在后台magento中隐藏和跳过发货、付款方式

我想

隐藏以执行以下操作 和跳过航运，支付方式在magento的后端 我试过了 覆盖“Mage/Adminhtml/controllers/Sales/Order/CreateController.php” 使用默认装运和付款方式值的saveaction，如下所示：

public function saveAction()
    {
      try {
            $this->_processData();
            if ($paymentData = $this->getRequest()->getPost('payment')) {
                $this->_getOrderCreateModel()->setPaymentData($paymentData);
                $this->_getOrderCreateModel()->getQuote()->getPayment()->addData($paymentData);
            }

            $order = $this->_getOrderCreateModel()
                ->importPostData($this->getRequest()->getPost('order'))
//------------edit start
                    ->setPaymentMethod('checkmo')
                    ->setShippingMethod('freeshipping_freeshipping')
//------------edit end
                ->createOrder();

            $this->_getSession()->clear();
            Mage::getSingleton('adminhtml/session')->addSuccess($this->__('The order has been created.'));
            $this->_redirect('*/sales_order/view', array('order_id' => $order->getId()));
        }
        catch (Mage_Core_Exception $e){
            $message = $e->getMessage();
            if( !empty($message) ) {
                $this->_getSession()->addError($message);
            }
            $this->_redirect('*/*/');
        }
        catch (Exception $e){
            $this->_getSession()->addException($e, $this->__('Order saving error: %s', $e->getMessage()));
            $this->_redirect('*/*/');
        }
    }

伟大的那么，到目前为止您尝试了什么？您想为后端中的所有用户隐藏吗？还是要隐藏以确定用户？
