Laravel, can only flash error messages within controller? - php

Question

I'm using this to flash error messages within my UserController (using Toastr);
public function update(Request $request)
{
$validator = Validator::make($request->all(), [
'name' => 'required|max:200',
'email' => 'required|email|unique:users,email,'. Auth::id(),
'phone' => 'alpha_num|nullable|min:8',
]);
if ($validator->fails()) {
Toastr::error('Changes not saved', 'Error');
return back();
}
$user = Auth::user();
$user->name = $request->input('name');
$user->email = $request->input('email');
$user->phone = $request->input('phone');
$user->save();
Toastr::success('Changes saved', 'OK');
return back();
}
I would like to use Form Request for my validation, but keep running into problems when trying to flash (toastr) error messages.
Do one of you have an example of toastr used with Form Request? I have read the documentation like 10 times, but can't find a solution :(
https://laravel.com/docs/5.7/validation
This used to work about a year ago, but not anymore:
# Error messages
protected function formatErrors(Validator $validator)
{
$messages = $validator->messages();
foreach ($messages->all() as $message)
{
Toastr::error($message, 'Fejl');
}
return $validator->errors()->all();
}

Answer 1

Use withValidator() in your form request
but I am using toaster package from yoeunes/toastr
public function withValidator($validator)
{
$messages = $validator->messages();
foreach ($messages->all() as $message)
{
toastr()->error ( $message, 'Error');
}
return $validator->errors()->all();
}
It works for me in Laravel 7.x
Try that, thanks!
