我正在嘗試在Laravel中執行Flash消息,現在這些Flash消息在沒有複選框的頁面上適用於成功消息和錯誤消息。Laravel Flash錯誤 - 如何檢查複選框是否被選中?
我有一個名爲'deleteappointmentform'的視圖,它要求用戶選中一個複選框,並刪除所選的約會,但是如果我沒有選中任何複選框並單擊提交,它會給我一個成功消息,而不會實際檢查他們是否已勾選和複選框。我試圖得到它顯示一個錯誤信息,如果他們不檢查任何複選框
任何幫助的感謝,謝謝
這是與刪除約會
function deleteAppointment(Request $request)
{
Appointment::destroy($request->appointments);
Session::flash('successCancelAppointment', 'Appointment cancelled successfully!');
return redirect('all');
}
此交易的功能是我的消息刀片
@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
這是我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
那做工精良,三江源,請您能否簡要解釋代碼的規則和驗證部分是幹什麼的? – TF120
