如何在laravel 5的刀片模板上顯示錯誤消息

Question

我是由laravel 5.2創建的項目。我一直在創建登錄頁面，但我被卡在顯示刀片模板上的驗證錯誤消息。我不知道我做錯了什麼？

請幫我解決這個問題。謝謝！

查看

<div> 
    <input type="text" name="email" class="form-control" placeholder="Email"/> 
    @if($errors->has('email')) <p>{{ $errors->first('email') }}</p> @endif 
</div> 

控制器

<?php 

namespace App\Http\Controllers; 

use Illuminate\Http\Request; 
use App\Http\Controllers\Controller; 
use App\User; 
use Illuminate\Support\Facades\Validator; 
use Illuminate\Support\Facades\Input; 
use Illuminate\Support\Facades\Redirect; 
use Illuminate\Support\MessageBag; 


class AuthController extends Controller 
{ 
    public function login() 
    { 
     return view('user.login'); 
    } 

    /** 
    * Show the form for creating a new resource. 
    * 
    * @return \Illuminate\Http\Response 
    */ 
    public function handlelogin(Request $request) 
    { 
     $messages = array(
      'email.required'=>'You cant leave Email field empty', 
      'password.required'=>'You cant leave name field empty' 
     ); 

     $rules = array(
      'email' => 'required|email|max:20', 
      'password' => 'required' 
     ); 

     $validator = Validator::make($request->all(),$rules,$messages); 

     if ($validator->fails()) 
     { 
      return redirect()->back()->withErrors($validator->errors()); 

     }else{ 

      $data = $request->only('email','password'); 


      if(\Auth::attempt($data)){ 
       return redirect()->intended('/'); 
      } 

     return back()->withInput(); 
     } 
    } 


}

你並不需要檢查錯誤，只是做如下

{!! $errors->first('email', '<dev class="error-block">:message</div>') !!} 

請注意，「錯誤塊「是一個自定義的CSS類，你可以根據自定義HTML模板 你的選擇。
