Hi @jacquesmivi
That’s because the repeater is posted as an array. If you want to see the values of the array, please try this code:
$ticket_date = print_r($_POST['acf']['field_5781107cd6eaa'], true);
To learn how to use an array, please take a look at this page: http://php.net/manual/en/language.types.array.php.

I hope this helps 🙂
