如果管理员已登录,请检查前端

我编写了一个模块,它的行为应该与内联翻译相同:

如果我是管理员而且我已登录,我可以在前端看到一些特别的内容.但如果我不是管理员,那么我什么也看不见.

如何让模块知道在前端区管理员登录？

更新1

为了澄清一些我想描述的模块行为:

后端 - 只需保存配置一个值的表单.

前端 - 观察者,正在与一个事件挂钩.在Observer的功能中,我需要检查是否

当前前端用户登录到adminpanel,换句话说用户观看前端是admin.

因为通过此检查,我想向管理员用户提供一些基于前端更改的功能.

问题是我在前端有以下会话($ _ SESSION)转储:

    )

也许没有办法从前端访问管理员用户.好吧,我尝试通过Cookies.

我需要在控制器中执行此操作,特别是preDispatch()方法,我认为这是一个明智的用例.

// Ensure we're in the admin session namespace for checking the admin user..
Mage::getSingleton('core/session', array('name' => 'adminhtml'))->start();

$admin_logged_in = Mage::getSingleton('admin/session', array('name' => 'adminhtml'))->isLoggedIn();

// ..get back to the original.
Mage::getSingleton('core/session', array('name' => $this->_sessionNamespace))->start();
