Here's what we'd like to do when create/edit node of specific type of content (we have 2 specific types, let's call them "type A" and "type B"):
- hide the title (= the user can change all fields but not the title)
- show a combo box to choose an item (lot of items, and this field is a long name)
- depending on the type of the content, when validating the node, update the title like this:
title = name of the item + " - " + type of the content
User creates a node of "type B". He chooses the item called "The item XYZ long name" and validates
=> the title of the node is auto-magically created:
The item XYZ long name - Type B.
Any idea how to do this (I don't know how to hide the title when creating/editing a node as well)?
