I am using Belvg facebook connect for facebook login, Now i am developing other module where i want to use the facebook user session in that module how can i check whether user is logged in using facebook account. if user logged in with facebook account i would like to fetch his friends list. Kindly provide me some suggestions on this.
By I dont think you will be able to get the friends list.
You should be able to use the Magento Session to check if logged in, and you as far as I believe the Belg plugin also stores the connect data in the database (prefixed with belg) with you would need to add inside the query.
I am looking for a snippet of code that we used to complete this which may help you get the solution.
