谢谢Milo. 之前没有考虑在我的函数中添加register\\u post\\u类型，因为我认为它会干扰我在CPT UI中创建的现有自定义post类型，结果证明它很有用，并且会覆盖CPT UI post类型。

我使用了相同的slug，它自动将数据连接到手动创建的post类型。代码如下：

function create_post_type() {
register_post_type( \'office_post\', array(
  \'capability_type\' => \'post\',
  \'capabilities\' => array(
    \'create_posts\' => false, // Removes support for the "Add New" function ( use \'do_not_allow\' instead of false for multisite set ups )
  ), 
  \'labels\' => array(
    \'name\' => __( \'Office\' ),
    \'singular_name\' => __( \'Office\' )
  ),
  \'map_meta_cap\' => true, // Set to `false`, if users are not allowed to edit/delete existing posts
  \'public\' => true,
  \'menu_icon\' => \'http://architecture.com/testdrive/wp-content/uploads/2018/04/logo-white-e1524992076968.png\',
));
} 
add_action( \'init\', \'create_post_type\' );
