How to pre-send in the Zend Framework?

I want to use _forward()in preDispatchafter checking the user login to each controller.

The scenario is quite simple: if the user is not logged in, he must be redirected to loginActioneither the same controller or another controller.

This will cause an endless loop, since the sending process will start again, the call again preDispatch, and the forwarding will start all over again.

The only solution I could come up with is to check if loginActionthe request is set.

So my question is: how does a complex developer handle this problem?

UPDATE Only after pressing the "Send" button did the ghost of holy awareness appear;) Another idea would be to create LoginControlleran input request for processing. Or is there an even better way?

I use a combination of Zend_Controller_Plugin and AuthController to protect my sites. It supports password reset, forced password changes and automatic account lockout, hence the moderate complexity.

, Doctrine, , , , . , , foo.

Plugin

<?php
class Hobo_Controller_Plugin_Auth extends Zend_Controller_Plugin_Abstract
{
    public function preDispatch(Zend_Controller_Request_Abstract $request)
    {
        $auth = Zend_Auth::getInstance();
        if ($auth->hasIdentity()) {
            if ('logout' != $request->getActionName()) {
                if (! $request->getParam('force_password_change')
                    && $this->_checkPasswordExpiry($auth->getIdentity()->username)
                ) {
                    $request->setParam('force_password_change', true);
                    $request->setModuleName('default')
                        ->setControllerName('auth')
                        ->setActionName('change-password');
                }
            }
        } else {
            // Defer more complex authentication logic to AuthController
            if ('auth' != $this->getRequest()->getControllerName()) {
                $redirector = Zend_Controller_Action_HelperBroker::getStaticHelper('redirector');
                $redirector->gotoSimple('restricted', 'auth');
            }
        }
    }

    protected function _checkPasswordExpiry($username)
    {
        // Look up user and return true if password is expired
    }
}

AuthController

<?php

        $this->_noticeMessenger->setActionController($this)->init();
        $this->_noticeMessenger->setNamespace('notice');

        $this->view->errors = $this->_errorMessenger->getMessages();
        $this->view->notices = $this->_noticeMessenger->getMessages();

    public function preDispatch()

                    'logout', 'identify', 'forgot-password', 'reset-password', 'restricted'))
                ) {

Edit: perhaps too tired to understand the real problem. I would start with something like a secure / private member in every entry-protected controller, for example protected $authNeeded = true;, and check it in Zend_Controller_Action::init(). This can lead to re-code, so another option is to simply execute this code in AuthNeededController, which extends all registration-controlled controllers.
