Thanks for your answer.
I have a form to pick one or * dates (repeater field), and i wish to send this by email.
So I try to construct ‘$ticket_date’ with the different walues.
If I send “$_POST[‘acf’][‘field_5781107cd6eaa’]” I just have “Array” in my email.
If I send have_rows($_POST[‘acf’][‘field_5781107cd6eaa’]) I got nothing in my email.
