Hi,
Here's one function to check an email address:
http://www.ilovejackdaniels.com/php/email-address-validation/
For phone, you could do:
if (!preg_match('/^[2-9]\d{2}-\d{4}$/', $email)) {
// Bad phone
}
For address, you could do:
$addr = preg_replace('#[^[[:print:]]]|[/\\\\]#', '', $addr);
You can check that each item is filled-in like so:
$errors = array();
if (trim($_POST['name']) == '') {
$errors[] = 'Name is missing.';
}
if (trim($_POST['addr']) == '') {
$errors[] = 'Address is missing.';
}
foreach ($errors as $err) {
echo "<span style=\"color: red;\">$err</span><br>";
}
