如何在同一个 controller (laravel) 中的函数之间传递变量？

Question

im new to laravel and this is the first time i use stackoverflow so forgive me if i made some mistakes. i need to pass $newOrder to the view(orders.success) in order to be able to print the "receipt" once the order is concluded. Nothing seems to work, i have tried with compact/with methods but it's always undefined since $newOrder is declared in another function. do you have some tips?

            Mail::to($email)->send(new PaymentConfirmationMail());
            return view('orders.success');
        }


        return view('orders.braintree', ['token' => $clientToken]);
    }

    public function success(Request $request)
    {
        return view('orders.success');
    }
}

Answer 1

Try this

Mail::to($email)->send(new PaymentConfirmationMail());
return view('orders.success',['newOrder' => $newOrder]);

Or change params on success function like this

public function success($newOrder)
{
    return view('orders.success', ['newOrder' => $newOrder]);
}

And return from previews function

Mail::to($email)->send(new PaymentConfirmationMail());
return $this->success($newOrder);
