can't figure out how to validate zend_form - zend-framework

Question

I'm trying to figure out how to get this zend form to validate. I don't understand:
Are the addValidator() arguments specific validators? Is there a list somewhere of those validators?
I've got this in the forms/contact.php:
class Application_Form_Contact extends Zend_Form
{
public function init()
{
$this->setAction('index/process');
$this->setMethod('post');
$name = new Zend_Form_Element_Text('name');
$name->setLabel('Name:');
// $name->addValidator('alnum');
$name->setRequired(true);
$email = new Zend_Form_Element_Text('email');
$email->setLabel('Email:')->setRequired(true);
$confirm = new Zend_Form_Element_Text('confirm');
$confirm->setLabel('Confirm Email:')->setRequired(true);
$phone = new Zend_Form_Element_Text('phone');
$phone->setLabel('Phone:')->setRequired(true);
$subject = new Zend_Form_Element_Select('subject');
$subject->setLabel('Subject:')->setRequired(true);
$subject->setMultiOptions(array('Performance'=>'Performance',
'Workshop'=>'Workshop',
'Other'=>'Other'
));
$message = new Zend_Form_Element_Textarea('message');
$message->setLabel('Message:')->setRequired(true);
$message->setAttrib('rows','6');
$message->setAttrib('cols','30');
$submit = new Zend_Form_Element_Submit('Submit');
$this->addElements(array( $name,
$email,
$confirm,
$phone,
$subject,
$message,
$submit
));
$this->setElementDecorators(array
('ViewHelper',
array(array('data' => 'HtmlTag'), array('tag' => 'td')),
array('Label' , array('tag' => 'td')),
array(array('row' => 'HtmlTag') , array('tag' => 'tr'))
));
$submit->setDecorators(array('ViewHelper',
array(array('data' => 'HtmlTag'), array('tag' => 'td')),
array(array('emptyrow' => 'HtmlTag'), array('tag' => 'td', 'placement' => 'PREPEND')),
array(array('row' => 'HtmlTag') , array('tag' => 'tr'))
));
$this->setDecorators(array(
'FormElements',
array('HtmlTag' , array('tag' => 'table' , 'class' => 'formTable')),
'Form'
)
);
}
}
my controller is:
public function indexAction()
{
$this->view->form = new Application_Form_Contact();
}
public function processAction()
{
// $this->view->form = new Application_Form_Contact();
//
if ($this->_request->isPost()) {
$formData = $this->_request->getPost();
// echo 'success';
$this->view->data = $formdata;
} else {
// $form->populate($formData);
}
}
I'm a newbie, so I'm probably making some obvious errors that I don't see. I'm trying to do basic validation:
all fields must be filled out
all html gets stripped
email and confirm
email fields must match
email must be valid format.
Any help would be greatly appreciated!

Have you tried isValid() ?:
$form = new forms_ContactForm();
if ($this->_request->isPost()) {
$formData = $this->_request->getPost();
if ($form->isValid($formData)) {
echo 'success';
exit;
} else {
$form->populate($formData);
}
}
$this->view->form = $form;

About the validators:
$firstName = new Zend_Form_Element_Text('firstName');
$firstName->setLabel('First name')
->setRequired(true)
->addValidator('NotEmpty');
$lastName = new Zend_Form_Element_Text('lastName');
$lastName->setLabel('Last name')
->setRequired(true)
->addValidator('NotEmpty');
$email = new Zend_Form_Element_Text('email');
$email->setLabel('Email address')
->addFilter('StringToLower')
->setRequired(true)
->addValidator('NotEmpty', true)
->addValidator('EmailAddress');
Heres the link to the Zend documentation about Zend fiorms and validators.
