I can't understand why the code doesn't seems to function very well
can you help me please because I can't understand why the code doesn't seems
to function very well:
in onkeypress it must verify if insert number or string value in the fiels,
but it doesn't seems to function very well
(in frontpage it works but here it doesn't)
PROGRAMMA IN FRONTPAGE
<form method="get" name="f">

numeralsOnly(event)"/><br/>
stringa <input type="text" name="t2" onkeypress="return
lettersOnly(event)"/><br/>

Javascript is *client*-side while PHP is *server*-side.
Assuming that PROGRAMMA IN FRONTPAGE and PROGRAMMA IN PHP are seperate
files, your PHP program will not be aware of any data until the form is
submitted to the server, therefore your validation needs to be done in
the browser.

Andy
