我想了解与自定义帖子类型的关系。

我使用此代码注册帖子类型

add_action(\'init\', function(){

$args = array(
  \'public\'             => true,
  \'query_var\'          => true,
  \'rewrite\'            => array( \'slug\' => \'/\' ),
  \'supports\'           => array( \'title\', \'excerpt\'),
  \'query_var\'          => true,
  \'label\'              => \'Series\'
);
register_post_type(\'series\', $args);

$args = array(
  \'public\'             => true,
  \'query_var\'          => true,
  \'rewrite\'            => array( \'slug\' => \'%series%\', \'with_front\' => false ),
  \'supports\'           => array( \'title\', \'excerpt\'),
  \'query_var\'          => true,
  \'label\'              => \'Episode\'
);

register_post_type(\'episodes\', $args);

});

我有一个名为《权力的游戏》的意甲联赛，就是这样

我该怎么做？谢谢你，很抱歉我的英语不好：）

add_filter(\'post_type_link\', function($link, $post){
    if ($post->post_type != \'episode\')
        return $link;
    if ($cats = get_post_meta($post->ID, \'serie_slug\', true))
        $link = str_replace(\'%serie%\', $cats, $link);
    return $link;
}, 10, 2);

add_action(\'init\', function(){

$args = array(
  .
  .
  \'rewrite\'            => array( \'slug\' => \'series\' ),
  .
  .
);
register_post_type(\'series\', $args);

$args = array(
  .
  .
  \'rewrite\'            => array( \'slug\' => \'series/%series%\', \'with_front\' 
  .
  .
);

register_post_type(\'episodes\', $args);

flush_rewrite_rules();

});
