在Magento销售订单视图中显示订单评论作者的姓名

我创建了一个自定义模块，允许在Magento前端提交订单评论Sales_Guest_View

我能够在前端上显示评论作者的姓名，但我还需要在Sales_Order_View的管理面板中显示该名称。

原因是在Magento管理中跟踪订单评论等。

下面是显示作者名称

<?php
require_once Mage::getModuleDir('Controller', 'Mage_Sales') . DS . 'Controller' . DS . 'Abstract.php';
class Tamedo_FrontendOrderMessage_FormController extends Mage_Sales_Controller_Abstract {
    protected $_guest_cookieName  = 'guest-view';
    protected $_guest_lifeTime    = 600;
    public function orderAction() {
        if(Mage::getSingleton('customer/session')->isLoggedIn()) {
            $this->_loadValidOrder();
        } else {
            Mage::helper('sales/guest')->loadValidOrder();
        }
        $order = Mage::registry('current_order');
        $orderId = $order->getId();
        if(empty($orderId)) {
            if (Mage::getSingleton('customer/session')->isLoggedIn()) {
                $this->_redirect('sales/order/history');
            } else {
                $this->_redirect('sales/guest/form');
            }
        } else {
            $data = $this->getRequest()->getParams();
            if (!empty($data['history']['comment']))
                $append = " Posted By: ".$username.""; {
                $order->addStatusHistoryComment($data['history']['comment'], false)
                        ->setIsVisibleOnFront(true)
                        ->setIsCustomerNotified(false);
                $order->save();
            }
            if (Mage::getSingleton('customer/session')->isLoggedIn()) {
                $this->_redirect('sales/order/view', array('order_id' => $order->getId()));
            } else {
                $toCookie = base64_encode($order->getProtectCode());
                Mage::getSingleton('core/cookie')->set($this->_guest_cookieName, $toCookie, $this->_guest_lifeTime, '/');
                $this->_redirect('sales/guest/view');
            }
        }
    }
}

和Admin Controller，它只显示提交评论的Admin的名字

                $this->loadLayout('empty');
                $this->renderLayout();
            }
            catch (Mage_Core_Exception $e) {
                $response = array(
                    'error'     => true,
                    'message'   => $e->getMessage(),
                );
            }
            catch (Exception $e) {
                $response = array(
                    'error'     => true,
                    'message'   => $this->__('Cannot add order history.')
                );
            }
            if (is_array($response)) {
                $response = Mage::helper('core')->jsonEncode($response);
                $this->getResponse()->setBody($response);
            }
        }
    }
}

有谁知道我怎么能包括前端作者的名字在后面或在哪里我需要修改我的代码。
