flappy_warbucks Posted September 6, 2011 Share Posted September 6, 2011 Phone them up and ask them? Seriously: log the IP address, and time they last clicked a link. (to save DB space, prob best as a flat file system unless you got a large database capacity). Then you can write a script to show when they last clicked a link. with a time limit of 5 minutes per click, that should be a reasonable indication of when they're online, and what page they're on.

Psycho Posted September 6, 2011 Share Posted September 6, 2011 You can't "check" their status. You can update the last time they accessed your site. Just add a function that will run on every page load to update a "last_access" timestamp for users whenever they load a page. Then, determine who is "online" based upon that timestamp, by choosing an appropriate time period: e.g. any users who's "last_access" time is within the last 10 minutes (or whatever period you want to use). log the IP address, and time they last clicked a link. (to save DB space, prob best as a flat file system unless you got a large database capacity). A flat file, seriously? How does a flat file save space over a database? Plus, since this will be updated every time a users access a page and when you need to get the data there is a huge possibility for file corruption.

Pikachu2000 Posted September 6, 2011 Share Posted September 6, 2011 http is a stateless, connectionless protocol, so it doesn't matter if the browser has your site loaded and just sits there. Quote Link to comment Share on other sites More sharing options...

I understand perfectly what you want to do, and I also understand perfectly the reasons it doesn't work like that. Aside from setting up some elaborate, resource-wasting system using keepalive messages with JS/AJAX, the best you can do is log the time of the last activity of the user, and if it's been more than a predetermined amount of time since they last did anything, consider them inactive/unreachable/deceased/drowned/whatever. Just like mjdamato and flappy_warbucks said. Quote Link to comment Share on other sites More sharing options...
WebStyles Posted September 6, 2011 Share Posted September 6, 2011 consider them inactive/unreachable/deceased/drowned/whatever. apparently sleeping is the order of the day... who are all these people suddenly sleeping in front of the computer?

Psycho Posted September 6, 2011 Share Posted September 6, 2011 but what if the user is sleeping and he is online (means the website is open for an hour or two).... you are not getting me guyzz... As others have stated, youzz are the one not getting it. If you followed the advice given and a user left their browser open to your site (with no activity) for two hours then they would not be seen as "online" since it would have been more than 15 minutes (or whatever period you set) since their last activity.
