验证后挂钩未重定向到表单页面

Question

I'm building a small validator for my form with laravel 7 and i needed a custom logic to be added after the standard validation so I used the after validation hook as in doc . My issue is not with the logic of the controller but the fact that after the validation occur and I add the custom error message i don't get redirected to the original form. What I'm missing?

public function store(Request $request)
    {
        //
        $data = $request->all();
        $newSpn = new Sponsorization;
        $userId = Auth::id();
        $paymentPlanId = $data["payment_plan_id"];
        $apartmentId = $data["apartment_id"];
        $payPlanInfo = PaymentPlan::find($paymentPlanId)->hours_duration;
        $alreadyActive = $this->alreadyActive($apartmentId);

        $userApartment = DB::table('apartments')
                            ->where('user_id', $userId)
                            ->pluck('id');

        $validator = Validator::make($request->all(),[
            'payment_plan_id' => "required",
            'appartment_id' => [
                'required',
                Rule::in($userApartment)
            ]
        ]);

        $validator->after(function ($validator) use ($alreadyActive){
            if ($alreadyActive) {
                $validator->errors()->add('apartment_promo', 'A promo is already active on this apartment!');
        }
    });


    if ($validator->fails()) {
        //
    }

    $newSpn->apartment_id = $apartmentId;
    $newSpn->payment_plan_id = $paymentPlanId;
    $newSpn->start_date = date("Y-m-d H:m:s");
    $newSpn->end_date = date("Y-m-d H:m:s",strtotime("+{$payPlanInfo} hours"));

    $newSpn->save();
}

You can redirect back to the page where you come from like this

if ($validator->fails()) {
    return redirect()->route('name.of.route.where.you.come.from')
        ->withErrors($validator)
        ->withInput();
}

As you want to be redirect to the orignal form you must define that behaviour when the validation failed so you can pass the validation errors and old input values calling the method withErrors and withInput
