#33485 [Bgs]: isset() doesn't work with a form submission

ID: 33485 User updated by: devon at 16oranges dot com Reported By: devon at 16oranges dot com Status: Bogus Bug Type: Scripting Engine problem Operating System: WinXP PHP Version: 5.0.4 New Comment: Thanx. It'd be real nice if the manual would let people know about that change. I checked through http://us2.php.net/manual/en/function.isset.php before posting here for any changes like that, but nothing was mentioned. Previous Comments: ------------------------------------------------------------------------ [2005-06-27 08:41:39] sniper@php.net In PHP 4.2.0, the 'register_globals' setting default changed to 'off'. See http://www.php.net/release_4_2_0.php for more info. We are sorry about the inconvenience, but this change was a necessary part of our efforts to make PHP scripting more secure and portable. ------------------------------------------------------------------------ [2005-06-27 07:32:10] devon at 16oranges dot com Description: ------------ Attempting to use isset() to find out when a user's submitted a form, and if they have, then I give them particular output. This works on Linux using old PHP 4.x, but I don't have access to that anymore. This doesn't work on WinXP (with SP2, if that matters). I suspect this is related to bug #29883 @ http://bugs.php.net/bug.php?id=29883 (which is supposed to be fixed), because I tested for it and it comes out with the unexpected result. I'm 110% baffled. - Devon Reproduce code: --------------- I'm using PHP 5.0.4 on WinXP (with SP2 if that matters at <form method="get" action="this_file.php"> <input type="submit" value="ad" name="adicion" id="adicion" /> </form> <?php if(isset($adicion)) { echo "expected result after form is submitted."; } else { echo "Only seen before form is submitted."; } ?> Expected result: ---------------- expected result after form is submitted. Actual result: -------------- Only seen before form is submitted. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33485&edit=1
