Zend Framework: Set a validator for starting letter as Capital

Question

For my school project, I try to make a form in Zend.

I would like to insert a Validator that the first letter has to be a Capital letter.

What should I change in this piece of code to make this work?

        $voornaam = $this->createElement('text', 'voornaam');
    $voornaam->setLabel('Voornaam:')
            ->setAttrib('size', 50)->addValidator('StringLength', false,array(2,30))
                ->setRequired(true);

If anyone could help me with this, thanks in advance!

Maybe this custom validator will be helpful:

class My_Validate_FirstCapital extends Zend_Validate_Abstract {

    const CAPITAL = 'capital';

    protected $_messageTemplates = array(
        self::CAPITAL => "First letter is not capital"
    );

    public function isValid($value, $context = null) {            

        if ($value != ucfirst($value)) {
            $this->_error(self::CAPITAL);
            return false;
        }

        return true;
    }    
}

I didn't test it, but is should work.

Another way would be to use Zend_Validate_Regex, e.g.

//match first capital letter
$validator = new Zend_Validate_Regex(array('pattern' => '/^[A-Z]/'));
// and add it to your element, ->addValidator($validator)
