任何帖子类型都可以在前端创建，但您需要编写表单和保存逻辑。

提交表单并在变量中准备好内容/标题等后，将其传递到此函数中

wp_insert_post( $post, $wp_error );

// Create post object
$my_post = array(
  \'post_title\'    => \'My post\',
  \'post_content\'  => \'This is my post.\',
  \'post_type\'     => \'post\',
  \'post_status\'   => \'publish\',
  \'post_author\'   => 1,
);

// Insert the post into the database
$new_post_id = wp_insert_post( $my_post );

要在后端隐藏它，请设置show_ui 调用时为falseregister_post_type
