Sending variables to the layout in Zend Framework

Question

In my project I have a number of dynamic elements that are consistently on every page. I have put these in my layout.phtml

My question is: How can I send variables i

Answer 1

class IndexController extends Zend_Controller_Action
{

   public function init()
   {
      $this->_layout = $this->_helper->layout->getLayoutInstance();
      $this->_layout->whatever = $this->view->render('test.phtml);
   }
}

In the layout file you can call

layout()->whatever ?>

If in some actions if you don't want that section then:

public function viewAction()
{
   $this->_layout->whatever = null;
}
