I paste this :
<?php echo '<pre>';
print_r( get_field('media-test') );
echo '</pre>'; ?>
“media-test” is the name of the field displayed on a media in the my media library in the admin panel.
I selected a custom post displayed in the field, but when I use the code from post object in the PHP of my custom post single template, nothing is retrieved.
The gallery field is a good way, I will use it if the first option doesn’t work.
