Based on couple of features I require to restrict/disable access to certain field based on other fields while editing the node.

The problem is that in Rules module, there's no "While editing an existing node" event.

What I want is to set an action for the user while editing the node.

  • why you don't try it programmatically?

  • Well I'm working on a workflow system for managing an article submission contest, I need to disable the access to a file field and enable access to another file field after a certain state transition of workflow. So this is basically what I need: If the current state of node is "approved", then disable access to field "summary_article" for instance. thanks "dadash"

You're right, there is no such event like "While editing an existing node". Probably because an event is something that takes like a fraction of a second, while editing may take minutes (hopefully not hours!).

However, you might get it to work by implementing an "edit-in-progress" (= EIP) feature using the Flag module, combined with using the Rules module. Similar to what I described in my answer to "Can the Flag module be used to lock content while editing to prevent concurrent edits?" (BTW, that question is a variation of yours, I don't think it's a duplicate though ...).

After you'd have such EIP-flag available, it should be straight forward to use it in appropriate Rules to "restrict/disable access to certain fields" (eg based on a data comparison to validate selected field values (using their before and after save values).
