更改 WooCommerce 代码以增加促销活动

Question

我在 WordPress WooCommerce 中有一个代码，一旦您使用 ID 购买产品： 1561、1919、1568、1562、1563、1564、1565、1566、1567 所以，第二个产品是 NIS 10。

优惠商品仅限ID 1561的商品 代码运行得很好，但是一旦我想要有多个促销，它就不起作用了。

例如： 如果您购买两种产品，那么我希望客户能够以 10 新谢克尔的价格获得两次产品 1561 如果您购买五种产品，那么我希望客户能够以 NIS 10 收到五倍产品 1561 等等...

add_action('woocommerce_before_calculate_totals', 'change_second_item_price', 10, 1);

function change_second_item_price($cart) {
    if (is_admin() && !defined('DOING_AJAX')) {
        return;
    }

    $discounted_product_id = 1561;
    $new_regular_price = 10; // NIS 10

    // Initialize count for the target products
    $target_product_count = 0;

    // Loop through cart items
    foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
        $product_id = $cart_item['product_id'];

        // Check if the product is one of the target products
        if (in_array($product_id, array(1561, 1919, 1568, 1562, 1563, 1564, 1565, 1566, 1567))) {
            $target_product_count += $cart_item['quantity'];

            // Check if it's the discounted product and change the regular price
            if ($product_id == $discounted_product_id && $target_product_count >= 2) {
                $cart_item['data']->set_regular_price($new_regular_price);
                $cart_item['data']->set_price($new_regular_price); // Also set the current price to the regular price
                break; // Stop the loop after changing the regular price for the second item of the discounted product
            }
        }
    }
}

帮助更改代码。

我认为你需要先计算最大折扣产品数量，然后为适当的产品设置价格：

add_action('woocommerce_before_calculate_totals', 'change_second_item_price', 10, 1);

function change_second_item_price($cart) {
    if (is_admin() && !defined('DOING_AJAX')) {
        return;
    }

    $discounted_product_id = 1561;
    $new_regular_price = 10; // NIS 10

    // Initialize count for the target products
    $target_product_count = 0;

    // Loop through cart items
    foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
        $product_id = $cart_item['product_id'];

        // Check if the product is one of the target products
        if (in_array($product_id, array(1561, 1919, 1568, 1562, 1563, 1564, 1565, 1566, 1567))) {
            $target_product_count += $cart_item['quantity'];
        }
    }

    // Loop through cart items again, to find the discounted product
    foreach ($cart->get_cart() as $cart_item_key => $cart_item) {
        $product_id = $cart_item['product_id'];

            // Check if it's the discounted product and change the regular price
        if ($product_id == $discounted_product_id && $target_product_count >= $cart_item['quantity']) {
            $cart_item['data']->set_regular_price($new_regular_price);
            $cart_item['data']->set_price($new_regular_price); // Also set the current price to the regular price
        }
    }
}

请记住，这允许客户始终以 10 新谢克尔购买 1561。我认为这是您的意图，但我不确定。
