En un view helper accedes a la vista con $this->view
Código PHP:
class Mi_Helper_Idioma extends Zend_View_Helper_Abstract{
public function idioma(){
$request = Zend_Controller_Front::getInstance();
$modulo = $request->getRequest()->getModuleName();
$controller=$request->getRequest()->getControllerName();
$action=$request->getRequest()->getActionName();
echo"<a href=".$this->view->url(array('module' => $modulo, 'controller' => $controller, 'action' => $action)).">Idioma</a>";
}
}
Saludos!
