Hi guys, I am back with another login twister. Earlier i tried to create a yahoo like login system which ensured that a given user was logged in only on one machine even if that user tried to do a multiple login from same or different machines. So after a great deal of effort and with a lot of support from the forum i decided it would be best to not allow a second , the new login, at all if the user was logged in. So the new login fails saying that the user is already logged in. I am now using a sliding jquery login panel that i picked up from the net and i tried and implement this new logic and guess what ? I ran into another issue. So the panel works fine. I'll put the login procedure in steps; 1. I input the username and password and I login. The initial screen provides the username and password and a login button. Also a registration form for a new login registration. The display shows Guest for user. 2. The user logs in & is greeted by his 'username' that it picks from a database. When the panel is expanded it now opens to a new page ( say PAGE 1) which has two hyperlinks: a) to play a movie and b) to logout. 3. Both work fine. So far so good. 4. Now I run the login page again in a new tab and because an instance of it is already running, it opens on PAGE 1 which has the two hyperlinks a) movie and b) to logout. Since the panel is running sessions and since i am running the two on the two tabs of a browser, the sessions would ensure that the session values are the same for the instances in both tabs. 5. Now I logout from the 2nd (newer) tab. ( actually since there are two instances running on the two tabs of the same browser I can logout of either.) The sessions is destroyed and the logout page is displayed. Since the sessions are destroyed, they must be destroyed from both instances. At this point of time the first instance / tab is still showing the PAGE1 as it should but it is now a dead session. However now when i press the a) option, the hyperlink to a movie, it plays !!!!! WHY should the movie play when the session is destroyed. 6. So in effect, while i am effectively logged out because of a logout command in one of the two tabs of the browser, the hyperlink to the movie in the other tab is still active. which is a great flaw i think. I mean it should not behave like that. So does anyone have any idea why this is happening and how it may be over come?? A bit of code showing that which makes the PAGE 1 <div class="left"> <h1>Members panel</h1> <p>You can put member-only data here</p> <a href="registered.php">View a special member page</a> <p>- or -</p> <a href="?logoff">Log off</a> </div> registered.php actually runs a movie - the a) option - or the user can logoff - the b) option Please HELP, stuck on this one again.
