How to share an object (e.g. instance of Zend_Auth) between multiple controllers

Question

I have my application within Zend Framework 1. I'm using Zend_Auth to manage sessions. Below is how I check authentication within the IndexController class:

class IndexController extends Zend_Controller_Action
{

    public function init()
    {
      $auth = Zend_Auth::getInstance();

      if ($auth->hasIdentity()) {
        $this->view->user = $auth->getIdentity();
      }
    }

    public function indexAction()
    {

    }

}

Basically it just sets a view variable of user to whatever is in the auth object. Within my view I can check if the user variable is set and act appropriately (eg Display "Welcome Tom!" and a logout link)

However, this functionality is not available yet in my other controllers. Rather than duplicate the same code within each init() method, how can I do this? I'm not so sure where to put the code for this.

UPDATE:

I tried to do something like this in the bootstrap file:

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
  protected function _initView() {
    $auth = Zend_Auth::getInstance();

    if ($auth->hasIdentity()) {
      $this->view->user = $auth->getIdentity();
    }
  }
}

..but I get the following error: Notice: Indirect modification of overloaded property Bootstrap::$view has no effect in /var/www/budgetz/application/Bootstrap.php on line 9 Warning: Creating default object from empty value in /var/www/budgetz/application/Bootstrap.php on line 9 .

Answer 1

You can use an abstract class inheriting from Zend_Controller_Action like this:

abstract Class Yourlibrary_Controller_ControllerAbstract extends Zend_Controller_Action
{

    public function preDispatch()
    {
        $auth = Zend_Auth::getInstance();

        if ($auth->hasIdentity()) {
            $this->view->user = $auth->getIdentity();
        }
    }
}

And yours Controllers inherit Yourlibrary_Controller_ControllerAbstract not Zend_Controller_Action
