I’m trying to use a REST filter to require a certain parameter is set.
Using custom taxonomies and custom posts I’ve been able to make it so when I request
That the only
Cars that come back are ones with a
visible_to taxonomy of 123.
However when someone asks for
I want to throw an error, saying that ?visible_to needs to be set.
I’ve tried hooking into
rest_pre_dispatch, and some others. Each only fires when I have
?visible_to set in the URL, without them the hooks don’t fire.
For example, I would expect this to fire on every REST request
But it will only return a WP_Error on
Run without that filter being hit.
Can someone explain why this would be the case and what I can do to avoid it?
I’ve also tried specific filters like
rest_prepare_car but I couldn’t get it to fire at all.
