You could use javascript to restrict the data. If you use jquery than have a look at:
http://docs.jquery.com/Plugins/Validation

However, you should also do a server side validation. You could use preg_match to check if the data conforms:
http://php.net/manual/en/function.preg-match.php

preg_match('#[a-zA-Z]#', $input);
