My webshop in wordpress needs to be modicified. I want the checkout page to automatically check the logged users info and fill out the billing info automatically. If a user is not logged in, then it ask to get the user logged in or continue without logging in. When the user log in, then it fill out the billing info automatically as well.
The billing info should be found and posssible to edit in the users page, I think it is called "your account" in Wordpress.
