If you are familiar with Content Profile Drupal Module, you noticed that this module generates a tab(s) or subtab(s) for edition mode. This behavior is acceptable, but a common request is to be able to put all fields in one big form, but with this option each section has its own submit button.
Well this is my solution for this request.
1. Create a PHP block for each content of profile content type, i.e user_shipping_address_page.
