Back button not working after PHP submission?

If you go to www.classiccarsforsale.co.uk and enter "ferrari" for example in
the search box, you get a list of cars generated by PHP/MySQL.

If you then click on a car you see its advert

If you then click the "back" button in IE you get a "Warning, this page has
expired" message.

Other sites seem to display the last page generated rather than this
message.

How do I do this?

Many thanks

Sorry for the late response but I think I know this one :-). LOL. I've
encountered this myself. You need to use GET instead of POST to send data.

I always capture the values into a session and when the form is created
I echo the session values into the value="" section, or whatever is
needed, different in the case of checkboxes etc., have to mark as
selected="selected" etc.

You could use normal cookies too if you don't want to start a server
session.

I usually use a header redirect back to forms when data is invalid or
when a succesful submission is made, I use a session var 'messages' to
hold any messages to print at the top of the form

eg.

$_SESSION['messages'] = 'Your submission was invalid';
exit(header("Location: {$_SERVER['PHP_SELF'}"));
