Hi
I’m using Repeater with Field type “Select” and object “Users” for Author on Post.

I got problem that the list users show when select a Author is not sorted.

Is there anyone can help me how to sort that list Author by alphabet on Post backend page?
Thanks.
There are filters in the user field that will let you change the sort order, the code in acf looks something like this
// filters
$args = apply_filters("acf/fields/user/query", $args, $field, $options['post_id']);
$args = apply_filters("acf/fields/user/query/name={$field['_name']}", $args, $field, $options['post_id']);
$args = apply_filters("acf/fields/user/query/key={$field['key']}", $args, $field, $options['post_id']);
$args is the same as used in the wp function get_users() https://codex.wordpress.org/Function_Reference/get_users
add_filter('acf/fields/user/query/name=user_field_name', 'change_user_order_by', 10, 3);
function change_user_order_by($args, $field, $post_id) {
$args['orderby'] = 'display_name';
return $args;
}
