Just so I’m on the same page here – I would use the acf/save_post action to collect the content from the acf fields in my custom post type, then using a function create posts depending on the specific fields?
Create new CPT post via WP Admin
Enter all fields
Click “Publish”, when this is clicked the action and function will be triggered and processed
CPT will be saved and other CPT posts created
I think this makes sense, but if I’m on the wrong path just let me know.
