Form Validation: return calues for rules?

[eluser]mindph[/eluser]
Hi

Is it possible somehow, to have the form validator return which rule was failing validation?

The purpose why I could need this is simply: I dont want to display only the errors, but also hilight the field what failed validation.
So that I could get something like

Code:

if($this->form_validation->rule('firstName') == FALSE){
$formData['firstName'] = array('style' => 'background-color: red');
}

I am not sure if you get what I mean... oO
