	) );
	echo '</div>';
}

add_action( 'woocommerce_process_product_meta', 'ws_save_fields', 10, 2 );
function ws_save_fields( $id, $post ){
 
	if( !empty( $_POST['winner_select'] ) ) {
		update_post_meta( $id, 'winner_select', $_POST['winner_select'] );
	} else {

Since this requires custom coding, I’m going to leave it open for a bit to see if anyone is able to chime in to help you out.

For additional assistance on this topic, we recommend getting in touch with one of the customization experts listed on the WooCommerce Customizations Page.

You can also visit the WooCommerce Facebook group or the #developers channel of the WooCommerce Community Slack. We’re lucky to have a great community of open-source developers for WooCommerce, and many of our developers hang out there, as well.

Cheers!
