Hi,
I'm submitting a phone number from an HTML form to a PHP page that examines it to see if it's an integer:
form.html:
<html>
<form method="get" action="validate.php">
<input type="text" name="phonenumber">
<input type="submit">
</form>
validate.php:
<html>
<?php
$phonenumber = trim($phonenumber);
if (is_int($phonenumber)) {
echo "Integer";} else {
echo "Not Integer";} ?> </html> However, for some reason the script doesn't recognize the number as an Integer - why is this and how can I remedy it? Jamie Saunders Mail: webprogramming@jamie-s.co.uk Web: http://jamie-s.co.uk
