I am developing an eemployee management system in CodeIgniter PHP and JavaScript.

I need to find out if the client's computer is not in sleep and lock mode.

Is it possible in PHP and JavaScript or jQuery.

I am waiting for expertise Opinion and solution.

Thanks

  • Using javascript or JQuery, i would say no. And as PHP is server side language, of course not. Now you should find ways to detect if user is active on page using javascript, nothing more i guess. – A. Wolff Mar 28 '14 at 11:18

    as stated here: http://stackoverflow.com/questions/14112708/start-calling-js-function-when-pc-wakeup-from-sleep-mode you can detect a break in execution time – visualex Mar 28 '14 at 11:19
  • @visualex that's quite an interesting approach – A. Wolff Mar 28 '14 at 11:21

I think that you chose the wrong tools. You should develop a desktop application for these purposes. (.NET, Java, etc.)

Server can serve as a communication point, which receives data from the desktop application.

So no, you cannot find out if computer is sleeping from a server with PHP. This can be done IF the computer sends it's state to the server through the desktop application.

Not really and every solution with an open browser window and an interval can be tricked. Best way is a native windows app/os x app.

In PHP - no. PHP is server side, you cannot reach any informations about client unless client send it to you.

In JavaScript, I don't think so, and even if (like here), it's on client side and can be tricked.

I suggest you to solve this problem with desktop version of your application, or at least some background proccess, which will monitor this informations.
