Question

我正在使用ci-merchant，我想用PayPal Express结账。

这是我正在使用的代码：

$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，但在items列中我只看到一个唯一的项目。

现在我想添加每件商品说明，数量和价格。但我不知道在哪里包含我的items数组，我应该使用哪种格式。我在ci-merchant docs上找不到它。有人可以解释一下吗？

Answer 1

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

但是，这可能有点棘手，因为任何快速结账流程都可能包含超过1个付款，并且每个付款可能包含多个项目，因此您最终会添加0,1,2等。参考。

以下是SetExpressCheckout的示例，其中包含1个付款，其中包含2个项目。

        [L_PAYMENTREQUEST_0_ITEMCATEGORY1] => Digital
    )

重定向到PayPal时会导致以下情况。

Answer 2

CI Merchant不支持开箱即用的PayPal中的商品订单商品。有pull request支持这一点，但在我们解决一些税收计算和四舍五入问题之前，它不会合并为主。

在正式支持之前，您可能需要尝试使用分叉版本来实现此目的，或者只是自己编辑PayPal驱动程序以传递项目数据。

每件商品详情ci-merchant和PayPalExpress
