I would like to create a select field with a list of registered users (use Display Name in list). I found the below code that creates a list of roles for the site which works great. I am not sure how to modify the code to get a list of registered users.

add_filter('acf/load_field/name=user_groups', 'populateUserGroups');

function populateUserGroups( $field )
{	
	// reset choices
	$field['choices'] = array();
	
	global $wp_roles;
	$roles = $wp_roles->get_names();
	
	foreach ($roles as $role) {
		$field['choices'][ $role ] = $role;
	}

	return $field;
}

I have not tested this, for more information see https://codex.wordpress.org/Function_Reference/get_users

add_filter('acf/load_field/name=user_groups', 'populateUserGroups');

function populateUserGroups( $field )
{	
	// reset choices
	$field['choices'] = array();
	
	$users = get_users();
	
	foreach ($users as $user) {
		$field['choices'][ $user->ID ] = $user->display_name;
	}

	return $field;
}

Thanks John for the help. I also appreciate your support on these forums. I am new to ACF and your code and comments have been very helpful with my project.

FYI: This can be done through the User field now
