Question

我正在尝试在Laravel中执行flash消息，现在flash消息适用于没有复选框的页面上的成功消息和错误消息。

我有一个名为'deleteappointmentform'的视图，要求用户选中一个复选框并删除已选中的约会，但如果我没有选中任何复选框并单击提交，则会给我一条成功消息，而不会实际检查它们是否'检查和复选框。我试图让它显示错误信息，如果他们不检查任何复选框

感谢任何帮助，谢谢

这是处理删除约会的功能

function deleteAppointment(Request $request)
{
    Appointment::destroy($request->appointments);
    Session::flash('successCancelAppointment', 'Appointment cancelled successfully!');
return redirect('all');
}

这是我的消息刀片

@if (Session::has('successCancelAppointment'))

<div class="alert alert-success" role="alert">
    <strong>Success: </strong> {{Session::get('successCancelAppointment')}}
</div>
    @endif



@if (count($errors) > 0)

<div class="alert alert-danger" role="alert">
    <strong>Errors:</strong>
    <ul> 
    @foreach ($errors->all() as $error)
        <li>{{$error}}</li>
        @endforeach

    </ul>
</div>
@endif

这是我的deleteappointmentsblade

@extends('layouts.master')
@section('title', 'Cancel Appointment')
@section('content')

<form action="{{url('deleteappointment')}}" method="POST">
    {{ csrf_field() }}
     @foreach ($appointments as $appointment)
        <div>
            <label> {{$appointment->user->firstname}} {{$appointment->user->surname}}</label>
            <label>Has an appointment at: {{$appointment->time}}</label>
            <label>On: {{$appointment->date}}</label>
            <label>With Dr: {{$appointment->doctor->surname}}</label>

            <input type='checkbox' value='{{$appointment->id}}' name='appointments[]'/>
        </div>
    @endforeach
    <input type="submit" name="submitBtn" value="Cancel Appointments">
</form>


@endsection

你可以试试这个

function deleteAppointment(Request $request)
 {     $rules=array(
            'appointments'=>'required'
        );
      $validator = Validator::make($request->all(), $rules);
        if($validator->fails())
      {
         $messages = $validator->messages();
         $errors = $messages->all();
         return redirect()->back()->withErrors($errors);
      }
      Appointment::destroy($request->appointments);
   Session::flash('successCancelAppointment', 'Appointment cancelled 
      successfully!');
   return redirect('all');
}
