How to track the total number of logged in members
Posted: Fri Jun 24, 2005 5:41 am
I am currently working on a membership based web site. I need to display the number of members logged in that system. To do this I have set a flag in the database which is set to 1 whenever a user is logged in the system and when the user clicks on the ‘Log Out’ link a query is fired that sets the same flag to 0. To display the total number of logged in members I run a query that counts the number of records whose flag is set to 1.
However this method has a major shortcoming. When users do not click the ‘Log Out’ link but just close the browser. In such a situation the query that will set the flag field back to 0 will bot be fired and hence the user would be seen as active in the system even though the user has already left the system.
When one company is viewing the profile of another company in my site I also need to show whether that representative of the company whose profile is being viewed in logged in the system at that time or not so that if the user wants then can send a message to them.
I need some advice on how can I achieve this in the best possible way, where I can display the total number the total number of correct logged in members
Thanks a lot!
