function hook_simple_fb_connect_registration in Simple FB Connect 7.2

This hook allows other modules to act on user creation via Facebook login.

There is also a Rules event triggered that can be used to react on user creation via Simple FB Connect.

The example code shows how to make an additional query to Facebook API in order to request user's first and last name and how to map these to corresponding Drupal user fields.

This example assumes that you have added fields "field_first_name" and "field_last_name" to User entity at admin/config/people/accounts/fields and that the length of these text fields is 255 characters.
