Dan, I'll give you a little piece of advise that was given to me a little while back on this list:
Go to http://www.killersoft.com/ and grab a copy of the validateEmailFormat program. <QUOTE> PHP4 translation of Jeffrey E.F. Friedl's definitive Email Regex Program from O'Reilly's Mastering Regular Expressions. This function is used to confirm if an e-mail address adheres to the RFC 822 specification for internet email addresses. </QUOTE> Rather than trying re-invent the wheel, why not use something that conforms closely to specs, and is widely accepted by many development groups. All you'll have to do is something like (function names and filenames may not be right): <? include('inc/validEmailFormat.inc'); if(!validEmailFormat($emp_email)) { echo "<center>please enter a valid email address</center>"; } ?> Side topic: of course, you aren't checking for a valid email address at all, your checking to see if the email address LOOKS valid. You're not checking to see if the address is attached to an email box, or furthermore if there's anyone at the other end to open/read your email... you're just validating the appearance of the address to fall within RFC 822 specs. Subsequently [EMAIL PROTECTED] and [EMAIL PROTECTED] will both return valid. The only way to ensure an email address is truely valid is to send an email to it, and have them respond... indicating that the address is linked to an email box and furthermore, someone opened the email, read it, and responded. Even then, this could be done by a robot I guess.
