Order users by random not working?

Question

So I'm trying to list my wordpress user id's each time in a random order.

Right now I have this, but for some reason, 'orderby' => 'rand' is not randomizing the list.

<?php 

$args  = array(
    'meta_key' => 'active',
    'meta_value' => 'yes',
    'number' => 99999,
    'orderby' => 'rand',
);
 
$my_user_query = new WP_User_Query( $args );
$publishers = $my_user_query->get_results();
 
if ( ! empty( $publishers ) ): ?>

<?php foreach ( $publishers as $publisher ): 
        
setup_postdata( $publisher )
        
?>


<?php echo $publisher->ID; ?>


<?php endforeach; ?>
    
<?php wp_reset_postdata(); ?>

<?php endif; ?> 

I have tried 'order' => 'rand' which is not correct as to my knowledge.

To make sure that the above array works, I have tried:

'order' => 'ASC' and 'order' => 'DESC'

both worked great.

I assume there's something wrong with my rand code line.

I have also heard that it's possible to use shuffle($users);, but I have no idea where and how to implement.

Need help.

Answer 1

Ok, so I found this solution in other thread which did worked:

Added this to functions.php:

add_action( "pre_user_query", function( $query ) {
    if( "rand" == $query->query_vars["orderby"] ) {
        $query->query_orderby = str_replace( "user_login", "RAND()", $query->query_orderby );
    }
});

It sorts users by a random order now!
