Hi again. Many thanks but sadly I have some others questions….
1) Inside the ‘acf/save_post’ hook the statement…
$_POST['acf']['field_abc123'];
… retrieve the new posted value of a certain field.
Consider if the admin doesn’t write any new data inside that field in that post saving… that post value would fall back to the old posted value, or it will be simply empty?
2) What do you mean that the gallery field would not return what I expect? Is that
inconsistency normal?
Many thanks!
