I have a content type "Page" and one of its fields is a term reference to the taxonomy term "Page Type"
Another field is "Expiry Date"
The page type starts off as "Open Consultation", but I need it to automatically change the term reference to "Closed Consultation" if the "Expiry Date" has passed.
I've been a developer for years, but I'm still quite new to Drupal (7)... I know the GUI, but not php or which files to override (if that is the answer)
So, I need a basic explanation of how to achieve this. Thanks !
