How to set random order for products in WooCommerce

In order to set random order for products, you should perform the following:

  1. Navigate to the following directory in your cpanel or FTP: wp-content/themes/themeXXXXX/includes, locate a custom-function.php file, and click an Edit button (or edit it with the help of a text editor).
  2. Paste the following piece of code to the bottom of the file before the last ?>:
    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;
    }
  3. Save the changes and navigate to the following directory in your WooCommerce Settings: Products–>Display.
  4. Check out the Random option under Default Product Sorting directory.
