按项目分列的信息-商家和PayPalExpress

Question

我正在使用ci-商人，我想做我的购物车结账与PayPal快递.

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，我将被重定向到PayPal，但是在items列中，我只看到一个唯一的项。

现在，我想添加按项目的描述，数量和价格.但是我不知道在哪里包括我的items数组，以及是否应该使用的格式。我在词商的文档里找不到。有人能解释我吗？

您只需要设置您的$params以包含所有您需要的字段，并且您需要确保您正在使用的是63.0或更高版本。

但是，这可能有点棘手，因为任何Express结帐流都可能包含多个付款，而每个付款都可能包含多个项，因此您最终将向params添加0、1、2等。

这是一个SetExpressCheckout的例子，其中包含两个项目的1付款。

        [L_PAYMENTREQUEST_0_NUMBER1] => 456
        [L_PAYMENTREQUEST_0_QTY1] => 1
        [L_PAYMENTREQUEST_0_ITEMURL1] => http://www.angelleye.com/products/456.php
        [L_PAYMENTREQUEST_0_ITEMCATEGORY1] => Digital
    )

当重定向到PayPal时，结果如下。

Answer 2

CI商人不支持在PayPal中开箱即出地列出订单。有一个拉请求支持这一点，但它不会合并到主人，直到我们解决一些税收计算和四舍五入的问题。

在正式支持之前，您可能希望尝试使用分叉版本来实现这一点，或者只需要自己编辑PayPal驱动程序来传递项数据。
