这种情况应该如何流动？(根据所选的付款方式,在哪里放置代码来处理付款？)

Question

我有一个多步骤表单供用户在会议中注册,所有步骤都在同一registration.blade.php页面,在步骤1和步骤2完成ajax请求以验证表单字段.

步骤是:

• Step1是收集一些关于用户的信息(名称和锡号)
• 第2步是收取付款方式(信用卡或参考)
• 第3步是付款
• 步骤4显示成功消息(此步骤仅在使用信用卡成功付款后显示,参考付款方式此步骤不显示,使用参考付款方式仅显示步骤1,2和3)

我怀疑是在第2步和第3步之间.

如果执行下面的代码需要所选的付款方式参考,那么会生成一些付款参考,然后在步骤3中向用户提供该参考.当用户付款时,系统会收到通知并应插入付款表中price,payment_method_id,registration_id和status(付费).

使用参考资料处理付款的代码:

    public function ReferencesCharge(Request $request)
        {
           $payment_info = [
        'name' => "user name",
        'email' => 'user email',
        'value' => 'registration total price',
        'id' => 'registration id',
    ];

    $newPayment = new Payment($payment_info);
    $reference = $newPayment->gererateReferences();

    //$reference returns an array with necessary codes to present to the user so he can pay

    // after generate references is necessary:
            // show in step 3 the generated references
            // insert an entry in the payments table when the system receives a notification from 3rd party service informing that the user did the payment

}

如果选择的支付是信用卡需要执行下面的代码的信用卡中扣款,并插在付款表后price,payment_method_id,registration_id和status(付费).然后应将用户重定向到步骤4以显示成功消息:

处理信用卡付款的代码:

public function creditCardCharge(Request $request)
    {
        Stripe::setApiKey(config('services.stripe.secret'));
        $source = $request->stripeToken;

        try{
            Charge::create([
                'currency' => 'eur',
                'amount' => 2500,
                'source' => $source,
            ]);
        }
        catch(\Exception $e){
            return response()->json(['status' => $e->getMessage()], 422);
        }

        // after charging the card with success:
            // insert an entry in the payments table 
            // redirect to success confirmation step to inform the user that payment was done with success 
    }

我的疑问是流程应该如何,应该放置使用引用处理付款的代码和使用信用卡处理付款的代码.所以有可能实现这种情况:

现在,我只是让步骤1和步骤2正常工作.为了处理step1和step2,我有了RegistrationController.在步骤1中,用户引入的信息使用ajax post请求验证if 的storeUserInfo()方法RegistrationController返回200用户转到step2.

在步骤2中,用户选择在"去到步骤3"的支付方法和点击次数也做一个AJAX请求到storePaymentMethods()的RegistrationController,如果用户选择的至少1付款方法来验证.我怀疑是在这个方法之后返回代码200的过程应该如何.

根据付款方式,必须运行上面的相应代码(生成付款参考的代码或代码以向信用卡收费).

因此,我怀疑如何根据控制器和方法组织此代码,在哪里放置应根据所选付款方式执行的代码.你知道如何实现这一目标吗？

也许一种方法可能类似于下面的方法,storePaymentMethods()但在这种方法中做一切似乎都不正确:

public function storePaymentMethods(Request $request){
       $request->validate([
            'payment_method' => 'required',
        ]);

        if($request->payment_method == "references"){
          // generate codes and present to the user that codes
        }
        else if($request->payment_method == "credit_card"){
          // show credit card inputs to the user
          // and process the credit card payment with stripe
        }



        return response()->json([
            'success' => true,
            'message' => 'success',
            'payment_method' => $request->payment_method,
        ], 200);
    }

我现在拥有的多步骤表单注册流程的完整摘要:

所以对于step1,有以下形式:

<div>
    <form method="post" id="step1form" action="">
        {{csrf_field()}}
        <!-- fields of the step 1-->
        <input type="submit" href="#step2" id="goToStep2" class="btn next-step" value="Go to step 2"/>
    </form>
</div>

step1图片更好地解释:

当用户点击"转到步骤2"按钮时,会发出ajax请求来验证数据,如果没有错误,则返回代码200,用户转到步骤2:

$('#goToStep2').on('click', function (event) {
    event.preventDefault();
    var custom_form = $("#" + page_form_id_step1);
    $.ajax({
        method: "POST",
        url: '{{ route('conferences.storeRegistrationInfo', compact('id','slug') ) }}',
        data: custom_form.serialize(),
        datatype: 'json',
        success: function (data, textStatus, jqXHR) {
            var $active = $('.nav-pills li a.active');
            nextTab($active);
        },
        error: function (data) {    
            // show errors
        }
    });
});

然后在ConferencesController中有teh storeRegistrationInfo()来处理上面的ajax请求:

public function storeRegistrationInfo(Request $request, $id, $slug = null, Validator $validator){  
    $rules = [];
    $messages = [];

    $rules["name_invoice"] = 'required|max:255|string';
    $rules["TIN_invoice"] = ['required', 'string', new ValidTIN()];

    $validator = Validator::make($request->all(), $rules, $messages);

    $errors = $validator->errors();
    $errors =  json_decode($errors);

    if($validator->fails()) {
        return response()->json([
            'success' => false,
            'errors' => $errors
        ], 422);
    }
    return response()->json([
        'success' => true,
        'message' => 'success'
    ], 200);
}

因此,如果返回代码200,则用户在step2form中:

<div>
    <form method="post" id="step2form" action="">
        {{csrf_field()}}
        <!-- fields of the step 2-->
         <input type="submit" href="#step3" id="goToStep3" class="btn next-step" value="Go to step 3"/>
    </form>
</div>

step2图片更好地解释:

当用户点击"转到步骤3"按钮时,会发出一个ajax请求来验证数据,如果没有错误,则返回代码200,用户转到步骤3,ajax请求:

$("#credit_card_section").hide();
$("#references_section").hide();

var page_form_id_step2 = "step2form";

    $('#goToStep3').on('click', function (event) {
        event.preventDefault();
        var custom_form = $("#" + page_form_id_step2);
        $.ajax({
            method: "POST",
            url: '{{ route('conferences.storePaymentMethods', compact('id','slug') ) }}',
            data: custom_form.serialize(),
            datatype: 'json',
            success: function (data, textStatus, jqXHR) {
                var result = data;
                if(result['payment_method'] == 'credit_card'){
                    $("#credit_card_section").show();
                    $("#references_section").hide();
                }else{
                    $("#references_section").show();
                    $("#credit_card_section").hide();
                }
                var $active = $('.nav-pills li a.active');
                nextTab($active);
            },
            error: function (data) {
               // show errors
            }
        });
    });

ConferenceController具有storePayment()来处理上面的ajax请求,它验证用户是否选择了支付方法,如果是,则返回代码200:

public function storePaymentMethods(Request $request){
       $request->validate([
            'payment_method' => 'required',
        ]);
        return response()->json([
            'success' => true,
            'message' => 'success',
            'payment_method' => $request->payment_method,
        ], 200);
    }

然后是step3 div.在step3 div中,根据上一步骤中选择的付款方式(信用卡或参考),div显示div #credit_card_section可见或#references_section可见:

<div>
    <form method="post" id="step3form" action="">
            {{csrf_field()}}
            <div id="credit_card_section">
                <!-- present necessary fields to
                payments with credit card-->
            </div>
              <div id="references_section">
        <!-- present generated reference to the user so he can pay-->
            </div>
    </form>
</div>

step3图像更好地解释,根据付款方式,步骤3中显示的信息是不同的.如果付款方式是信用卡step4,则在使用信用卡成功收费后,会出现显示成功消息的div:

然后在使用信用卡完成付款后,应该显示成功消息的第4步div:

<div id="step4">
   <p>
   <i class="fa fa-plus" aria-hidden="true"></i>
   Payment and registration completed with  success.
   </p>
</div>

//我现在拥有的RegistrationController方法的简历,RegistrationController是我处理多步形式的控制器

路线step1:

Route::post('/conference/{id}/{slug?}/registration/storeRegistrationInfo', [

路线step2:

Answer 1

正如您所怀疑的那样，为了更好地构建代码和分离逻辑（DRY 概念），您应该做几件事：

• 使用 3 个函数创建PaymentsController（首先，您肯定会在此处添加更多函数）

  1. 用于处理您的参考资料
  2. 用于处理信用卡
  3. 用于存储付款方式（在会话中存储付款方式，直到用户完成步骤3）

  对于如何命名这些函数，您完全自由，但我建议使用诸如processViaReferences,processViaCreditCard和 之类的名称storePaymentMethod。

  如果将它们分开，那么阅读和验证会更容易。

  为它们创建相应的帖子路由并在代码中适当引用。

• 创建仅包含您的表单的零件视图。

  然后包括这些零件视图，@include以使其在视图级别上分离。对于 javascript/jQuery 中的引用，请记住保留它们的正确 ID。如果您还没有这样做，您也可以将 javascript 提取到其他视图、部件视图或单独的 js 文件。

  您的视图/表单代码应该转到这些零件视图...
