Laravel でデータの受け渡し

Last updated at Posted at 2018-06-04

次のページを参考にしました。
データの受け渡し

完成すると次のような表示がされます。
laravel_jun0502.png

  1. プロジェクトの用意
  2. laravel new sample_project
    cd sample_project
    php artisan make:controller HelloController
    

    新規に作成しないで、こちらで作成したプログラムを改造することもできます。
    Laravel で HelloWorld

  3. app/Http/Controllers/HelloController.php の編集
  4. app/Http/Controllers/HelloController.php
    <?php
    
    namespace App\Http\Controllers;
    
    use Illuminate\Http\Request;
    
    class HelloController extends Controller
    {
        //
      public function index()
      {
        // 配列の初期化
        $data = array();
    
        // データ格納
        $data['name'] = '鈴木';
        $data['message'] = 'こんにちは';
    
        // 現在日時
    	date_default_timezone_set('Asia/Tokyo');
    	$data['today'] = date('Y年m月d日 H:i:s');
    
        return view('hello', $data);
      }
    }
    
  5. resources/views/hello.blade.php の作成
  6. resources/views/hello.blade.php
    <!DOCTYPE html>
    <html lang="ja">
    <head>
      <meta charset="UTF-8">
      <title>My First Page</title>
    </head>
    <body>
      <p>{{$name}}さん</p>
      <p>{{$message}}</p>
      <p>現在は {{$today}} です</p>
    <p>Jun/05/2018</p>
    </body>
    </html>
    
  7. routes/web.php の編集
  8. 最後に一行を加えます。

    routes/web.php
    <?php
    
    /*
    |--------------------------------------------------------------------------
    | Web Routes
    |--------------------------------------------------------------------------
    |
    | Here is where you can register web routes for your application. These
    | routes are loaded by the RouteServiceProvider within a group which
    | contains the "web" middleware group. Now create something great!
    |
    */
    
    Route::get('/', function () {
        return view('welcome');
    });
    
    Route::get('hello', 'App\Http\Controllers\HelloController@index');
    
  9. サーバーを動かします。
  10. php artisan serve --host 0.0.0.0
    

    ブラウザーで、 http://localhost:8000/hello にアクセスします。

    冒頭の画面が表示されます。

次の環境で確認しました。
