Question

到目前为止，我一直在使用Micah Carrick的PAYPAL IPN课程

web_accept

但现在其中一个客户想要将Recurring方法整合到其中。我尝试使用相同的东西，但不幸的是这次不太成功。我正在尝试连接到Paypal重复方法。以下是我尝试使用它的代码;

$paypalObj = new paypal_class();

$itemName = "My Product";
$itemNumber = $itemName . " - Premium ($amount$)";

$paypalObj->paypal_url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';// testing paypal url
//$paypalObj->paypal_url = 'https://www.paypal.com/cgi-bin/webscr';// Live paypal url

$paypalObj->add_field('cmd','_xclick-subscriptions');
$paypalObj->add_field('txn_type', "recurring_payment");
$paypalObj->add_field('product_name', "My Product Subscription - Monthly( $$amount )");
$paypalObj->add_field('desc', "My Product Subscription - Monthly( $$amount )");

$paypalObj->add_field('business', "test@yahoo.com");

$paypalObj->add_field('return', "http://".$serverName . "/buy-now.php");
$paypalObj->add_field('cancel_return', "http://".$serverName. "/return.php?action=cancel");
$paypalObj->add_field('notify_url', "http://" . $serverName . "/return.php?action=ipn");

$paypalObj->add_field('src', "1");
$paypalObj->add_field('sra', "1");
$paypalObj->add_field('a3', "$amount");
$paypalObj->add_field('t3', "M");
$paypalObj->add_field('p3', "1");
//$paypalObj->add_field('no_note', "1");
$paypalObj->add_field('currency_code', "USD");

$paypalObj->add_field('first_name', $firstName);
$paypalObj->add_field('last_name', $lastName);

$paypalObj->submit_paypal_post();

代码让我重定向到Paypal沙箱（因为我还在测试），但是当我登录到Paypal沙箱时，它会抛出这个错误：

您用于进入PayPal系统的链接无效。请查看该链接，然后重试。

Answer 1

我只知道我的代码背后的问题是什么。我只是用其他一些变量重写了代码，它运行良好。

$paypalObj = new paypal_class();


$customData = $firstName . ":";
$customData .= $lastName . ":";
$customData .= $emailId ;
$itemName = "MY_PRODUCT";
$itemNumber = $itemName . " - Premium ($amount$)";

$paypalObj->paypal_url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';// testing paypal url


$paypalObj->add_field('cmd','_xclick-subscriptions');
$paypalObj->add_field('business','MY_MECHANT_ACCOUNT');
$paypalObj->add_field('item_name',$itemName);
$paypalObj->add_field('item_number',$itemNumber);
$paypalObj->add_field('return', "http://" . $serverName . "/buy-now.php");
$paypalObj->add_field('cancel_return', "http://".$serverName. "/buy-now.php?action=cancel");
$paypalObj->add_field('notify_url', "http://" . $serverName . "/buy-now.php?action=ipn");
$paypalObj->add_field('no_note','1');
$paypalObj->add_field('currency_code','USD');
$paypalObj->add_field('custom',$customData);
$paypalObj->add_field('a3', "$amount");
$paypalObj->add_field('t3', "M");
$paypalObj->add_field('p3', "1");
$paypalObj->add_field('src', "1");
$paypalObj->add_field('sra', "1");

$paypalObj->submit_paypal_post();

Answer 2

我不相信你应该设置txn_type - 这是PayPal的IPN传回的值，而不是传递给它。

如何将Paypal IPN与经常性付款相结合？
