Password confirmation using Zend Form and Validators

A while back i needed a password confirmation field for my users. I looked and found this neat little snippet. I cant remember who created it originally so i cant give credits to the person but its quite easy to use. Just add this to your library and create a new validator object like this.

This would be in your form where you want to have password confirmation.

    It would be more general purpose if you could configure the validator with the names of the two password fields. Maybe passed in the constructor?

    Thanks for a great snippet. ;-)

    Im getting the Not match always, even if I put same passwords in both of the textbox..


    const NOT_MATCH = ‘notMatch’;

    protected $_messageTemplates = array(self::NOT_MATCH => 'Passwords do

    not match.’);

    public function isValid($value, $context = null)
    $value = (string) $value;

    if (is_array($context)) {
    if (isset($context['confirmation']) && ($value ==$context['confirmation'])) {
    return true;
    } elseif (is_string($context) && ($value == $context)) {
    return true;

    return false;

    And my Form
    $password = new ZendFormElement_Password(‘passwd’,array(
    ‘required’ => true,
    ‘label’ => ‘Password’,
    ‘size’ => 11

    $confirmation = new Zend_Form_Element_Password('confirmation',array(
    'required' => true,
    'label' => 'Re-Password',
    'size' => 11
    //$confirmation->addValidator('PasswordConfirmation',array('passwd'), true);

    Could you help me please…

    the validator doesnt take any arguments. Just parse the validator to your elements

    // more form code here...
    // $password = new ZendFormElementPassword(.....);
    // $confirm = new Zend

    $confirmValidator = new MyValidatePasswordConfirmation();

    Nice way, but there is an already existing validator called ZendValidateIdentical

    ZendValidateIdentical supports also the comparison of form elements. This can be done by using the element’s name as token. See the following example:

    $form->addElement('password', 'elementOne');
    $form->addElement('password', 'elementTwo', array(
    'validators' => array(
    array('identical', false, array('token' => 'elementOne'))
