I removed the ajax altogether to test this another way. I used an empty form submit with a function that is hooked to init that checks posted data and runs if it finds a value.
I also simplified the function so it only updates the field with the user id.
function add_volunteer() {
if ( isset( $_POST['add-volunteer'] ) && '1' == $_POST['add-volunteer'] ) {
$cleanup_id = $_POST['cleanup_id'];
$user_id = get_current_user_id();
update_field('field_57e89bd93b402', $user_id, $cleanup_id);
}
}
add_action( 'init', 'add_volunteer' );
I also tested it with the field set to select multiple values and select single value.
I’m still seeing the same issue though. Is it possible that this is a bug?
