How do I send a privatemsg to all users that have flagged a node using Rules?

Question

I am using the Privatemsg module, Flag module and Rules module.

I wonder if using Rules I could send a private message to all the people who have flagged a specific node when a new comment is posted.

Thus, the flag would act like a subscription for new comments notification.

Answer 1

1. Create a new rule triggered on After saving a new comment`.
2. No conditions necessary; set them up only if you require something specific.
3. Actions:
   • Fetch users who have flagged a node
   • Loop through those users (argument will be populated automatically)
   • Under that loop create a new action "Send a message". This will require you to have "Privatemsg Rules Integrations" module enabled.
