Can I validate a HTML input without using JS and HTML5?
Question
I am creating a site for legacy mobile browsers (eg: browsers running on Nokia 2760), and cannot, of course, use JS nor HTML5. Is there any way to restrict user's input to prevent them to send letters in a numeric field? Or the best I can do is to execute a server-side validation?
Thanks!
Edit: I would like to have both client and server-side validation, not only the server-side one. It is desirable for me to restrict user's input, just like an <input type="numeric" /> does. Tyiping several numbers in a old cellphone without that feature is painful.
The doctype I am using is
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML Basic 1.0//EN” “http://www.w3.org/TR/xhtml-basic/xhtml-basic10.dtd”>

Server side if your only option here.
JavaScript and the new features introduced in HTML 5 are the only client side options, and you've ruled them out.
