Question

我正在使用支付网关 PayPal 制作电子书在线商店。在用户购买我的书之前，我希望他们注册并且我想将他们的信息保存到我的数据库中。这是我从developer.paypal.com 复制的代码。

当用户提交表单时，它会将我带到 PayPal 结账处

这很好，这就是我想要的，但我也想将他们签名的表单字段插入到我的数据库中，所以我稍微更改了代码。这是我的视图代码：

我的控制器代码：

  public function the_buyer(){

    $data['buyer_first_name'] = $this->input->post('buyer_first_name');
    $data['buyer_last_name']  = $this->input->post('buyer_last_name');
    $data['buyer_email']      = $this->input->post('buyer_email');
    $this->load->model('buyers_db/buyers');
    $this->buyers->insert($data);
    redirect('https://www.paypal.com/cgi-bin/webscr');

}

我的型号代码：

public function insert($data){

        $this->db->insert('buyers',$data);

    }

现在当用户提交表单时，字段值正在插入到我的数据库中，但现在页面正在将我重定向到这个主页

Answer 1

表单需要直接提交给 PayPal，而不是您的网站。您将需要使用notify url 或return 链接来处理付款并在数据库中插入任何信息。

有关PayPal IPN的更多信息，我建议您查看this link。

您需要在表单的自定义字段中包含要存储的任何数据。我建议，存储类似 user_id 或加密的 user_id 的内容，以便当notify ping 回您的网站时，您可以读取custom 中的内容，并使用它将数据插入数据库。请注意，此字段可能被篡改，因此请记住对其进行清理或加密，以便用户无法更改数据。

Answer 2

我没有重定向到正确的网址

 redirect('https://www.paypal.com/pe/cgi-bin/webscr?cmd=_flow&SESSION=S-A8TQJiOMvvMRh8VUV6-8W01hNHYgkK0ZVirABunW_IjHIcFecUT9cfGxm&dispatch=50a222a57771920b6a3d7b606239e4d529b525e0b7e69bf0224adecfb0124e9b61f737ba21b08198acc59b45c1b5383c3fbf91319c9514c0');
