[jQuery] Validation plugin remote problem

[jQuery] Validation plugin remote problem


I'm using CakePHP, jQuery and the validation plugin. I'm having some
problems. I'm trying to check if a email is already in use but I can't
seem to get it too work.
I'm just trying to get a error message to see that it works but I
can't seem to get it right.
Javascript:
$(document).ready(function() {
    $("#UserIndexForm").validate({
        rules: {
            "data[User][email]": {
                required: true,
                email: true,
                remote: "/"
            },
            "data[User][passwrd]": {
                required: true,
                minlength: 5
            },
        },
        messages: {
            "data[User][email]": {
                required: "Du måste ange en e-post adress.",
                email: "Du måste ange en giltig e-post adress.",
                remote: "E-post adressen du angav är upptagen."
            },
            "data[User][passwrd]": {
                required: "Du måste ange ett lösenord.",
                minlength: "Ditt lösenord måste vara minst 5 tecken."
            }
        }
    });
});
And the controller:
        if ($this->RequestHandler->isAjax() && !empty($_REQUEST['data']
['User']['email'])) {
            $valid = 'false';
            echo $valid;
        }
Thanks!
