The fourth parameter to _forward() is an array of paramater values to
set in the request object:
$this->_forward('index', 'index', null, array('error' => 'Bad login
credentials'));
You'd then retrieve this in the other controller using _getParam():
$error = $this->_getParam('error', false);
if ($error) {
// assign error to view?
}
Alternatively, you could simply set a view variable, and check for that
in the home page view script:
$this->view->error = 'Bad login credentials';
Finally, you could use the FlashMessenger helper (as Darby has already
noted); this helper is best used for passing messages to subsequent
requests.
