Question

这是我的付款表单和成功页面，用于获取付款并将付款数据存储到我的数据库。付款表单工作正常但success.php页面没有从paypal获取任何数据。我已经在paypal帐户中添加了IPN和自动返回URL，但它无法正常工作。请有人帮助我。

<?php
include 'dbConfig.php';

//Get payment information from PayPal
$item_number = $_GET['item_number']; 
$txn_id = $_GET['tx'];
$payment_gross = $_GET['amt'];
$currency_code = $_GET['cc'];
$payment_status = $_GET['st'];

//Get product price from database
$productResult = $db->query("SELECT price FROM products WHERE id = ".$item_number);
$productRow = $productResult->fetch_assoc();
$productPrice = $productRow['price'];

if(!empty($txn_id) && $payment_gross == $productPrice){
	//Check if payment data exists with the same TXN ID.
    $prevPaymentResult = $db->query("SELECT payment_id FROM payments WHERE txn_id = '".$txn_id."'");

    if($prevPaymentResult->num_rows > 0){
        $paymentRow = $prevPaymentResult->fetch_assoc();
        $last_insert_id = $paymentRow['payment_id'];
    }else{
        //Insert tansaction data into the database
        $insert = $db->query("INSERT INTO payments(item_number,txn_id,payment_gross,currency_code,payment_status) VALUES('".$item_number."','".$txn_id."','".$payment_gross."','".$currency_code."','".$payment_status."')");
        $last_insert_id = $db->insert_id;
    }
?>
  <h1>Your payment has been successful.</h1>
  <h1>Your Payment ID -
    <?php echo $last_insert_id; ?>.</h1>
  <?php }else{ ?>
  <h1>Your payment has failed.</h1>
  <?php } ?>

唱歌获得付款并且工作正常，但我没有收到IPN消息和任何数据到我的数据库？

Answer 1

您使用的代码更可能是用于PDT功能，而不是用于IPN。请查看下面的页面，了解IPN的示例代码。

此外，您可以查看下面的页面，了解这两个功能的比较及其详细信息。
