Site optimisation - How to save a visitor site options?
I'd like to learn how I'd save a users option to a MySQL database instead
of using cookies to save this specific visitor data.
e.g.
On the landing page, is a red box 300 by 300 pixels, once the visitor
hovers the Blue, Green, Yellow it'll switch from red(default) to the color
chosen.
How would I save this choice from an Offline user to database then if
needed retrieve it?
