[PHP] $_POST- Vars - Back-Button
Hi guys, this might be a noob- question, but I simply do not care anymore. After a few hours of fiddling with this @/**%$ (screaming AAa), I would like to ask you.

Re: [PHP] $_POST- Vars - Back-Button
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 Christian Hänsel schreef: Hi guys, this might be a noob- question, but I simply do not care anymore.

Do you have a clue on how to do this? The resubmit page is being displayed because the results page is the result of a form POST. You can do one of two things: 1. Change your search form to a GET request. 2. Stuff the existing POST data into the session and have your results page use that before looking to the POST data. -- Richard Heyes +44 (0)844 801 1072 http://www.websupportsolutions.co.uk Knowledge Base and HelpDesk software that can cut the cost of online support -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
