【问题描述】：
按照这里的教程paypal-payment-gateway-integration
我现在想更改此设置，以便我可以将单个项目传递给 PayPal，而不仅仅是总数量和价格。
所以只是为了澄清从方法1到方法2How do I add PayPal Checkout to my custom shopping cart?
方法 1： 将购物车总金额传递给 PayPal 您可以将购物车的总金额传递给 PayPal 的“立即购买”按钮代码，就好像它是单项购买一样
方法 2： 将单个项目传递给 PayPal
我已关注Passing-Individual-Items-to-PayPal 和我找到的其他链接。然而，这些没有我正在寻找的答案。
如何将下面使用上述方法 1 的代码转换为方法 2。 我已经将表格更改为：-
<input type="hidden" name="upload" value="1">
<input type="hidden" name="cmd" value="_cart">
但后来不知道如何传递各个项目和每个项目的数量。我假设我需要在这里的某个地方添加一个循环。
下面的完整代码

exit;
}
require_once "ShoppingCart.php";
$member_id = 2; // integrate authentication module here to get logged in member
$shoppingCart = new ShoppingCart();
/* Calculate Cart Total Items */
$cartItem = $shoppingCart->getMemberCartItem($member_id);
$item_quantity = 0;
$item_price = 0;
if (! empty($cartItem)) {
if (! empty($cartItem)) {
foreach ($cartItem as $item) {
$item_quantity = $item_quantity + $item["quantity"];
$item_price = $item_price + ($item["price"] * $item["quantity"]);
