Login Logout status maintenance

[samatair]

I am using sessions to maintain login/logout status. I update the table when a user logs in and logs out. But some users don't logout. How to automatically log them out and update the status.
I had used the meta tag to refresh the page after 20 mins, so if the page is kept opened it automatically logs out the user after 20 mins. But it's not providing me results which I expect. Please anyone let me know, how to do this?

Thanks for your help!

You will have to store the time and date of the last login, and then compare it to the current time and date, and if it's over saying 30mins, assume the user has logged out. There's no exact way of knowing, unfortunately.

Yes, I have stored the Last Login date and time. So should I use a Cron or a Schedule Job to run a code with every 30 mins to check and update the user status?

No, I don't think that's necessary.

You must have a page that checks if the user is logged on, maybe the user profile, to show if he/she is logged on?

You could do the update on that page.

I think your solution might work. But I have to check it. Thank you very much Markus
