如何限制在WordPress中获取哪些标签

function restrict_tags_for_role($allowed_tags, $tag_class, $tag_name){
    $restricted_tags = array('restricted_tag1', 'restricted_tag2'); // 定义需要限制的标签
    $user = wp_get_current_user();
    if (in_array('subscriber', $user->roles) && in_array($tag_name, $restricted_tags)) {
        return false; // 如果用户角色是subscriber且标签在限制列表中，则返回false，禁止获取该标签
    }
    return $allowed_tags;
}
add_filter('map_meta_cap', 'restrict_tags_for_role', 10, 3);

function restrict_tags_for_subscriber($caps, $cap, $user_id, $args){
    if ($cap === 'edit_post_tags') {
        $caps[] = 'do_not_allow'; // 如果是编辑标签的权限，则设置为do_not_allow，禁止获取标签
    }
    return $caps;
}
add_filter('user_has_cap', 'restrict_tags_for_subscriber', 10, 4);
