Custom payment method Error

simo.kassab

Dears,

I successfully created a new payment method, and the controller has 2 methods (redirect and transaction)

redirect method: am getting the amount and sending data away to an external URL, this URL will redirect me to the method transaction if successful,

Am getting success from the payment method, but in transaction, method am doing this:

use Illuminate\Http\Request;
use Braintree\Gateway as Braintree_Gateway;
use Braintree_Transaction;
use Webkul\Sales\Repositories\InvoiceRepository;
use Webkul\Sales\Repositories\OrderRepository;
use Webkul\Checkout\Facades\Cart;
use App\Exceptions\Handler;
use Firebase\JWT\JWT; 
public function transaction(Request $request) {
$secret = core()->getConfigData('sales.paymentmethods.zaincash.zaincash_secret');
        $result= JWT::decode($request->token, $secret, array('HS256'));
        $result= (array) $result;
        print_r($result);
       
        if($result['status']=='success') {

            $order = $this->orderRepository->create(\Cart::prepareDataForOrder());

            $this->order = $this->orderRepository->findOneWhere([
                'cart_id' => Cart::getCart()->id
                ]);

            $this->orderRepository->update(['status' => 'processing'], $this->order->id);

            Cart::deActivateCart();

            session()->flash('order', $order);

            $this->invoiceRepository->create($this->prepareInvoiceData());

            session()->flash('success', trans('dcb::app.payment-successfull'));

        }
         $response="success";
         return $response;
}

am getting this error : "message": "Call to a member function toArray() on null", on this line:

$order = $this->orderRepository->create(\Cart::prepareDataForOrder());

Why the Cart facade is empty here, even I got the amount in the first method (redirect) like this:

$cartAmount = \Cart::getCart()->grand_total;

Thanks

Hi @simo-kassab,

Cart::deActivateCart() has been called. Please check your controller and methods. This issue seems to be the wrong code implementation.

Please check your codes.

Hi @devansh-webkul

Even if I only put this in my method am getting an error

Controller:

public function transaction(Request $request)
    {
        echo Cart::getCart()->id;
    }

am getting this error:

Hi @simo-kassab,

Your cart is empty thats why you are not getting the data. Please check your controller somewhere your cart gets deactivated.

hi @devansh-webkul,

I sent you my controller, there is no cat deactivation anywhere please check it, I did the same thing for Braintree and another payment method and it's working fine.

Please help

devansh-webkul

Hi @simo-kassab,

From there I am not getting just check line by line by adding die and dump somewhere there is a small mistake nothing else.

simo.kassab

dear @devansh-webkul ,

When I pay as a guest, it works fine and without error, but when I sign in, it's not reading the cart object
