How to change term reference field according to role?

Question

I have the following challenge: I have 4 roles, let's call them Group1 ... Group4. I have different content types and I segregate access of those types using the Taxonomy Access Control module. So users from Group1 can only view and edit nodes that have term Group1.

Now, I have the challenge to change a term reference field of these content types automatically. So if a user from role Group1 creates a new node, that node will have a term reference field with term Group1.

I don't want users to edit on their own to avoid human errors.

Answer 1

All you need to do is create separate fields for respective roles. Use Field permissions module. Or if you want to have role wise access like from editor -> moderator -> pulisher etc. Use workfolw module.

Answer 2

Use the Rules module to create 4 similar rules (1 for each group), which would look like so (for Group1):

• Event: before saving content
• Condition: user has role Group1
• Action:
  1. Set a data value.
  2. Select the taxonomy term reference field to set.
  3. Select the taxonomy term 'Group1' (if needed: use the "Switch to the direct input mode" button to reveal the terms available in your taxonomy).

Repeat the above steps for Group2, 3 and 4 to create a similar rule.

You might want to try to consolidate those 4 (similar) rules in a single rule, by using the Rules Conditional module: the condition for each group would be replace by a similar "if condition" (contained in the rules action), and the Rules action for each group would only be executed if the "if condition" would be true. For a sample using the Rules Conditional module (for which there is not a lot of docu available), refer to my answer to the question "How to prevent a node being saved when using the Rules module?".
