php - 存储注册状态不正常(始终存储值 "C"，但如果注册已支付，则应存储 "I")

标签 php laravel

我在 session 注册页面中有一个表格，供用户在 session 中注册该表格具有以下操作:

<form method="post" action="{{route('conferences.storeRegistration', ['id' => $id, 'slug' => $slug])}}">
...
</form>

一个 session 可以有一种或多种注册类型，注册类型可以是免费的也可以是付费的。根据用户选择的注册类型，提交表单时，在此 storeRegistration() 中，我想在注册表的状态列中存储值“C”(完整) 如果所选注册类型的总价为“0”，但如果为“>0”，我想存储为“I”(不完整)。

对于 storeRegistrationInfo() 中的那个，我试图在 session “总计”中获取值，然后使用三元“状态”=> ($total > 0)？ 'I' : 'C',' 如下所示:

 public function storeRegistration(Request $request, $id, $slug = null, Validator $validator)
    {
    ...
    $total = Session::get('total');

    if ($validator->passes()) {
        $registration = Registration::create([
            'conference_id' => $id,
            'main_participant_id' => $user->id,
             'status' => ($total > 0) ? 'I' : 'C',
        ]);

    ...
}

但它不起作用，总是存储在“状态”列中的值 C'，独立于注册是否已支付门票或所有门票都是免费的。问题应该是因为 dd($total) 显示“null”。

您知道如何正确实现这一点吗？

问题的顺序流:

我有一个 session 详细信息页面，用户可以在其中以表格形式选择他想要的 session 门票数量。一场 session 可以关联一张或多张票，有些票可以免费，也可以付费。所以在这个表单中，用户可以选择他想要的票，然后单击“下一步”。表单具有此操作:

<form method="post" action="{{route('conferences.storeQuantities', ['id' => $conference->id, 'slug' => $conference->slug])}}">
...
</form>

因此，当用户单击“下一步”时，代码转到 RegistrationController storeQuantities() 此方法存储所选票证(每张票的数量、总数等)和 session 中的一些其他信息，并将用户返回到'conferences.registration' 路线:

public function storeQuantities(Request $request, $id, $slug = null)
    {

        $request->validate([
            'rtypes' => ['required', 'array', new RegistrationTypeQuantity],
        ]);

        $rtypeQuantities = $request->get('rtypes');

        $allParticipants = Conference::where('id', $id)->first()->all_participants;

        $total = 0;
        foreach ($rtypeQuantities as $rtypeName => $quantity) {

            if ($quantity) {

                $rtype = RegistrationType::where('name', $rtypeName)->firstOrFail();
                $price = $rtype->price;

                $selectedRtypes[$rtype->name]['quantity'] = $quantity;
                $selectedRtypes[$rtype->name]['price'] = $price;
                $selectedRtypes[$rtype->name]['subtotal'] = $price * $quantity;
                $total += $selectedRtypes[$rtype->name]['subtotal'];
                $selectedRtypes[$rtype->name]['total'] = $total;

                $selectedRtypes[$rtype->name]['questions'] = $rtype->questions;
                $selectedRtypes[$rtype->name]['id'] = $rtype->id;
            }
        }
        Session::put('selectedRtypes', $selectedRtypes);
        Session::put('allParticipants', $allParticipants);
        Session::put('customQuestions', $selectedRtypes[$rtype->name]['questions']);
        Session::put('total', $total);

        return redirect(route('conferences.registration', ['id' => $id, 'slug' => $slug]))->with('total', $total);
    }

然后代码转到路由:

Route::get('/conference/{id}/{slug?}/registration', [
    'uses' => 'RegistrationController@displayRegistrationPage',
    'as'   =>'conferences.registration'
]);

然后函数 displayRegistrationPage 被调用，它获取 session 中的值并将用户重定向到注册页面:

  public function displayRegistrationPage(Request $request, $id, $slug = null)
    {

        $selectedRtypes = Session::get('selectedRtypes');
        $allParticipants = Session::get('allParticipants');
        $customQuestions = Session::get('customQuestions');




        if (isset($selectedRtypes)) {
            return view('conferences.registration',
                ['selectedRtypes' => $selectedRtypes, 'allParticipants' => $allParticipants, 'customQuestions' => $customQuestions, 'id' => $id,
                    'slug' => $slug]);
        } else {
            return redirect(route('conferences.show', ['id' => $id, 'slug' => $slug]));
        }
    }

现在注册页面呈现给用户。这里有一个用户注册表格，介绍一些数据以在 session 中注册。表单具有此操作:

<form method="post" action="{{route('conferences.storeRegistration', ['id' => $id, 'slug' => $slug])}}">
...
</form>

因此，当提交表单时，如果用户正在进行的注册只有免费注册类型，那么在这个 storeRegistration() 中，我想在注册表的状态列中存储值“C”(完成)。但我想存储值“I”(不完整)，如果有 1 种或多种注册类型，则价格 > 0。因为用户随后需要付款，所以注册在他付款之前保持不完整。

 public function storeRegistration(Request $request, $id, $slug = null, Validator $validator)
    {
    ...
    $total = Session::get('total');

    if ($validator->passes()) {
        $registration = Registration::create([
            'conference_id' => $id,
            'main_participant_id' => $user->id,
                'status' => ($total > 0) ? 'I' : 'C',
        ]);
        ...
    ...
}

完整注册 Controller :

class RegistrationController extends Controller
{


    // handles the form of the conference details page where the user select the tickets
    public function storeQuantities(Request $request, $id, $slug = null)
    {

        $request->validate([
            'rtypes' => ['required', 'array', new RegistrationTypeQuantity],
        ]);

        $rtypeQuantities = $request->get('rtypes');


        $allParticipants = Conference::where('id', $id)->first()->all_participants;


        $total = 0;
        foreach ($rtypeQuantities as $rtypeName => $quantity) {

            if ($quantity) {

                $rtype = RegistrationType::where('name', $rtypeName)->firstOrFail();

                $price = $rtype->price;

                $selectedRtypes[$rtype->name]['quantity'] = $quantity;
                $selectedRtypes[$rtype->name]['price'] = $price;
                $selectedRtypes[$rtype->name]['subtotal'] = $price * $quantity;
                $total += $selectedRtypes[$rtype->name]['subtotal'];
                $selectedRtypes[$rtype->name]['total'] = $total;

                $selectedRtypes[$rtype->name]['questions'] = $rtype->questions;
                $selectedRtypes[$rtype->name]['id'] = $rtype->id;
            }
        }


        Session::put('selectedRtypes', $selectedRtypes);
        Session::put('allParticipants', $allParticipants);
        Session::put('customQuestions', $selectedRtypes[$rtype->name]['questions']);
        Session::put('total', $total);

        return redirect(route('conferences.registration', ['id' => $id, 'slug' => $slug]))->with('total', $total);
    }

    // redirects the user to the registration page
    public function displayRegistrationPage(Request $request, $id, $slug = null)
    {

        $selectedRtypes = Session::get('selectedRtypes');
        $allParticipants = Session::get('allParticipants');
        $customQuestions = Session::get('customQuestions');


        if (isset($selectedRtypes)) {
            return view('conferences.registration',
                ['selectedRtypes' => $selectedRtypes, 'allParticipants' => $allParticipants, 'customQuestions' => $customQuestions, 'id' => $id,
                    'slug' => $slug]);
        } else {

            }

            return redirect(route('user.index', ['user' => Auth::id()]).'#myTickets');

        }
    }
}

最佳答案

你的问题在这里:

return redirect(route('conferences.registration', ['id' => $id, 'slug' => $slug]))->with('total', $total);

您已经以永久方式将数据存储到 session 中，但就在您想要重定向时，您删除了第一个存储的数据:

Session::put('total', $total);

与:

...->with('total', $total);

最后一个，仅将数据闪入您的 session 以供下一个请求(当您显示注册表时)，因此当您发送注册表以供提交时，“总计”数据已经从 session 中消失。

删除:

...->with('total', $total);

这对你来说没问题。
