I have programatically created some cck fields with this function:
and I tried to delete them with this:
content_field_instance_delete($field_name, 'product', FALSE)
However, this didn't actually delete the cck field from the Product types database table. The fields didn't show up on the UI edit page but they still exist in the database, which is causing me some issues. How can I systematically make sure the database entry is wipes as well?
