I created another topic recently asking people to test my Facebook register but I realized a problem so sorry about that. I have a question that either the Facebook doc doesn't mention or I cannot find... I can use the Facebook register to insert the user into my site's database correct? I do not understand how Facebook login and register will work with just javascript alone unless the custom PHP is in fact necessary for a site to work properly. So lets say that I do use the Facebook register and it inserts the user into my database... how can I use the Facebook login then or will they have to login to the site the normal way using my site's own login? For some reason when I first looked at that Facebook feature I thought it would just fill out my site's forms and then the rest would be handled by the site's script but it looks like it is totally separate.
