I would like to trigger an external script function when a message in a specific forum is replied to, and be able to pass some information to the script (i.e. the post, or information about the post so it can be looked up in the database).
Then it would mean file changes on all places that are used to create new posts.
Easier would be to use RSS to pull it into your external script.
Is there anywhere I could put 1 or 2 changes that would trigger just whenever a reply or new thread happens, but not need to grab any data about it?
That way the script could read from the DB directly, or from RSS.. But not need to be on a crontab.. More real-time.
