Get order of a content type's fields

Question

When I manage fields in content type edition I can put them in order. How could I retrieve this information to use it in a custom module. In Database there is no any column which saves weight order information of fields as they appears in "Manage fields" tab in content type edition.

Answer 1

Use field_info_instance()

  $entity_type = 'node';
  $field_name = 'body';
  $bundle_name = 'article';
  $body = field_info_instance($entity_type, $field_name, $bundle_name);

Which gives you access to numerous config/settings

  $body_weight = $body['display']['default']['weight'];
