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!

I'm afraid there is not such validator by default. You will have to create your own validator class and add this to your form element. — Fidi, Jul 13 '11 at 14:34

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)

I tried the first answer, because It would be the best solution. I put it before my Class where it should be used. When filling my form and hitting submit, I don't get any error's. What should I do more to make it work? Zend_Validate_Regex solutions works like a charm – JorritK Jul 13 '11 at 15:19
@JorritK. you create new validator `$v = new My_Validate_FirstCapital();` and then add it to your element (like for Zend_Validate_Regex). – Marcin Jul 13 '11 at 15:27
Works absolutely great, I can not vote up yet, but as soon as I can I will. Thanks a lot! :D – JorritK Jul 13 '11 at 15:36
@JorritK. Glad I could help. You can accept the answer. This will also give you some points. – Marcin Jul 13 '11 at 15:38

You can always use the regex validiator for things like this. I am little busy so please feel free to step in and provide a complete code example.

Oh, somebody just did
