Answer 1

It's very easy. In your array, include a param created in your extensions class.

Next code is inside Model.

array('name', 'ext.ValidateNames', 'with'=>'lastname')

Next code is from class ValidateNames into the extensions folder.

class ValidateNames extends CValidator
{
    public $with=""; /*my parameter*/

    public function validateAttribute($object, $attribute)
    {
        $temp = $this->with;  
        $lastname = $object->$temp;
        $name = $object->$attribute;
        $this->addError($object,$attribute, $usuario." hola ".$lastname);
    }
}
