PHP Code:
$subject = "Form Submission"; // Subject of email sent to you.
$emailadd = "chris_elizabeth@xtra.co.nz"; // Your email address. This is where the form information will be sent.
$url = "www.oceansidegraphics.co.nz/thankyou.htm"; // Where to redirect after form is processed.
$req = "0"; // Makes all fields required. If set to '1' no field can not be empty. If set to '0' any or all fields can be empty.
