+1 (with lifetime license). ACF Pro 6.2.8
I’m having a similar issue with a custom taxonomy field and acf_form(). The taxomnomy field is showing the right value in the backend, but radio buttons are empty on the form on the frontend. That is, until I save the post again (either from the front- or backend).
I found out that when using ACF Pro (5.1.5) does already convert the date field’s content to a string, so you will get a fatal error (Call to a member function format() on a non-object
) when using
$date = DateTime::createFromFormat($format_in, get_field('date-start'));
What does work is
$date = new DateTime( get_field('date-start') );
