I currently have the core file Session.php modified a little to keep track of login/logout information and member_ids - create_new_session() for login, destroy() for logout.

I realize that this can be better achieved with an extension using hooks - member_member_login_single after login, member_member_logout after logout.

The issue, though, is with the logout hook the system doesn't pass along any data (documentation), so there's no way for us to know the member_id of the user who just logged out.

Is there a way to accomplish this at all aside from modifying core files? I already have a hacky solution (editing core files), so I'm looking for the "right" way to do this.

Although the hook doesn't provide any information you can use, you could do a query on the exp_members table where ip_address is equal to the users ip, and sort the results by last_activity descending. Logging out should record the timestamp into the last_activity field and the ip address is updated every time a member logs in. As a result, this should then allow you to get the relevant data for that member to use in your tracking. But yes, definitely use hooks instead of hacking core files :)

  • Definitely less hacky than what I'm currently doing, as this would allow me to exclusively use an extension. I'll give it a shot and report back if it works or not. Thanks for thinking out of the box on this one! Mar 2, 2016 at 21:28
