Laravel 5.2驗證錯誤未出現在刀片上

我想在驗證錯誤的同時在查看頁面中給出無效輸入。但錯誤消息沒有出現在視圖頁面中。如果可能的話請有人提供解決方案。Laravel 5.2驗證錯誤未出現在刀片上

這裏是控制器：

public function saveStudent(Request $request){ 
     $this->validate($request,[ 
      'name' => 'required|max:120', 
      'email' => 'required|email|unique:users', 
      'phone' => 'required|min:11|numeric', 
      'course_id'=>'required' 
      ]); 

     $user = new User(); 
     $user->name= $request->Input(['name']); 
     $user->email= $request->Input(['email']); 
     $user->phone= $request->Input(['phone']); 
     $user->date = date('Y-m-d'); 
     $user->completed_status = '0'; 
     $user->course_id=$request->Input(['course_id']); 
     $user->save(); 
     return redirect('success'); 
    }

下面是這個視圖頁面：

<html> 
    <head> 
     <title> Create Course </title> 

    <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">

    <body> 

     <div class="container" > 

      <h3> Student Register </h3> 
     {!! Form::open(array('route' => 'saveUser','class'=>'form-horizontal','method'=>'POST')) !!}

     <div class="form-group">

      <select class="form-control input-sm" name="course_id" > 
      @foreach($input as $row) 
      <option value="{{$row->id}}">{{$row->name}}</option> 
      @endforeach 
      </select> 
      </div> 
     <button type="submit" class="btn btn-default">Submit</button> 
    {!! Form::close() !!} 
     </div> 
    @if(count($errors)>0) 
    <div class="alert alert-danger"> 
     <strong>Whoops!</strong> Enter Valid Input</br> 
     <ul> 
     @foreach($errors->all() as $error) 
     <li>{{$error}}</li> 
     @endforeach 
     </ul> 
    </div> 
    @endif 
    </body> 
</html>

你換用「你的路由網絡'中間件組？ – Sovon

是的！它只位於網絡中間件的中間！ – User57

修改您的函數，如下面的例子：

public function saveStudent(Request $request){ 
      $rules = [ 
      'name' => 'required|max:120', 
      'email' => 'required|email|unique:users', 
      'phone' => 'required|min:11|numeric', 
      'course_id'=>'required' 
      ]; 

     $validator = Validator::make($request->all(),$rules); 
     if($validator->fails()) 
     { 
      return redirect()->route('your route here'))->withErrors($validator)->withInput(); 
     }else{ 

     $user = new User(); 
     $user->name= $request->Input(['name']); 
     $user->email= $request->Input(['email']); 
     $user->phone= $request->Input(['phone']); 
     $user->date = date('Y-m-d'); 
     $user->completed_status = '0'; 
     $user->course_id=$request->Input(['course_id']); 
     $user->save(); 
     return redirect('success'); 
     } 
    }
