I don't know if this is best practice or not, but in my projects I attach
"generic" form error messages using: $form->addError("Invalid Login
Credentials.") and then manually iterate over those messages in the view:
Action Controller:
$form = new My_Form_Login();
if ($this->getRequest()->isPost())
{
if ($form->isValid($_POST))
{
$email = $form->getValue('email');
$password = $form->getValue('password');
// ...do the authentication...
$result = $auth->authenticate($authAdapter);
if ($result->isValid()) {
// success!
$auth->getStorage()->write($data);
$this->_redirect('/');
} else {
// failure: clear database row from session
$form->addError("Invalid Login Credentials.");
}
}
}
$this->view->login_form = $form;
View:
<?php echo $this->genericFormErrors($this->login_form); ?>
<?php echo $this->login_form; ?>
Helper:
class My_View_Helper_GenericFormErrors extends Zend_View_Helper_Abstract
{
public function genericFormErrors($form)
{
$xhtml = '';
if ($errors = $form->getErrorMessages())
{
$xhtml .= '<ul class="main-form-errors">';
foreach ($errors as $error)
$xhtml .= '<li>' . $error . '</li>';
$xhtml .= '</ul>';
}
return $xhtml;
}
}

A blank form isn't normal/expected. Potentially your error_reporting is
filtering the errors, or the form is not being set for the view in a certain
case. Without seeing code it is hard to say.
This may help in regards to setting error messages for the regex validators:
