single connection per user on platform

[theoni]

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

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?

yes that is how i tried to implement it.

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.
