track unique login

[Anon]

Hi,

How can I only allow user to login once per session?

Let say once he login, his account login will be locked. This can simply done by adding a field in MySQL eg. LOGIN_ONCE=Y/N. But what if the user accidently close the browser, so it might create a deadlock here.

Any better solution for this?

Thanks

But if they close the browser accidentally, their session is destroyed. So... have a field in the database storing their current session_id. If the session_id they're using doesn't match the one stored, then this is a different session.

Hi Grumbler,

Can you give me rough idea how can i track the unique user login, via controlling by session_id??

Thanks
