我在下面有一张注册表格，用于在大会上注册用户。注册有 4 种不同的场景。所以注册表单需要处理这 4 种不同的场景。但它不工作，只有场景 1 工作正常。

你知道如何实现这种场景吗？

场景 1:(唯一运行良好的场景)

• 大会有两种门票类型“门票类型1”和“门票类型2”
• 工单类型“tt1”有一个自定义问题关联“Whats your phone?”，工单类型“tt2”没有任何关联的自定义问题
• 所有参与者是“1”，这意味着有必要收集每个参与者的信息(姓名和姓氏)
• 此场景的图表:

场景 2:

• 大会有“tt1”和“tt2”两种门票类型
• 工单类型“tt1”和“tt2”没有关联任何自定义问题
• all participants为“1”表示需要收集每个参与者的信息
• 此场景的图表:

场景 3:

• 大会有“tt1”和“tt2”两种门票类型
• 工单类型“tt1”有一个自定义问题关联“Whats your phone?”，工单类型“tt2”没有任何关联的自定义问题
• 所有参与者为“0”，表示不需要收集每个参与者的信息(姓名)
• 此场景的图表:

场景 4:

• 大会有“tt1”和“tt2”两种门票类型
• 工单类型“tt1”和“tt2”没有关联任何自定义问题
• 所有参与者为“0”，表示不需要收集每个参与者的信息(姓名)
• 此场景的图表:

在变量“$selectedTypes”中可以找到上一页中选择的门票

最佳答案

我看到两件事

1.- 当 $allParticipants == 0 时，表单不发送任何内容，可能更像是:

    <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>

                   @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[]"/>

                   @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>

                                @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.- 问题似乎取决于工单类型并且是可选的，函数应该考虑到它。

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);
}

希望有用! 问候
