检查前端是否已登录管理员 [英] Check on frontend if admin is logged in

问题描述

我编写了一个模块，该模块的行为应与内联翻译相同:

I write a module, which should behave in them same manner as inline translation:

如果我是管理员并且已经登录，则可以在前端看到一些特殊信息.但是，如果我不是管理员，那么我什么也看不到.

If I am admin and I am logged in, I can see something special on frontend. But if I am not admin, then I can't see anything.

如何让模块知道前端区域的管理员已登录?

How to let module know that on frontend area admin is logged in?

更新1

为了澄清一些事情，我想描述一下我的模块行为:

To clarify things I want to describe a little bit my modules behaviour:

后端-仅保存为配置一个值的表单.

Backend - form which simply saves to config one value.

前端-观察者，它挂接到事件.在Observer的功能中，我需要检查

Frontend - Observer, which is hooking to an event. In Observer's function I need to check if

当前前端用户已登录adminpanel ，换句话说，正在监视前端的用户是admin .

由于此检查，我想向管理员用户提供一些基于前端更改的功能.

Because with this check I want to provide to admin user some functionality based on frontend changing.

问题是我在前端进行了以下session($ _ SESSION)转储:

The thing is that I have following session($_SESSION) dump on frontend:

        [session_hosts] => Array
            (
                [...] => 1
            )

    )

也许无法从前端访问管理员用户.好吧，我尝试通过Cookies.

Perhaps there is no way to access admin users from frontend. Well I try via Cookies.

推荐答案

我需要在控制器中做到这一点，特别是preDispatch()方法，我认为这是一个明智的用例.

I needed to do this in a controller, specifically the preDispatch() method, which I think is a sensible use case.

// 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();
