WooCommerce - Show Random Products

Alright folks here is a bit of code I am using for mine its for recent products but is doing the job. Just add to page you want to show them on.

[recent_products per_page="4" columns="4" orderby="rand" order="rand"]

Try this. Paste code into functions.php Go to wp-admin/ Woocommerce > Settings > Products > Display View settings drop down order by random will be a new option. *note: it will be the the last option.

// Shop random order. View settings drop down order by Woocommerce > Settings > Products > Display
add_filter( 'woocommerce_get_catalog_ordering_args', 'custom_woocommerce_get_catalog_ordering_args' );
function custom_woocommerce_get_catalog_ordering_args( $args ) {
    $orderby_value = isset( $_GET['orderby'] ) ? woocommerce_clean( $_GET['orderby'] ) : apply_filters( 'woocommerce_default_catalog_orderby', get_option( 'woocommerce_default_catalog_orderby' ) );
    if ( 'random_list' == $orderby_value ) {
        $args['orderby'] = 'rand';
        $args['order'] = '';
        $args['meta_key'] = '';
    }
    return $args;
}
add_filter( 'woocommerce_default_catalog_orderby_options', 'custom_woocommerce_catalog_orderby' );
add_filter( 'woocommerce_catalog_orderby', 'custom_woocommerce_catalog_orderby' );
function custom_woocommerce_catalog_orderby( $sortby ) {
    $sortby['random_list'] = 'Random';
    return $sortby;
}

This works for me:

<?php
    $args = array(
        'posts_per_page'   => 1,
        'orderby'          => 'rand',
        'post_type'        => 'product' ); 

    $random_products = get_posts( $args );

    foreach ( $random_products as $post ) : setup_postdata( $post ); ?>
    <li>
        <a href="<?php the_permalink(); ?>">
    <?php the_title(); ?></a>
    </li>
<?php endforeach; 
wp_reset_postdata();
?>
