XF 1.4 Use page criteria to display notice within locked threads?

[Joe Link]

I'd like to display a notice (actually a popup using @Chris D's add-on) when a user views a thread which is locked, within specific nodes. I believe I could do this with the page criteria tab, but after playing around for an hour I can't seem to figure it out

 

[Chris D]

There's no criteria that matches a closed thread. It would require custom development or an add-on (various add ons exist for adding new criteria but I'm not sure if any of them add that specifically)

Thanks for the quick reply Chris.

Can you comment on the difficulty of writing such an add-on?

 

[Chris D]

Not very. The thread record would need to be available to the page container which isn't too difficult to do. Then the criteria checks would have the thread record available so you can read its closed state and act accordingly.
