I have a congress registration page that has the form below that the user should fill to register in the congress. In this registration form:
If "all_participants" column is "1" in the congress table, it appears for each selected ticket in the previous page (congress details page) a section for the user that is doing the registration insert the name and surname of each participant (that is, associating each selected ticket in the previous page to a participant name and surname)
If the all_participants column is "0", it appears the "
<p>Is not necessary additional info.</p>" because is not necessary to collect info of each participant (for each selected ticket). The registration is done using the information of the authenticated user.the selected tickets from the previous page are available in the variable "
$selectedTypes"
// registration form in the registration.blade.php page
<form method="post" id="step1form" action=""> {{csrf_field()}} @if (!empty($allParticipants)) @if($allParticipants == 1) <p>Please fill in all fields. Your tickets will be sent to p{{ (\Auth::check()) ?

The first scenario is working fine, Im getting issues in the scenario 2 and 3.
Scenario 1 is working fine: "all_participants" column is "1" in the congresses table which means that is necessary to collect info of each participant and the user selected in the previous page (congress details page) 1 or more ticket types that have asociated one or more custom questions. This is the only scenario that is working fine. Diagram demonstrating the scenario:
This is working fine. The registrations and participants table stay like:
Registration table
id congress_id main_participant_id 1 1 1 (user 1 registers in the congress with id 1) Participants table
id registration_id ticket_type_id name surname 1 1 1 John X 2 1 2 Jake Y Answers table
id participant_id question_id answer 1 1 1 000 Questions table
id question congress_id answer 1 Whats your phone? 1 000 Scenario 2 is not working fine The scenario 2 is If all_participants is "1" and the user select ticket types that dont have any no custom questions associated. In this scenario Im getting this error below because "$request->participant_question_required" dont exist:
"Invalid argument supplied for foreach()" in ... else { $messages = [ 'participant_question.*.required' => 'The participant is required' ]; foreach ($request->participant_question_required as $key => $value) { ... I can put "if(isset($request->participant_question_required)) {" and then all code inside of this, but like that if the congress dont have any custom question associated then dont appears any error but no record are inserted in the registrations and participants table.
Diagram of the scenario 2 to demonstrate the issue:
Scenario 3 is not working fine: If all_participants is "0" and the user select ticket types that have 1 or more custom questions associated, in the registartion form dont appears any custom question. But if there are custom questions for some ticket type selected by the user and "all_participant" is "0" which means that is only necessary to collect info from the user that is doing the registration (the authenticated user) it shoud appear the custom question(s) associated to the selected ticket type(s) for the user that is doing the registration to answer.
Diagram of the scenario 3 to demonstrate the issue:

If you wish to store more than one ticket_type to a participant you will need to use a pivot table. A pivot table is a table that only contains ids and relates data together in a many to many fashion.
e.g.
participants_ticket_type table id ticket_type_id participant_id 1 1 2 2 2 2 Notice how participant 2 has ticket_types of 1 and 2? This is a many to many relationship.
Laravel handles these relationships for you and you can find it in their docs. https://laravel.com/docs/5.6/eloquent-relationships#many-to-many
Usually if you find yourself storing more than 1 id in a column a many to many relationship will solve this issue.

I see two things
1.- The form doesn't send anything when $allParticipants == 0, maybe something more like:
<form method="post" id="step1form" action=""> {{csrf_field()}} @if (!is_null($allParticipants) && is_int($allParticipants)) @if($allParticipants == 1) <p>Please fill in all fields. Your tickets will be sent to p{{ (\Auth::check()) ? Auth::user()->email : old('email')}}.</p> @else <p>Its not necessary aditional info. Your tickets will be sent to {{ (\Auth::check()) ? Auth::user()->email : old('email')}}.</p> @endif @foreach($selectedTypes as $selectedType) @foreach(range(1,$selectedType['quantity']) as $test) <h6>Participant - 1 - {{$test}}</h6> <div class="form-check"> <input class="form-check-input" type="radio" name="payment_method" value="referencias"> <label class="form-check-label d-flex align-items-center" for="exampleRadios1"> <span class="mr-auto">Fill the following fields with the authenticated user information.</span> </label> </div> @if($allParticipants == 1) <div class="form-group font-size-sm"> <label for="participant_name" class="text-gray">Name</label> <input type="text" name="participant_name[]" required class="form-control" value=""> </div> <div class="form-group font-size-sm"> <label for="participant_surname" class="text-gray">Surname</label> <input type="text" required class="form-control" name="participant_surname[]" value=""> </div> @foreach($selectedType['questions'] as $customQuestion) <div class="form-group"> <label for="participant_question">{{$customQuestion->question}}</label> <input type="text" @if($customQuestion->pivot->required == "1") required @endif class="form-control" name="participant_question[]"> <input type="hidden" name="participant_question_required[]" value="{{ $customQuestion->pivot->required }}"> <input type="hidden" value="{{ $customQuestion->id }}" name="participant_question_id[]"/> </div> @endforeach @else <input type="hidden" value="foo" name="participant_name[]"/> <input type="hidden" value="bar" name="participant_surname[]"/> @endif <input type="hidden" name="ttypes[]" value="{{ $selectedType['id'] }}"/> @endforeach @if ($allParticipants == 0) @foreach($selectedType['questions'] as $customQuestion) <div class="form-group"> <label for="participant_question">{{$customQuestion->question}}</label> <input type="text" @if($customQuestion->pivot->required == "1") required @endif class="form-control" name="participant_question[]"> <input type="hidden" name="participant_question_required[]" value="{{ $customQuestion->pivot->required }}"> <input type="hidden" value="{{ $customQuestion->id }}" name="participant_question_id[]"/> </div> @endforeach @endif @endforeach @endif <input type="submit" href="#step2" id="goToStep2Free" class="btn btn-primary btn float-right next-step" value="Go to step 2"/> </form> 2.- Questions seems to depend on Ticket types and are optionals, the function should take it into account.
public function StoreUserInfo(Request $request, $id, $slug = null, Validator $validator){ $allParticipants = Congress::where('id', $id)->first()->all_participants; $user = Auth::user(); $rules = []; $messages = []; if(isset($request->participant_question_required)) { $messages = [ 'participant_question.*.required' => 'The participant is required' ]; foreach ($request->participant_question_required as $key => $value) { $rule = 'string|max:255'; // I think string should come before max //dd($value); // if this was required, ie 1, prepend "required|" to the rule if ($value) { $rule = 'required|' . $rule; } // add the individual rule for this array key to the $rules array $rules["participant_question.{$key}"] = $rule; } } if($allParticipants){ $rules = [ 'participant_name.*' => 'required|max:255|string', 'participant_surname.*' => 'required|max:255|string', ]; } $validator = Validator::make($request->all(), $rules, $messages); if($validator->passes()) { $registration = Registration::create([ 'congress_id' => $id, 'main_participant_id' => $user->id, 'status' => 'C', ]); $participants = []; for ($i = 0; $i < count($request->participant_name); $i++) { $name = ($allParticipants) ? $request->participant_name[$i] : ''; $surname = ($allParticipants) ? $request->participant_surname[$i] : ''; $participants[] = Participant::create([ 'name' => $name, 'surname' => $surname, 'registration_id' => $registration->id, 'ticket_type_id' => $request->rtypes[$i] ]); } if (isset($request->participant_question)) for ($i = 0; $i < count($request->participant_question); $i++) $answer = Answer::create([ 'question_id' => $request->participant_question_id[$i], 'participant_id' => $participants[$i]->id, 'answer' => $request->participant_question[$i], ]); } return response()->json([ 'success' => true, 'message' => 'success' ], 200); } Hope it works!

First of all use select * from TABLENAME and then use the COUNT function either in the query Or use PHP Count function on the laravel blade file then execute your code..
on blade file
@if(count($records)>0){ // Your Code }
