Look at the standard HTTP Header from a PHP session: HTTP/1.1 200 OK Date: Wed, 03 Dec 2003 03:02:04 GMT Server: Apache/1.3.27 X-Powered-By: PHP/4.3.2 Set-Cookie: PHPSESSID=9698e85f93d57ec844194ae7943552c8; path=/ Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Connection: close Content-Type: text/html Specifically the cache-control. PHP has these settings by default so you can NEVER rely on the browser to "remember" form data because if it adheres to the HTTP Headers (which it ideally should), it's going to blank it all. Here's an option for you that I use: 1) On your page with the form, submit the data via a transfer (XT) script. This script places all of the form values into session variables and then redirects to Page 2. 2) On the next page display whatever you need. If they click BACK in their browser, it's going to return to the first page, not your XT file. This page should, at the start of it, check for the existence of the session variables. If they exist and the data is safe, populate the form with it. Basically using this method you can "save" the form contents for however long you want the session to exist and when they go back to that page (either by typing the URL in directly or using the Back button in their browser) the data will be ready for you to populate the form with. If you want some example code just shout. -- Best regards, Richard mailto:[EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
