Quantity discount on 2nd item only in Woocommerce

Question

I want to achieve a global discount for all products but only for the 2nd product item.

What do I mean? If the customer buys \"Jacket\" no discount is given.

Answer 1

foreach ( $cart->cart_contents as $key => $values ) {
                    $product_id = $values['product_id'];

                    foreach ($cart->get_cart_item_quantities() as $key => $value){
                        //print_r($key[1]);
                        $key = array_keys($cart->get_cart_item_quantities())[1];
                        if($key == $product_id){

                            $product = wc_get_product($product_id);
                            $get_price = $product->get_price();
                            $new_price = $get_price / 2;
                            $values['data']->set_price($new_price);

                            break;
                        }
                    }
                }
//Please try this, it will work for sure in same above hook :)
