Laravel Flash errors - How to check if a checkbox is checked? - laravel

Question

I'm trying to do flash messages in Laravel, now the flash messages work for success messages and error messages on pages that don't have checkboxes.
I have a view called 'deleteappointmentform' which requires the user to check a checkbox and it deletes the checked appointments, however if I don't check any checkbox and click submit it gives me a success message without actually checking if they've checked and checkboxes. I'm trying to get it to display an error message if they don't check any checkboxes
Any help's appreciated, thanks
This is the function that deals with deleting appointments
function deleteAppointment(Request $request)
{
Appointment::destroy($request->appointments);
Session::flash('successCancelAppointment', 'Appointment cancelled successfully!');
return redirect('all');
}
This is my messages blade
#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
This is my 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

you can try this
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');
}
