是的，您可以使用wp_get_object_terms 筛选以从使用默认WordPress方法的任何列表中删除隐藏类别，如wp_get_post_categories().

add_filter(\'wp_get_object_terms\', \'wpse_remove_unwanted_category\', 10, 4);
function wpse_remove_unwanted_category($terms, $object_ids, $taxonomies, $args) {
    // we\'re only interested in category, if this is another taxonomy
    if ($args[\'taxonomy\'] !== \'category\') {
        // return early
        return $terms;
    }

    // 34 and 1509 are ids of categories we want to remove
    $remove_categories = array(34, 1509);
    $filtered_terms = array_filter($terms, function($term) use ($remove_categories) {
        // if term_id is in the array, filter it out (aka remove from array)
        return ( ! in_array($term->term_id, $remove_categories));
    });
    return $filtered_terms;
}
