Hey Chris,
1) Use sessions (read up on it if you don't know it; in short:
session_start() at the very beginning of your script creates a $_SESSION
array that is persistent through subsequent page calls)
2) Submit the form to the search page and preprocess it by putting the
post vars into the session, then use header() to relocate to the actual
processor
3) Have the actual processor work, i.e. the result list page script,
with the session data. Do not destroy the session data afterwards.
Now if a user uses the back-button from your result list, he will again
reach the search page, without the 'wanna send form again' message box.
I very strongly advise you not to break the browsers back button
functionality. It's there for a reason and people rely on it to behave
accordingly. Don't duplicate functionality that the browser already has.
HTH,
Stijn

Hi guys,
this might be a noob- question, but I simply do not care anymore.
After a few hours of fiddling with this @/**&%$ (screaming
"AAaaaaahhhh"), I would like to ask you.
So what I have is this: I have a search engine for a car market, which
has about 30 $_POST- vars. Now when the user clicks on a result link,
it takes him to the car details page. Now when he hits the back
button, he either gets the "Page has expired" (IE) or the "Wanna send
the form data again" message box (FF).
Now I would like to have kind of a "back-button", so the user will see
the reusult list again without having to deal with this.
I guess what I'm asking for is a one-click re-submission of POST
data... Do you have a clue on how to do this?
Cheers for any answers!
Chris
