Question

我尝试使用jQuery anad AJAX创建一个多步骤表单。但是，当＆＃34;转到步骤2＆＃34;点击：

jquery.min.js:4 POST http://store.test/product/1/product-test/payment/storeUserInfo 500 (Internal Server Error)

此外，当点击网络标签然后点击＆＃34; storeUserInfo＆＃34;看来：

exception
:
"Illuminate\Contracts\Container\BindingResolutionException"
file
:
"/Users/jakeB/projects/store/vendor/laravel/framework/src/Illuminate/Container/Container.php"
line
:
933
message
:
"Unresolvable dependency resolving [Parameter #1 [ <required> array $data ]] in class Illuminate\Validation\Validator"

你知道错误在哪里吗？

在PaymentController中有storeUserInfo（）方法，它是步骤1的方法：

public function storeUserInfo(Request $request, $id, $slug = null, Validator $validator){
        $validator = Validator::make($request->all(),[
            'buyer_name' => 'required|max:255|string',
            'buyer_surname' => 'required|max:255|string',
            'buyer_email' => 'required|max:255|string',
            'name_invoice' => 'required|max:255|string',
            'country_invoice' => 'required|max:255|string',
        ]);

        if ($validator->fails()) {

            if($request->ajax())
            {
                return response('test');
            }

            $this->throwValidationException(

                $request, $validator
            );
        }
    }

路线：

Route::post('/product/{id}/{slug?}/payment/storeUserInfo', [
    'uses' => 'PaymentController@storeUserInfo',
    'as'   =>'products.storeUserInfo'
]);

//步骤1和步骤2 html

在PaymentController中使用Validator facade类

use Validator;

class PaymentController extends Controller
{

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

        $validator = Validator::make($request->all(),[
            'buyer_name' => 'required|max:255|string',
            'buyer_surname' => 'required|max:255|string',
            'buyer_email' => 'required|max:255|string',
            'name_invoice' => 'required|max:255|string',
            'country_invoice' => 'required|max:255|string',
        ]);

        if ($validator->fails()) {

            if($request->ajax())
            {
                return response('test');
            }

            $this->throwValidationException(

                $request, $validator
            );
        }
   }

}
