Hello,
Your code needs to be improved Use next code snippet instead of your one
function etheme_child_product_shipping_banner() { global $product; $shipping_class = $product->get_shipping_class(); switch ( $shipping_class ) { case 'free-shipping': echo 'Free shipping on this item'; break; case 'flat-rate': echo 'Flat rate shpping $10'; break; } } add_action('woocommerce_before_single_product', 'etheme_child_product_shipping_banner', 20 );
Result: https://prnt.sc/rLBkW2B8iuG4
