[fw-general] Zend Form Validators and their options

[J DeBord]

In the code below I have added the EmailAddress validator. In the case of
this validator and the others, where can I find out what options I am able
to pass to them?

For example 'validators' => array(array('EmailAddress', false, array('WHAT
OPTIONS CAN I PUT HERE?))),

$this->addElement('text', 'email', array(
                'decorators' => $this->_defaultDecorators,
                'label' => 'Email Address',
                'required' => true,
                'validators' => array(array('EmailAddress', false,
array())),
                'filters' => array('StringToLower'),
                'class' => 'text'
        ));

In this case I am interested in setting the invalid message for the
emailaddress validator, but I think I can figure that out myself once I know
how to determine exactly what options are available to be passed in the
example above.

So generally speaking about validators added in this context, how do I know
what options are available to be set?

Thanks a lot.
