Create an action helper that implements functionality in preDispatch(),
and register it with the helper broker in your bootstrap. It might look
like this:
class My_CommonViewVariables extends Zend_Controller_Action_Helper_Abstract
{
public function preDispatch()
{
$view = $this->getActionController()->view;
$viewCfg = Zend_Registry::get('SITE_CFG')->dirs;
$view->assign(array(
'pubImages' => $viewCfg->images,
'jsDir' => $viewCfg->js,
'cssDir' => $viewCfg->css,
));
}
}
And then, in your bootstrap:
Zend_Controller_Action_HelperBroker::addHelper(new My_CommonViewVariables);
BTW, don't call magic methods directly; it's a bad idea. Your original
example would have been better written using "$this->view->cssDir =
$view_cfg->dirs->css;", or, if you really want to use method calls, the
assign() method (which takes either two arguments, like __set(), or an
array of key/value pairs, as in the helper I detail above).
