Can someone suggest a way to get get a list of user-editable* fields in a node of a given content type? I'm trying to write a module which will set field defaults in nodes being created by Feed API -- including fields which do not exist in the feed, hence I need to know what's in the node, not what's in the feed. It also has to be different _per feed_, hence I can't just go by content type -- not that that is any easier. *By user-editable, I mean the actual data fields, not the meta-data fields. I don't want to mess with things like nid, vid, type, uid, status, etc. Rather, just any field which any module (e.g. CCK) might have added to a basic node to create a new content type. Obviously, I can look at the node object, but it's very flat; there's no way to tell user data from meta-data attributes. Calling content_fields() will get me the CCK-added fields, I think (I worry about the date module...). And I can hard-code the basic core node fields, if I have to. But I'd prefer a general solution. Advice? Ideas? Thanks, ..chris
