要获取用户最新帖子（自定义帖子类型）的永久链接，请执行以下查询：

$latest = get_posts(array(
        \'author\' => $current_user->ID,
        \'orderby\' => \'date\',
        \'post_type\' => \'my_custom_post_type\',
        \'order\' => \'desc\',
        \'numberposts\' => 1,
    ));
    if( $latest ) {
      $url = get_permalink($latest[0]->ID);
    } else {
      // No posts
    }
