如何在我的自定义模块中拦截$ _POST数据（从一个模块打印出来）？Drupal 7 Commerce Paypal IPN
我正在使用Commerce模块和PayPal在我的Drupal网站上提供付款。
我的问题是围绕我无法收到PayPal IPN交易数据。
在Drupal日志中，我找到了Commerce_checkout模块生成的$ _POST数据。该数据如下：
Array
(
[mc_gross] => 1.00
[invoice] => 42-1466371657
[protection_eligibility] => Ineligible
[item_number1] =>
[payer_id] => 69AYKSJVPCN48
[tax] => 0.00
[payment_date] => 14:27:58 Jun 19, 2016 PDT
[option_selection1_1] => 1
[payment_status] => Completed
[charset] => utf-8
[mc_shipping] => 0.00
[mc_handling] => 0.00
[first_name] => test
[mc_fee] => 0.24
[notify_version] => 3.8
[custom] =>
[payer_status] => verified
[business] => [email protected]
[num_cart_items] => 1
[mc_handling1] => 0.00
[payer_email] => [email protected]
[verify_sign] => AFcWxV21C7fd0v3bYYYRCpSSRl31AfxmnZuHUiYodjVMGelbrZ3s3Ylv
[mc_shipping1] => 0.00
[tax1] => 0.00
[option_name1_1] => Product count
[txn_id] => 10L50068V5914254J
[payment_type] => instant
[last_name] => buyer
[item_name1] => Order 42 at Mysite
[receiver_email] => [email protected]
[payment_fee] =>
[quantity1] => 1
[receiver_id] => BGEFKZZCD22XA
[txn_type] => cart
[mc_gross_1] => 1.00
[mc_currency] => GBP
[residence_country] => GB
[test_ipn] => 1
[transaction_subject] =>
[payment_gross] =>
[auth] => AT2Z0IOHTJopgBP2XkLyQCQ8L2lhYfZUxhpmutbdOyy-ZqV7HolIN2nSv2Tl4shPAi77wEUvDTmNKAfewbCZ83Q
)
即输出从下面的代码：
function commerce_paypal_wps_redirect_form_validate($order, $payment_method) {
if (!empty($payment_method['settings']['ipn_logging']) &&
$payment_method['settings']['ipn_logging'] == 'full_ipn') {
watchdog('commerce_paypal_wps', 'Customer returned from PayPal with the following POST data:!ipn_data', array('!ipn_data' => '<pre>' . check_plain(print_r($_POST, TRUE)) . '</pre>'), WATCHDOG_NOTICE);
}
我的问题是，我需要访问相同的数据，但是从一个自定义模块。
我实现hook_redirect_form，在我试图挖掘并访问$ _ POST数据hook_form_validate但都没有成功。
任何人都可以用正确的方法指导我解决这个难题吗？
