我试图建立一个像在图像中一样的上下文。

因此，对于图像的“screen 1”，我有一个与此路径关联的“single.blade.php”文件：

// Route for congress details page:
Route::get('/congress/{id}/{slug?}', [
    'uses' => 'FrontController@show',
    'as'   =>'congresses.show'
]);

 <select name="types[{{ $type->name }}]">

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

Route::post('/congress/{id}/{slug?}/registration', [
    'uses' => 'RegistrationController@storeQuantity',
    'as'   =>'congresses.storeQuantities'
]);

class RegistrationController extends Controller

 public function storeQuantity(Request $request, $id, $slug=null){
        $typeQuantities = $request->get('types');

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

        $total = 0;
        foreach($typeQuantities as $typeName => $quantity){

            $type = TicketType::where('name', $typeName)->firstOrFail();
            $price = $type->price;

            $customQuestionsOfTicketType = $type->questions;

            $selectedTypes[$type->name]['quantity'] = $quantity;
            $selectedTypes[$type->name]['price'] = $price;
            $selectedTypes[$type->name]['subtotal'] = $price * $quantity;
            $total+=  $selectedTypes[$type->name]['subtotal'];
            $selectedTypes[$type->name]['total'] = $total;
        }

        Session::put('selectedTypes', $selectedTypes);
        Session::put('allParticipants' , $allParticipants);
        Session::put('customQuestionsOfTicketType' , $customQuestionsOfTicketType);
        return redirect(route('congresses.registration',['id' => $id, 'slug' => $slug]));
    }

    public function displayRegistrationPage(Request $request, $id, $slug=null){
         $selectedTypes = Session::get('selectedTypes');
         $allParticipants = Session::get('allParticipants');
        return view('congresses.registration', ['selectedTypes' => $selectedTypes, 'allParticipants' => $allParticipants]);
}

}

1 to many between congress and registration (a congress can have many registrations)
1 to many between registration and participants (a registration can have man participants)
1 to many between congress and ticket types (a congress can have many ticket types)
1 to many between ticket types and ticket_type_questions (a ticket type can have many custom questions)
1 to many between questions and ticket_type_questions (a question can be associated with many ticket types)


// TicketType Model
class TicketType extends Model
{
    protected $fillable = [
        'name', '...', 'congress_id'
    ];

    public function congress(){
        return $this->belongsTo('App\Congress');
    }

    public function questions(){
        return $this->belongsToMany('App\Question', 'ticket_type_questions');

// Question Model

    public function ticket_types(){
        return $this->belongsToMany('App\TicketType', 'ticket_type_questions');
    }
}

最佳答案

问：有了这个代码，所有类型的票都会出现国会存在的自定义问题。但自定义问题只应出现在与该自定义问题相关联的票证类型中；
鉴于

public function storeQuantity(Request $request, $id){
    ...
    $customQuestionsOfTicketType = $type->questions;
    ...
}

$selectedTpyes[$type->name]['questions'] = $type->questions;

关于php - 如何更好地构造此上下文，并为每个选定的票证类型显示与该票证类型关联的自定义字段？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49764128/
