single connection per user on platform

Question posted by: theoni (Newbie) on July 9th, 2008 07:04 AM
Hello all!

I am working on a platform and there is a restricted area when users need to login. The issue is that multiple users can login with the same username/password at the same time which I don't like. I want when a user logs in no other person to be able to log in the system with the same username/password. Is there a way I can implement that on the server? I have tried to implement the operation with php but it does not work right. I would highly appreciate any help.

Thank you
Theoni

yes, there is no way to catch the user closing the browser. I have tried with javascript but it didn't work.

You have several options that you can use to indicate that a user is logged it. Create a table for logged in users, or just add a logged in flag to your users table.

You tried firing an AJAX request when the page is closed?

Then you need to post the relevant parts of your code and explain where it fails.

P.S I'll now move this to the Javascript/AJAX forum.

time the user out after 5 mins, allow cookies to maintain state, and prevent double login on the server using a persistent object, or even a csv file of active users or something.
