Question

我被困了好几天了！我试图通过并行付款从PayPal IPN获取详细信息。

我需要发送资金的两个电子邮件地址和金额，以及状态。

我在这里看：

https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_APIPN

这些是我的代码中的行，我尝试获取电子邮件和金额：

$Email1 = $_POST['transaction[0].receiver'];
$Email2 = $_POST['transaction[1].receiver'];

数量部分：

$Amount1 = $_POST['transaction[0].amount'];
$Amount2 =  $_POST['transaction[1].amount'];

我使用此页面的IPN代码。

https://cms.paypal.com/cms_content/AU/en_AU/files/developer/IPN_PHP_41.txt

有任何帮助吗？ POST变量是空白的吗？

更新：我找到了这个：

$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$_YOUR_POST = array();
foreach ($raw_post_array as $keyval) {

  if (count($keyval) == 2)
    $_YOUR_POST[$keyval[0]] = urldecode($keyval[1]);

在日志文件中生成此内容：

[10-Dec-2011 07:13:50] transaction[0].id_for_sender_txn = xxxxx
[10-Dec-2011 07:13:50] log_default_shipping_address_in_transaction = xxx
[10-Dec-2011 07:13:50] transaction[0].receiver = xxxxx
[10-Dec-2011 07:13:50] action_type = xxxx

[10-Dec-2011 07:13:50] transaction[1].paymentType = xxx
[10-Dec-2011 07:13:50] transaction[0].amount = xxxx
[10-Dec-2011 07:13:50] charset = xxx

有谁能告诉我如何将这些变成变量，因为这是打印在日志文件中的内容？

Answer 1

尝试$_POST['transaction']['0']['receiver']，依此类推。此外，启用E_ALL错误消息，以便您看到有关此类内容的通知。如果已启用，并且您检查了错误日志，则会看到未定义的索引通知。此外，如果您迫切需要调试$_POST/$_GET/whatever内容并且不是您控制请求，则可以始终将内容写入文件并进行检查。
