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 is for, but I’m not quite sure how to use it. Here’s what I’ve got so far:

$this->addElement('password', 'password', array(
        'label'      => 'Password:',
        'required'   => true,
        'validators' => array(
            'Identical' => array(What do I put here?)
        )
    ));
$this->addElement('password', 'verifypassword', array(
        'label'      => 'Verify Password:',
        'required'   => true,
        'validators' => array(
            'Identical' => array(What do I put here?)
        )
    ));

Do I need it on both elements? What do I put in the array?

For what its worth, support for comparing two identical form fields within a model was added to the 1.10.5 release. I wrote up a short tutorial on the matter, which you can access via the below link, but the bottom line is that the Zend_Validate_Identical validator has been refactored to accept a form field name as input. For instance, to compare the values of form fields pswd and confirm_pswd, you’ll attach the validator to confirm_pswd like so:

$confirmPswd->addValidator('Identical', false, array('token' => 'pswd'));

Works like a charm.
