Thanks for your help Lanceal.
I can insert into databases and get info from databases easily enough. Your capx and the tutorials led me through it. The problem is updating info in a database.
I think it is the session part that thwarts me.
A session is basically a cookie or token that maintains a connection between the browser and server, that way when you login to a website and go from one page to another (http://somesite.com/index.php to somesite.com/myprofile.php) the server remembers your info on the website's database. Otherwise you would have to login to view each individual page of a website (like facebook or even scirra.com)
I will try stackoverflow. I just hope someone on there has knowledge of C2 AJAX requests. I don't think anything is off in my php code.
