Hi,
A few pointers:
1) Use the buildfunction mail().
See www.php.net for details.
2) When you use one script to do everything, you are only making your life
unneeded difficult. You code will end up with a spaghettilike logictree to
handle each situation. A situation you should avoid.
Consider changing your action-tag in the form into another script, like
logout_and_email.php where you handle the logic.
You script shows that you already know how to retrieve information from a
POST. I suggest you take the logic for emailing to a new script.
3) How to end a session?
This can be done in many ways.
Here is one that empties the session, but keeps the session (id) around for
future use:
$_SESSION = array();
or
session_destroy()
Read it all here:
