I am currently looking for a method to solve this problem.
I must be able to publish and edit a post back and front.
This post contains an ACF Date field that replaces the post date when one is saving.
For the back so no problem.
For the front:
The user must not be able to create a new post if there is already one at this date.
– Automatic daily post creation with a CRON (post_date = date today)
– Create other forms that only modify some fields of the form but not the post update (update post meta). But problem if a user edited at the same time back.
– Manual creation of the post back and front
– If a post exists with this date -> returns to edition.
If you think of other solutions …
Thank you so much !
