I need to update custom fields of a custom post type.
Right now I am using the classic route to update the post so I can update the title, content… but no custom fields.
What would be the best way to do that? From what I have read so far the solution could be in using the hook save_post but I do not see how to pass the new value of the custom field (the new value comes from a textarea on the front).
Thank you for your help
acf_form() is my answer. Thank you
