Question

我有以下Paypal付款表格：

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="******">
<input type="hidden" name="item_name" value="******">
<input type="hidden" name="item_number" value="1">
<input type="hidden" name="amount" value="25">
<input type="hidden" name="no_shipping" value="0">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="bn" value="PP-BuyNowBF">
<input id="afield" type="text" placeholder="Name"</input>
<input id="afield" type="text" placeholder="Email Address"</input>
<!-- Saved buttons display an appropriate button image. -->
<input type="image" name="submit"
src="https://www.paypalobjects.com/en_US/i/btn/btn_buynow_LG.gif"
alt="PayPal - The safer, easier way to pay online">
<img alt="" width="1" height="1"

我的问题是，如何获得两个输入（id：afield），以便在用户付款后返回我的网站时可以保存它们，以便使用。我正在使用PHP。

谢谢

Answer 1

这是我过去处理此问题的方式。

第一步是修复输入字段：

<input id="afield" type="text" placeholder="Name" name="afield">

我已更正了您的HTML语法，并将其称为字段afield

然后，您需要设置另一个名为notify_url的隐藏字段-这是PayPal付款后将把交易详细信息回传到的URL。

例如

<input type="hidden" name="notify_url" value="https://www.yourdomain.com/paypal.php">

然后在paypal.php内访问$_POST['afield']

在有帮助的情况下，paypal.php内您需要做些事情-这可验证从PayPal发回的交易明细是真实的，并且付款成功：

$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
  $keyval = explode ('=', $keyval);
  if (count($keyval) == 2)
    $myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
$req = 'cmd=_notify-validate';
if (function_exists('get_magic_quotes_gpc')) {
  $get_magic_quotes_exists = true;
}
foreach ($myPost as $key => $value) {
  if ($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) {
    $value = urlencode(stripslashes($value));
  } else {
    $value = urlencode($value);
  }
  $req .= "&$key=$value";
}

// Step 2: POST IPN data back to PayPal to validate
$ch = curl_init('https://ipnpb.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
if ( !($res = curl_exec($ch)) ) {
  curl_close($ch);
  exit;
}
curl_close($ch);

if (strcmp ($res, "VERIFIED") == 0 and $_POST['payment_status'] == 'Completed') {   

  // payment has been verified

}

您可以添加名称为 custom

的字段

唯一的问题是，即使在PDT中，贝宝也无法在答案中返回此字段

只能在IPN文本中看到此字段
