//For example, to check for the Shipping Class ‘free-shipping’, use this:


if ( cart_has_product_with_shipping_class( 'free-shipping' ) ) {
 
    // Yes, the cart has a product with the 'free-shipping' Shipping Class.
 
} else {
 
    // The cart does NOT have a product with the 'free-shipping' Shipping Class.
