FrontController::$context is protected property when create a order

[miumax]

in My module I'm try to make a order from cart. 

in my modules controller file I'm calling validateOrder

 PaymentModule::validateOrder((int)$urbCart->id, $order_status, $order_total, "urb-it", NULL, array(), (int)$currency->id, false, $urbCart->secure_key); 

 

for create a order. Hove ever I got below error.
PHP Fatal error:  Cannot access protected property UrbitOrderCompleteModuleFrontController::$context in /opt/webapp/urbit/classes/PaymentModule.php on line 171


The payment module error is happen in (line 171) is below

if (!isset($this->context)) {

            $this->context = Context::getContext();

        }

 

Why that context is say as protected property ? How can I create order ?

the validateOrder function is not a static function, so you cannot use it like PaymentModule::validateOrder

 

instead, you do this

$this->module->validateOrder(.....)
