$delivery->comments_buro()->create([
'name' => auth()->user()->firstname,
'user_id' => auth()->user()->id,
'message' => $request['repair_report_buro'],
'icon' => 'fa fa-commenting-o',
'style' => $position->style,
]);
Thanks for help.

Answer 1

You need Laravel Validations for that. Please read this: https://laravel.com/docs/5.8/validation
For example:
//controller
public function index(Request $request)
{
$validator = Validator::make($request->all(), [
'message' => 'required|string',
]);
if ($validator->fails()) {
//do validation error handling here
}
// create new row in database.
}

I have a right code. It works with it. I close this question. The right code is:
if(isset($request['repair_report_buro']) && !empty($request['repair_report_buro'])){
$delivery->comments_buro()->create([
'name' => auth()->user()->firstname,
'user_id' => auth()->user()->id,
'message' => $request['repair_report_buro'],
'icon' => 'fa fa-commenting-o',
'style' => $position->style,
]);
}
