well, what I would do is set a variable inside my form for me to know when the form has been submitted:
<input type=hidden name='perform' value='email'>
then, when the page reloads, simply have a script that will both do the post
and use email() to email the results to yourself.
if ((isset($perform)) AND ($perform=='emai')) email_me();
I think that was what you were asking right?
