You may want to try this PHP form generation and validation class that does exactly what you need and more. http://phpclasses.UpperDesign.com/browse.html/package/1 It does both client and server side validation. For the client side it uses the isNaN(parseInt(value)) Javascript functions. For the server side it uses the strcmp($value,strval(intval($value))) PHP functions .
