Laravel 5.2 redirect（） - > back（） - > withErrors $ errorsが空です。

Question

私の認証フォームに検証を適用しようとしています。 redirect（） - > back（） - > withErrors（）がエラーをMessageBagに保存していないので、$ this-> sendFailedLoginResponse（$ request）に戻るまで、すべてがうまく動作します。私のビューでは変数が空です）。

laravel.blade.php

<!-- BEGIN LOGIN FORM --> 
     <form class="login-form" action="{{ url('/login') }}" method="post"> 
      {!! csrf_field() !!} 
      <h3 class="form-title font-green">Iniciar sesión</h3> 
       @if (count($errors) > 0) // Here is where i check and my $errors variable is empty 
        @foreach ($errors->all() as $error) 
         <div class="alert alert-danger"> 
          <button class="close" data-close="alert"></button> 
          <span>{{ $error }}</span>

こんにちはあなたは次のように記述する必要がいるリダイレクト（）

return redirect()->back()->with('status-keyword', 'error message'); 

とフロントエンドに、あなたは

@if (session('error')) 
    <div class="alert alert-danger text-center msg" id="error"> 
    <strong>{{ session('error') }}</strong> 
    </div> 
@endif 

を使用してそのメッセージを取得し、私はあなたに、この意志は実りを願っています。 ありがとうございます。
