嘿，伙计们，我有这个函数，我需要排除两个类别：81和82。你能帮忙吗？：）

代码

function has_related_same_cat_posts(){
global $post;
$categories = get_the_category($post->ID);

if ($categories) {
    $category_ids = array();
    foreach($categories as $individual_category) 
        $category_ids[] = $individual_category->term_id;

    $args=array(
    \'category__in\' => $category_ids,
    \'post__not_in\' => array($post->ID),
    \'posts_per_page\'=> 4, // Number of related posts that will be shown.
    \'caller_get_posts\'=>1,
    \'orderby\' => \'rand\',
    
    );

    $my_query = new wp_query( $args );
    if( $my_query->have_posts() ) {
        $return = true;
    } else {
        $return = false;
    }
    
}

return $return;
}
