  @endsection

控制器：

   public function showLoginForm()
   {
    return view('auth.login',[
        'title' => 'Login',
        'loginRoute' => 'login',
        'forgotPasswordRoute' => 'password.request',
    ]);
   }

路线：

  Route::get('/login','LoginController@showLoginForm')->name('login');

Answer 1

首先，您需要了解传递的是会话还是变量

请尝试以下代码，

  function countDate(){

    var ss = SpreadsheetApp.openByUrl(url);
    var ws = ss.getSheetByName("Test_Data");
    var dateRg = ws.getRange(1, 9, ws.getLastRow(), 1).getValues();

    for (var i =1; i < dateRg.length; i++){
      var dateTest = dateRg[i];

      if (dateTest > 5){
         ws.getRange(2,4).setValue(dateTest);
    }
  }

刀片中的用途

public function showLoginForm()
{
    $title = 'Login Page';
    $pageData = [
        'title'               => 'Login',
        'loginRoute'          => 'login',
        'forgotPasswordRoute' => route('password.request'),
    ];
    return view('auth.login',compact('pageData','title');
}

之后，运行以下命令

{{ $pageData['title'] }} // Login

{{ $title }} // Login

Answer 2

尝试使用其他名称：

public function showLoginForm()
   {
    return view('auth.login')->with([
        'page_title' => 'Login',
        'loginRoute' => 'login',
        'forgotPasswordRoute' => 'password.request',
    ]);
   }

您认为：

{{ $page_title ? $page_title :'No Title Found' }}

未定义的变量：标题（视图：resources \ views \ auth \ login.blade.php）
