Related products

Hello,

in the single product page, i am using standard layout with tabs. I would like to show 4 related products in 4 columns and i am trying to use the following snippet:

add_filter('woocommerce_output_related_products_args', 'custom_related_products_args', 20);

function custom_related_products_args($args) {

  $args['posts_per_page'] = 4; // Mostra 4 prodotti correlati

  $args['columns'] = 4; // Disposti in 4 colonne

  return $args;

}

but it seems not to be working

Could you please have a look? Thanks a lot
