CakePHP4のコンポーネントからコントローラーとリクエストを利用するメモ

Last updated at Posted at 2021-07-06

CakePHP4でコンポーネントからコントローラーとリクエストを呼び出せなくて、悩んだのでメモ

結論

以下のように書く。

class SampleComponent extends Component {

  private $controller;
  private $request;

  public function beforeFilter()
  {
      $this->controller = $this->getController();
      $this->request = $this->controller->getRequest();
  }
}

ちなみに以下は、ダメだった

class SampleComponent extends Component {

  private $controller;
  private $request;

  public function beforeFilter()
  {
      $this->controller = $this->getController();
      // Controllerクラスの$requestプロパティはproctedなので、アクセスできない
      $this->request = $this->controller->request;
  }
}

補足

公式ドキュメントには書いてなかったので、ちょっと苦労した、、

CakePHP4ので入っているRequestHandlerComponentのソースコードを読んだらわかった。ソースコードをちゃんと読むのは大切ですね。
