I'm publishing my game soon on the instant game platform of facebook but I'm still stuck with how to get users' info when the game loads, I've looked around and found that there is some function in the index.html file that already calls FBInstant and retrieves the user information such as name and email.
is there a way to retrive these data or should I define another function in index.html then calls in from the events ? I have no prior experience with anything related to html and web stuff so I'm clueless on how to solve this issue.
