試してみるとエラーが発生し、グーグルを精査すると、私はこの作業を行うことができました。
まず、これはクラス内で、add_meta_boxのコールバックには元の文字列ではなくarray ($this, <cb>)
形式が必要です。
第二に、代わりにadd_meta_boxes
アクション・コールバックを使用しての、register_post_type
ための引数は、私は以下のようなものを使用し、独自のオプションを持っている:'register_meta_box_cb' => array($this, 'initialize_federation_post_type')
だから、仕事にそれを取得し、取得するためにコードのビットに追加した後、表示モードで表示するフィールドは、次のようになります。
