JustinK101 Posted September 11, 2007 Share Posted September 11, 2007 I have a really weird problem. I know sessions are stored on the server, but this problem only happens in IE 7. Basically I have a few pages, and each page makes sure a session variable is set, if it inst, then I display an error. When I login with firefox and navigate to and from the pages everything works perfect, no error indicating that the session inst set. When I login with IE 7 and navigate it works when I go to a page back, then to another page, but when I go back to the first page I see the error that the session inst set. This makes no sense. Any ideas? I could post code but its quite involved and involves 3 pages.

JustinK101 Posted September 16, 2007 Author Share Posted September 16, 2007 Any ideas on this? It is still happening, I have degubbed for hours, I changed the name of session, nothing works. The code work perfect in mozilla, its like I.E. unsets the session which makes no sense at all. This is really pissing me off, because I have created well over 5 applications that use PHP sessions and never had a problem.

JustinK101 Posted September 16, 2007 Author Share Posted September 16, 2007 Just tested in Safari and it also works, just seems to be an IE problem.

Crew-Portal Posted September 16, 2007 Share Posted September 16, 2007 Wow multiposter.. slow down. Be patient some people have to read your post first. I get this problem all the time and its sometimes caused by IE7 not reading the includes properly and terminating them (I Think?! ) Try putting session_start(); session_auto.start(); At the top of every page! Test it out by putting in 3 or 4 pages at first so you dont waist your time realizing that it doesnt work!

JustinK101 Posted September 16, 2007 Author Share Posted September 16, 2007 You sure about session_auto.start(); That doesnt seem to be a valid function.

Jessica Posted September 16, 2007 Share Posted September 16, 2007 Do you have cookies blocked in IE7? Quote Link to comment https://forums.phpfreaks.com/topic/68797-solved-session-unsetting-itself-in-ie7-only/#findComment-349397 Share on other sites More sharing options...
JustinK101 Posted September 16, 2007 Author Share Posted September 16, 2007 No, cookies are NOT blocked, but one of my pages uses a javascript and ajax based popup window script called LightWindow, I wonder if somehow this is causing IE to loose the session. This makes no sense. Quote Link to comment https://forums.phpfreaks.com/topic/68797-solved-session-unsetting-itself-in-ie7-only/#findComment-349400 Share on other sites More sharing options...

JustinK101 Posted September 16, 2007 Author Share Posted September 16, 2007 See half the problem is, I use a lot of custom written fuctions, but none of them should be unsetting the session.

JustinK101 Posted September 16, 2007 Author Share Posted September 16, 2007 Nevermind all, I just rewrote the script to use $_GET instead of sessions, what a pain.
