这是paypal控制器代码：

public function __construct(){
    parent::__construct();
    $this->load->library('session');
    $this->load->library('cart');
    $this->load->helper('url');
    $this->load->helper('form');
    if (! $this->session->userdata('is_logged_in')){
        redirect('main/restricted');
    } else {
    $privilege = $this->session->userdata('privilege');
    if ($privilege == 'admin'){
        redirect('main/restricted');
    }
    }
    $this->load->helper("string");
}

public function do_purchase(){
    $config['business']             = 'phptesting2015-facilitator@gmail.com';
    $config['cpp_header_image']     = ''; //Image header url [750 pixels wide by 90 pixels high]
    $config['return']               = 'https://snt.website/ignite_project/payment/notify_purchase';
    $config['cancel_return']        = 'https://snt.website/ignite_project/payment/cancel_purchase';
    $config['notify_url']           = 'process_payment.php'; //IPN Post
    $config['production']           = FALSE; //Its false by default and will use sandbox
    //$config['discount_rate_cart']     = 20; //This means 20% discount
    $config["invoice"]              = random_string('numeric', 8); //The invoice id

    $this->load->library('paypal',$config);

    #$this->paypal->add(<name>,<price>,<quantity>[Default 1],<code>[Optional]);

    //$this->paypal->add('T-shirt',2.99,6); //First item
    //$this->paypal->add('Pants',40);     //Second item
    //$this->paypal->add('Blowse',10,10,'B-199-26'); //Third item with code

    $this->paypal->pay(); //Proccess the payment
}

public function notify_purchase(){
    $received_data = print_r($this->input->post(), TRUE);

    echo "<pre>".$received_data."</pre>";
}

public function cancel_purchase(){
    echo "Cancel Purchase";

}

}

我想知道如何从购物车中获取数据，以便我能够在paypal中添加值，以便用户可以继续使用paypal？请帮忙！

Answer 1

使用CI购物车库方法

$this->cart->total()

你得到这个总金额（价格），如果你想对此进行折扣，你需要为此制作一个独有的方法。

[编辑]

当您获得Paypal库和Curl（根据Paypal文档）解析它的总金额时，您可以使用Curl方法解析该值

curl -v -X 'POST' 'https://api.sandbox.paypal.com/v1/invoicing/invoices' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer <Access-Token>' \
-d '{
  "merchant_info": {
    "email": "dennis@sample.com",
    "first_name": "Dennis",
    "last_name": "Doctor",
    "business_name": "Medical Professionals, LLC",
    "phone": {
      "country_code": "001",
      "national_number": "5032141716"
    },
    "address": {
      "line1": "1234 Main St.",
      "city": "Portland",
      "state": "OR",
      "postal_code": "97217",
      "country_code": "US"
    }
  },
  "billing_info": [
  {
    "email": "example@example.com"
  }
  ],
  "items": [
  {
    "name": "Sutures",
    "quantity": 100,
    "unit_price": {
    "currency": "USD",
    "value": 5
    }
  }
  ],
  "note": "Medical Invoice 16 Jul, 2013 PST",
  "payment_term" :{
      "term_type": "NET_45"
  },
  "shipping_info": {
    "first_name": "Sally",
    "last_name": "Patient",
    "business_name": "Not applicable",
    "address": {
    "line1": "1234 Broad St.",
    "city": "Portland",
    "state": "OR",
    "postal_code": "97216",
    "country_code": "US"
    }
  }
}'

Answer 2

根据控制器中的代码判断，您可以在do_purchase()函数中使用您的paypal（我假设的库）通过循环购物车内容来添加产品：

foreach ($this->cart->contents() as $item) {
    $this->paypal->add($item['name'], $item['price'], $item['qty']);
}

$total = $this->cart->total();

您可以找到有关CodeIgniter购物车类in the docs的更多信息。

在一个完全不相关的注释中，您可以使用base_url()作为函数，而不是将字符串附加到它。例如，与<?=base_url('cart/remove/' . $item['rowid']);?>

相比，<?php echo base_url(); ?>cart/remove/<?php echo $item['rowid'] ?>更具可读性
