tag__in' => $tag_ids,  
              'post__not_in' => array($post->ID),  
              'showposts'=>3,  // Number of related posts that will be shown.  
              'post_type'=> 'portfolio'  
              );  

              $my_query = new wp_query($args);
