Zend Framework repeated functionality

I've recently started working with Zend Framework and I've absolutely fallen in love with it and I've even decommissioned my own framework in favour of it.

But I'm missing something that is probably so painfully obvious you'll chuckle a little bit.

I have a login system and in every controller I have to put the check for the login status, I had a look at accessing the Zend Session Storage in the Bootstrap but I'm on bit of a deadline and can't afford to waste time, is there a better way to check IE in the bootstrap? instead of repeating 20+ lines of code and functionality in every controller.

Thanks in advance!

You can use a controller plugin for this. See: http://framework.zend.com/manual/en/zend.controller.plugins.html

class Your_Plugin_Login extends Zend_Controller_Plugin_Abstract
{
    public function preDispatch(Zend_Controller_Request_Abstract $request)
    {
        if (!Zend_Auth::getInstance()->hasIdentity()) {
            // send the user to the login page
            $request->setControllerName('login')
                    ->setActionName('login');
        }
    }
}

replace the controller/action names with whatever is appropriate for your login page, and 'Your' with your application's namespace.

You then register the plugin with the Front controller either in application.ini or in your bootstrap with Zend_Controller_Front::getInstance()->registerPlugin(new Your_Plugin_Login());.

Edit: If you want to put the user details in the view as well, you can do:

$layout = Zend_Layout::getMvcInstance();
$view = $layout->getView();
$view->user = Zend_Auth::getIdentity();

You can write your own controller that inherits from Zend Controller (call it e.g. DaveMac_Controller - you can define the prefix in the app's config file so that the app can autoload it (and you need to be careful with which directory you save your class in)). In this class's construct function run the check for authentication. Then change all your page's controllers to inherit from DaveMac_Controller rather than the default zend one.

If I was at home I could copy and paste some code as an example, but at work right now so hopefully the above outline is enough.

*edit Good ol' dropbox :)

application.ini

includePaths.library = APPLICATION_PATH "/../library"
autoloaderNamespaces[] = "DaveMac_"

/../library/DaveMac/Controller/Action.php

<?php 

class DaveMac_Controller_Action extends Zend_Controller_Action {


    protected $acl;
    protected $user;
    protected $userRole;

    public function init() {

        //retrieve and store user details
        $auth = Zend_Auth::getInstance(); 
        if($auth->hasIdentity()){
            $user = $auth->getIdentity();
            $this->user = $user;
            $this->view->user = $user;
            $this->userRole = $user->role;
        } else {
            $this->userRole = "guest";
        }

        //Initialise access control list
        $this->acl = new DaveMac_Acl();
    }

    protected function checkAuth($pageLevel, $redirect = "/") {
        if($this->user) {
            if(!$this->acl->isAllowed($this->userRole, $pageLevel)) {
                $this->_redirect($redirect);
            }
    } else if ($pageLevel != DaveMac_Resources::PUBLIC_ONLY_PAGE) {
        $this->_redirect('/login/returnurl/' . str_replace('/','-',$this->getRequest()->getRequestUri()));
        }
    }
}

You will probably already have your own functioms fdor checking authentication, but I thought I'd leave mine in anyway
