Import Facebook fields to Joomla without CB or JS

Hi,

I installed the component and configured it and it works great.
I´d like to import a few Facebook fields but I´m using an extension that does not support Community Builder or JomSocial .

I have set up new fields in the jos_user table in the database and I made a custom registration page that includes them.

I need to import information from Facebook such as hometown,gender,age etc. into these db fields.

Has this been discussed somewhere in the forum before and if so can you please show me a link, I havent found any threads.

I have decent knowledge in PHP and I you can point me in the right direction I could probably figure this out.

Please advise.

Best Regards
Ivar Rafn
