OPC, skip choosing carrier

[redoli]

Hello everybody, I'm trying to skip carrier selection at One Page Checkout because we only have one carrier in my shop, I have made it but in 5 steps checkout, modifying OrderController and order-payment.tpl, but the point is the controller to be modified is OrderOPCcontroller, I think here it is the part of the code that has to be modified, but don't know how to do it, if anybody can give me a hand with this I will appreciate so much.

 

Kind Regards:

		
		Cart::addExtraCarriers($vars);
		
		$this->context->smarty->assign($vars);

		if (!Address::isCountryActiveById((int)($this->context->cart->id_address_delivery)) && $this->context->cart->id_address_delivery != 0)
			$this->errors[] = Tools::displayError('This address is not in a valid area.');
		elseif ((!Validate::isLoadedObject($address_delivery) || $address_delivery->deleted) && $this->context->cart->id_address_delivery != 0)
			$this->errors[] = Tools::displayError('This address is invalid.');
		else
		{
			$result = array(
				'HOOK_BEFORECARRIER' => Hook::exec('displayBeforeCarrier', array(
					'carriers' => $carriers,
					'delivery_option_list' => $this->context->cart->getDeliveryOptionList(),
					'delivery_option' => $this->context->cart->getDeliveryOption(null, true)
				)),
				'carrier_block' => $this->context->smarty->fetch(_PS_THEME_DIR_.'order-carrier.tpl')
			);

			Cart::addExtraCarriers($result);
			return $result;
		}
		if (count($this->errors))
			return array(
				'hasError' => true,
				'errors' => $this->errors,
				'carrier_block' => $this->context->smarty->fetch(_PS_THEME_DIR_.'order-carrier.tpl')
			);
	}
