Add a regex validator to a form element in the Zend Framework

Question

I created a Form class in zend Framework.

class Application_Form_UserSignup extends Zend_Form {

public function init()
{
    // Set the method for the display form to POST
    $this->setMethod('post');

    // Add an Firstname element
    $this->addElement('text', 'firstname', array(
                              'label'      => 'Your first name:',
                              'required'   => true,
                  'validators' => array('regex', false, array(
                'pattern'   => '/[^<>]/i',
                'messages'  =>  'Your first name cannot contain those characters : < >'))
    ));
    }

}

I would like to validate it with my own regex using the Zend_Validate_Regex validator.

There must be an error in the syntax because I get this error but I cannot figure it out.

The error is :

Message: Invalid validator passed to addValidators() Stack trace:

13 /home/damiens/workspace/manu/public/index.php(26): Zend_Application->run()
14 {main}

Any Help would be appreciated !

Its addValidatorS (multiple validators):

$this->addElement('text', 'firstname', array(
                          'label'      => 'Your first name:',
                          'required'   => true,
              'validators' => array(
                  array('regex', false, array(
                  'pattern'   => '/[^<>]/i',
                  'messages'  =>  'Your first name cannot contain those characters : < >'))
              )
));

For anyone hitting this answer from Google, the pattern would need to be /^[^<>]$/i for this to work
