Thank you, but…
I tried to recover the username but nothing is displayed.
$userID = get_field('user2'); $theuser = get_userdata($userID); echo 'Username: ' . $theuser->user_login;
I noticed with the code the_field(‘USER2’) showed that all of the information user.
But with $user2 = get_field(‘USER2′) and echo $user2; nothing is displayed. Even with this code where it does not work:
$user2 = ’20’; (id of a user) $theuser = get_userdata($user2) does not retrieve the value.
So if I try $theuser = get_userdata(20); echo $theuser->user_login; it’s ok…
