About your first question, when your “desde” field is empty, it will return the today date same way if i do this:
$date = new DateTime();
You should make a condition to test if $date is not empty, like:
<?php $date = get_sub_field('desde', false, false);
if($date){
$date = new DateTime($date);
echo $date->format('d/m/Y');
} ?>
Second question…. not clear what you mean 🙂
