paypal - 每件商品的详细信息 ci-merchant 和 PayPalExpress

Question

我正在使用 ci-merchant，我想使用 PayPal Express 结账。

这是我使用的代码:

$this->load->library('merchant');
$this->merchant->load('paypal_express');
$settings = $this->merchant->default_settings();
$settings = array(
    'username' => 'bla bla bla.gmail.com',
    'password' => 'bla bla bla',
    'signature' => 'bla bla bla',
    'test_mode' => true);
$this->merchant->initialize($settings);
$params =array(
            'amount' => $this->cart->format_number($this->cart->total()),
            'currency' => 'EUR',
            'return_url' => 'https://www.example.com/checkout/payment_return/123',
            'cancel_url' => 'https://www.example.com/checkout',
            'description' => 'Esto es desc'
                    );

$response = $this->merchant->purchase($params);

使用上面的代码，我被重定向到 PayPal 就好了，但是在项目列中我只看到一个独特的项目。

现在我想添加每件商品的描述、数量和价格。但我不知道在哪里包含我的项目数组，以及我应该使用哪种格式。我在 ci-merchant 文档上找不到它。谁能给我解释一下？

您只需设置 $params 以包含使其正常工作所需的所有字段，并且您需要确保您使用的是 63.0 或更高版本。

不过，这可能有点棘手，因为任何 Express Checkout 流程都可能包含超过 1 笔付款，并且包含的​​每笔付款可能包含超过 1 件商品，因此您最终会添加 0、1、2 等。到参数。

这是 SetExpressCheckout 的示例，其中 1 笔付款包含 2 件商品。

重定向到 PayPal 时会产生以下结果..
