Why does the payment gateway fail to process payments?
Given this snippet from a WordPress payment gateway plugin, why does the payment not process correctly? function process_payment($order_id) { $order = wc_get_order($order_id); $result = $this->send_request_to_gateway($order); if ($result == 'success') { $order->update_status('completed'); return array('result' => 'success', 'redirect' => $this->get_return_url($order)); } return array('result' => 'fail'); } Options:
Wordpress
function process_payment($order_id) {
  $order = wc_get_order($order_id);
  $result = $this->send_request_to_gateway($order);
  if ($result == 'success') {
    $order->update_status('completed');
    return array('result' => 'success', 'redirect' => $this->get_return_url($order));
  }
  return array('result' => 'fail');
}
AThe update_status method is called before payment confirmation from the gateway.
BThe send_request_to_gateway method returns a string, but the code expects a boolean.
CThe function does not call $order->payment_complete() to finalize the payment.
DThe get_return_url method is missing a required parameter.
