Set a flag
either cookie, or db based.
in your submit code, set the flag, fairly simple
if ($submitted) {
//error i've been posted already
}
else {
//do form submit stuff.
$submitted=1;
//SetCookie or session variable...
}

Subject: [PHP] Avoiding repost
I have a card system that will ask for the required information, and
one hits a 'Send' button to send the card. This will submit all the
information to a database and send the viewer to a 'Thank You' page.
The problem is, if they hit reload on that (Thank You) page, (and answer
'yes' to the 'Repost Data' question), a second card will get submitted -
with the same information as the first. Needless to say, someone can
sit at that screen, and hit 'reload' several times and send the same
card over and over again, flooding the recipient's mailbox.
How can I avoid this?
