Is it possible to count online time

Is it possible to count user's online time? I remember that I asked such question but I did not get any results by searching this forum..

@sharonyue I am still wondering how to make a record of user's online time.

I added two new hooks to make this easier.

You can use these hooks in a plugin to detect when a user connects and disconnects and increase their online time. Here is some sample code.

myPlugn.actionSocketsConnect = async function (hookData) {
      if (hookData.socket.uid > 0) {
         await user.setUserField(hookData.socket.uid, 'startTime', Date.now());
     }
};

myPlugn.actionSocketsDisconnect = async function (hookData) {
     if (hookData.socket.uid > 0) {
         let startTime = await user.getUserField(hookData.socket.uid, 'startTime');
         startTime = parseInt(startTime, 10) || Date.now();
         const newValue = await user.incrementUserFieldBy(hookData.socket.uid, 'onlinetime', Date.now() - startTime);
         await db.sortedSetAdd('users:onlinetime', newValue, hookData.socket.uid);
     }
};

This is increment the users online time when they disconnect and also create a sorted set to quickly get the users sorted by their online time value.

@baris Thank, it looks great. BTW, is it possible to show online time just as user's post number without any plugin?

Since this adds a new custom field you need to display it in your custom theme/plugin or modify persona to display it where you want.
