在遵循了位于paypal-payment-gateway-integration的教程之后
我现在要更改此设置，以便可以将单个项目传递给PayPal，而不是仅将总数量和价格传递给PayPal。
因此，仅从方法1澄清到方法2 How do I add PayPal Checkout to my custom shopping cart?
[方法1：将购物车总金额传递到PayPal您可以将购物车的总金额传递到PayPal的“立即购买”按钮代码中，就好像它是单项购买一样。
方法2：将单个项目传递到PayPal
我关注了Passing-Individual-Items-to-PayPal和我发现的其他链接。但是这些没有我要的答案。
我如何将下面使用上述方法1运行的代码转换为方法2。我已经将表格更改为：-
<input type="hidden" name="upload" value="1">
<input type="hidden" name="cmd" value="_cart">
但是后来不知道如何传递单个项目和数量。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

<?php
// Initialize the session
session_start();
// Check if the user is already logged in, if yes then redirect him to welcome page
if(isset($_SESSION["loggedin"]) && $_SESSION["loggedin"] === true){
}
else {
header("location: login.php");
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"] * $item["quantity"]);
}
}
}
if(!empty($_POST["proceed_payment"])) {
$name = $_POST ['name'];

if (! empty($cartItem)) {
foreach ($cartItem as $item) {
$shoppingCart->insertOrderItem ( $order, $item["id"], $item["price"], $item["quantity"]);
