Hi @simtwo
Could you please test it by changing how it is sorted from this:
array_multisort( $order, SORT_DESC, $value );
To this one:
array_multisort( $order, SORT_ASC, $value );
Also, could you please debug the value like this:
print_r( get_field('programmation', 99) );
Where ’99’ is the post ID.
Thanks 🙂
