How to send the variables to database and retrieve it later

Hello, I have a flash design page for T shirt, and it is working like user can add the text or image from gallery on the Tshirt and rotate or drag them. So far , I wonder how to save those text and image in the database. And another thing I want to know is that how to save the imformation like where did the user drag the text or image to, because I need to show those content to the user when he login another time to see how does his product look like.

all in all, thanks very much if you have any idea about it.
