How to get boxes to auto populate with the contact info of the user who opens a ticket in ESS

Hello, 

I'm trying to get the contact name, Location, Contact Number of the user to auto fill when they open a ticket on the Submit a Request page on ESS page. Out of the box it auto populates the ID of the user so I know it's possible I just don't know how to get it set up.

Thanks in advance
