Question

在 paypal notify_url 页面中，当我使用 cmd 值作为 _cart 时，我没有得到任何值。如何在 notify_url 页面中获取交易详情

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="POST" name="_xclick" id="paypal_form">
<input type="hidden" name="upload" value="1" />
<input type="hidden" name="cmd" value="_xclick" />
<!-- The business email address, where you want to receive the payment -->
<!--<input type="hidden" name="business" value="yesidealpayment@gmail.com" />-->
<input type="hidden" name="business" value="arun_1260247381_per@galtechsupport.us" />
<!-- The customer email address -->

<input type="hidden" name="item_name_1" value="<?php echo ucfirst($couponname); ?>" />

<input type="hidden" name="amount_1" value="<?php echo $total_payable_amount; ?>" />
<!--<input type="hidden" name="currency_code" value="AUD" />-->
<input type="hidden" name="currency_code" value="USD" />

<input type="hidden" name="amount" value="25.58" /> 
<!-- Where you want to return after PayPal Payment -->
<input type="hidden" name="return" value="http://yes-i-deal.com.au/test/paypal_ipn.php" />
<!-- A back-end notification send to the specific page after successful payment  -->
<!--<input type="hidden" name="notify_url" value="http://yes-i-deal.com.au/test/paypal.php" />-->
<input type="hidden" name="notify_url" value="http://yes-i-deal.com.au/test/paypal_ipn.php" />
<!-- Where you want to return after cancel the PayPal Payment  -->
<input type="hidden" name="cancel_return" value="http://yes-i-deal.com.au/" />
<input type="hidden" name="custom" value="<?php echo $coupon_id."_".$userid;?>" />  




            <input type="image" name="submit"   src="http://yes-i-deal.com.au/themes/green/images/Buy-Now-Button.png" />
</form> 

在我的 notify_url 页面中，我得到的值是

 session_start(); 
require("ipn_cls1.php");
 $paypal_info = $_POST; 
print_r($paypal_info); 
$paypal_ipn = new paypal_ipn($paypal_info); 
$payment_status = trim($paypal_info['payment_status']); // Si Completed : tout est OK echo 
$payment_amount = trim($paypal_info['mc_gross']);

Answer 1

在我当前的项目中，paypal 自适应支付也有同样的问题。我已经给了我的

notify_url 为http://mysite.com/payment-success。在这个页面中，我只是编码

$request = $_POST;

mail('myid@myaccount', $request);

然后我将交易结果发送到我的邮箱查看。

注意，在我的邮件中，我可以看到交易结果，如果我插入数据库，它正在插入，但我无法在我的页面中看到交易结果。尝试将交易结果发送到您的邮箱。

创建 paypal_ipn.php 文件并在其中放置 php 代码。

    // Response from Paypal
    // read the post from PayPal system and add 'cmd'
    $req = 'cmd=_notify-validate';
    foreach ($_POST as $key => $value) {
        $value = urlencode(stripslashes($value));
        $value = preg_replace('/(.*[^%^0^D])(%0A)(.*)/i','${1}%0D%0A${3}',$value);// IPN fix
        $req .= "&$key=$value";
    }

    // assign posted variables to local variables
    $data['item_name']          = $_POST['item_name'];
    $data['item_number']        = $_POST['item_number'];
    $data['payment_status']     = $_POST['payment_status'];
    $data['payment_amount']     = $_POST['mc_gross'];
    $data['payment_currency']   = $_POST['mc_currency'];
    $data['txn_id']             = $_POST['txn_id'];
    $data['receiver_email']     = $_POST['receiver_email'];
    $data['payer_email']        = $_POST['payer_email'];
    $data['custom']             = $_POST['custom'];
    $data['invoice']            = $_POST['invoice'];
    $data['paypallog']          = $req;

    // post back to PayPal system to validate
    $header = "POST /cgi-bin/webscr HTTP/1.0\r\n";
    $header .= "Content-Type: application/x-www-form-urlencoded\r\n";
    $header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
    $fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30); 

    if (!$fp) {
        // HTTP ERROR
    } else {    


        fputs ($fp, $header . $req);
        while (!feof($fp)) {

            $res = fgets ($fp, 1024);
            if (true || strcmp($res, "VERIFIED") == 0) {

            // Validate payment (Check unique txnid & correct price)
            $valid_txnid = check_txnid($data['txn_id']);
            $valid_price = check_price($data['payment_amount'], $data['item_number']);
            // PAYMENT VALIDATED & VERIFIED!
            if($valid_txnid && $valid_price){

            if ($data['invoice']=='basic') {

        } elseif ($res=='INVALID') {

                // PAYMENT INVALID & INVESTIGATE MANUALY!

        }

    }
