How to append fields to published node in drupal? A node once published should not be edited, but extra fields can be added to that node. How can i do it? For example , lets say i have a content type called 'employee'. Once i create this content i cannot edit that node but can only add more information to that node. this extra information must be stored in the node's column. Is it possible ? or is there any other way?
guess its possible with a combination of hook_form_alter and hook_nodeapi

Do check out these methods... hope it helps...
