laravelのauthでテンプレートへデータを渡す方法を知りたい

Question

authで、register.blade.phpにデータを渡したいのですが、showRegistrationFormアクションがなく、やり方がわかりません。ご教授お願いします。

下記の$aをregister.blade.phpに渡したいです

public function showRegistrationFrom()
    {
        $a = [1,2,3,4]
        return view('~~~', ['a' => $a]);
    }

php artisan route:list

            'password' => Hash::make($data['password']),
        ]);
    }
}

追記
php artisan make:authコマンドで追加されたApp\Http\Controllers\Auth\RegisterController@showRegistrationForm
があって、RegisterControllerのshowRegistrationFormアクションにテンプレートへ送るデータを追加したいのですが、
showRegistrationFormアクションが見つけられません。どうやって送ればいいのでしょうか？

ファイルのクラス名、routes/web.phpは？

[sk2938]

Auth::routes();　
です。

[退会済みユーザー]

それ、聞いてないです。
showRegistrationFrom() はどこに書いたメソッド？？？
web.phpについては聴き方を変えます。
php artisan route:list の結果貼ってください。

[sk2938]

showRegistrationFrom()は書いてなくて、
App\Http\Controllers\Auth\RegisterController@showRegistrationForm
に$aのデータを入れたいと言う意味です。

[退会済みユーザー]

ここじゃなくて、「質問」に追記してください。

[sk2938]

了解です

[退会済みユーザー]

「showRegistrationFrom()は書いてなくて」とはどういう意味？
書かれているからroute:listで表示されているわけですが。

[sk2938]

showRegistrationFrom()は自分で書いたのではなく、authコマンドでおそらく追加されました。なのでRegisterController.phpを確認してみて、showRegistrationFromアクションを探してみたのですが、見つからず困っている状況です。

回答したのは気付いてます？

[sk2938]

はい、調べているところです。

Answer 1

私も同じことを実現したいと思っています。
この記事が役に立ちそうです。

以下で、書かれているようで、オーバーライドが必要とのことです。

use Illuminate\Foundation\Auth\RegistersUsers

Answer 2

showRegistrationFormアクションが見つけられません。

APIドキュメントを開き、左上の検索フォームで「showRegistrationForm」を検索します。
