Beauford Posted October 20, 2008 Share Posted October 20, 2008 I want to stop users from logging in twice. I have set up a table with the user id and timstamp and it works fine, where I am confused is how I check it. First, does the time need to be updated on every page, and in the crontab what am I looking for? For example, if I set the crontab for for 5 minutes and check the time against it, the user could just wait 6 and login again - defeating the purpose. Am I making any sense, or just missing something simple here? I guess I could set it to log the user out after the 5 minutes if there is no activity, then they could log in again. Any suggestion are appreciated. Link to comment https://forums.phpfreaks.com/topic/129328-stop-users-logging-in-twice/ Share on other sites More sharing options...
.josh Posted October 20, 2008 Share Posted October 20, 2008 log in with the same account, or log in under multiple accounts? Link to comment https://forums.phpfreaks.com/topic/129328-stop-users-logging-in-twice/#findComment-670461 Share on other sites More sharing options...
ratcateme Posted October 20, 2008 Share Posted October 20, 2008 so you want the same user not to be able to login twice at the same time? what i would say is but a timestamp in the database when the user loads a new page update the timestamp. every time the user logs in check the timestamp. if 5 mins has gone past since last recorded time then assume the user has left your site and come back. if it is less than 5 mins then there might be two people with the same password. this could annoy people though if browsing the browser accidentally crashes they have to wait 5 mins to use your site.

discomatt Posted October 21, 2008 Share Posted October 21, 2008 The easiest way is a custom session handler... Ideally one that implements a database engine.

Beauford Posted November 2, 2008 Author Share Posted November 2, 2008 Figured it out. I stored the session ID in the DB and if they close their browser and not log out and try to log in again, the sessions won't match. I put a notice up advising them of this and logging in again would log out anyone else.
