How to verify password field in zend form?

Question

In my form, I\'m trying to verify that the user fills in the same value both times (to make sure they didn\'t make a mistake). I think that\'s what Zend_Validate_Identical

Answer 1

$token = Zend_Controller_Front::getInstance()->getRequest()->getPost('password');
$confirmPassword->addValidator(new Zend_Validate_Identical(trim($token)))
                  ->addFilter(new Zend_Filter_StringTrim())
                  ->isRequired();   

Use the above code inside the class which extends zend_form.
