【问题描述】：
我使用了this_for_reference（效果很好）。
我面临的问题： 当我尝试使用 CodeIgniter 实施 same 以使用 PayPal 进行购物车付款时，我可以完成付款交易。 IPN 消息是在 PayPal 端生成的 [即时付款通知 (IPN) 详细信息]。但是我无法使用通知 URL 或下面提供的成功 URL 检索 IPN 消息，因此数据库没有得到更新。
这是视图文件，我在其中将商品添加到购物车，然后添加到 PayPal 付款。
<div class="row">
<?php if(!empty($products)): foreach($products as $row): ?>
<div class="thumbnail">
<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<!-- Identify your business so that you can collect the payments. -->
<input type="hidden" name="business" value="{My PayPal email ID}">
<!-- Specify a PayPal Shopping Cart Add to Cart button. -->
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="add" value="1">
<!-- Specify details about the item that buyers will purchase. -->
<input type="hidden" name="item_name" value="<?php echo $row['name']; ?>">
<input type="hidden" name="item_number" value="<?php echo $row['item_number']; ?>">
<input type="hidden" name="amount" value="<?php echo $row['price']; ?>">
<input type="hidden" name="currency_code" value="USD">
<!-- Specify URLs -->
<input type='hidden' name='cancel_return' value='http://{MyDomain}/paypal/cancel'>
<input type='hidden' name='return' value='http://{MyDomain}/paypal/success'>
//Notification URL is actually "http://{MyDomain}/paypal/ipn",
but it's **not a typo error** in my actual code.
I still face issues, mentioned in my Question.
{Preston PHX} It was a good catch//
<input type='hidden' name='notify_url' value='http://{MyDomain}/paypal/ipn'>
<!-- Display the payment button. -->
<input type="image" name="submit"
src="https://www.paypalobjects.com/webstatic/en_US/i/btn/png/btn_addtocart_120x26.png"
alt="Add to Cart">

PayPal成功函数
public function success(){
$txn_id = $_GET['tx'];
$payment_gross = $_GET['amt'];
$currency_code = $_GET['cc'];
$payment_status = $_GET['st'];
if(!empty($txn_id)){
//Check if payment data exists with the same TXN ID.
$paymentResult = $this->db->query("SELECT * FROM payment WHERE txn_id = '".$txn_id."'");
/* if($paymentResult->num_rows > 0){
//payment information
$paymentRow = $paymentResult->fetch_assoc();
$payment_id = $paymentRow['payment_id'];*/
if($paymentResult->get()->num_rows() > 0){
//payment information
foreach($paymentResult->get()->result_array() as $row)
{
$payment_id = $row['payment_id'];
}
$payment_id = $paymentRow['payment_id'];
//order items details
$orderItemResult = $this->db->query("SELECT p.name, i.quantity, i.gross_amount FROM order_items as i LEFT JOIN products as p ON p.id = i.item_number WHERE payment_id = '".$payment_id."'");
//pass the transaction data to view
//$this->load->view('paypal/cartsuccess', $data);
}
}
}
并在视图文件中显示结果。
