content_extra_field_weight() function in Drupal 7 I am porting a module to Drupal 6. I came across this function content_extra_field_weight(), what is the similar function in Drupal 7 for content_extra_field_weight()?
Invoke hook_field_extra_fields(), pass the result to  hook_field_extra_fields_alter() and look for weight keys in the result.
