请检查show_in_menu 和show_ui 的参数register_post_type 在注册tham之前，请键入您的帖子。

有时，这可能是由于menu_position 与另一个菜单位置冲突，或者可能被其他插件隐藏。尝试更改该值。

\'menu_position\' => 21

嗨，我有一些想法添加我也创建自定义帖子类型你需要自定义帖子类型你遵循这个代码这对我来说很有用。

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

}
add_action( \'init\', \'create_services_cpt\', 0 );

这是一个非常古老的问题；A但我只是通过确保register_post_type 在操作“init”的回调中调用，而不是“admin\\u init”。

我在想，既然我只希望我的CPT维护对管理员可见，那么我应该在admin\\u init上进行设置。我认为正确的方法是在“init”上生成CPT仪表板菜单，为了限制可见性，请使用功能。也就是说，在CPT上设置功能，并向分配给用户的角色添加功能。看到这个了吗other SE Q&A 关于这个话题。

您不想使用is\\u admin来避免注册码。更有可能的是，应该始终为所有用户定义CPT，而我们只是想限制特定用户的可见性和维护权限（通过他们的功能）。
