Question

我在Paypal沙箱上创建了买家和卖家测试帐户。我还创建了一个Paypal按钮。

Paypal按钮：

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
  <input type="hidden" name="cmd" value="_s-xclick">
  <input type="hidden" name="hosted_button_id" value="6M75NVDV8ZHR8">
  <input type="image" src="https://www.sandbox.paypal.com/en_US/i/btn/btn_buynowCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
  <img alt="" border="0" src="https://www.sandbox.paypal.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>

我启用了IPN并在那里设置了通知网址在创建Paypal按钮时，我为成功的交易插入了我的网站URL 成功的交易和IPN通知共享相同的网址。

以下是引用网址的PHP脚本：

<?php  
  // read the post from PayPal system and add 'cmd'  
  $req = 'cmd=_notify-validate';  
  print_r($_POST);

  foreach ($_POST as $key => $value) {  
    echo "loop";
    echo $value = urlencode(stripslashes($value));  
    echo $req .= "&$key=$value";  
  }

  // 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 (strcmp ($res, "VERIFIED") == 0) {  
        echo " PAYMENT VALIDATED & VERIFIED! "; 
      }
      else if (strcmp ($res, "INVALID") == 0) {
        echo " PAYMENT INVALID & INVESTIGATE MANUALY!  ";
      }  
    }  
    fclose ($fp);  
  }
?>

print_r函数仅打印Array()，在foreach循环中不显示任何内容。

页面上只显示PAYMENT INVALID & INVESTIGATE MANUALLY!。

这里有什么问题？
因为我想在成功的交易中插入一些数据。

这是我的帖子数组：

    [L_SEVERITYCODE3] => Error
)

我更改了ipn.php代码，现在我收到此错误：“信用卡号无效”。

我已使用预配置创建了买方帐户，并随机生成信用卡号。

现在，当我去添加/编辑信用卡时，我无法仅在地址和有效期内编辑卡号。

并且也无法添加新的信用卡，而是将此信用卡的错误分配给另一个Paypal帐户消息。

print_r将其输出回显给paypal的脚本。您可能希望将其记录到文件中，以便稍后查看

为什么Paypal交易详情数组被返回为空？
