在PayPal表单中添加自定义隐藏字段，并在重定向页面上获取

问题描述：

我想在成功的PayPal过程（重定向页面）后立即获取用户信息（电子邮件）和贝宝账单信息（定价，数量），然后插入到mysql表。在PayPal表单中添加自定义隐藏字段，并在重定向页面上获取

我也是现在购买按钮使用<input type="hidden" name="notify_url">并设置它的值，例如：

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" id="lf2"> 
<input type="hidden" name="cmd" value="_s-xclick"> 
<input type="hidden" name="hosted_button_id" value="xxxxx"> 
<input type="hidden" name="custom"> 
<input type="hidden" name="notify_url"> 
<input type="image" src="https://www.paypalobjects.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.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1"> 
</form> 

$notify_url='http://mysite.com/ipn/index.php?order_sld=123'; 

<script language="javascript"> 
document.getElementsByName('custom').value='123'; 
document.getElementsByName('notify_url').value='<?=$notify_url?>'; 

document.forms['lf2'].submit(); 
</script>

和我的IPN/index.php的脚本是：

function FetchOrder() 
    { 
    $array = array(); 

    $array['transactionID']=$_POST["txn_id"]; 
    $array['item']=$_POST["item_name"]; 
    $array['amount']=$_POST["mc_gross"]; 
    $array['currency']=$_POST["mc_currency"]; 
    $datefields=explode(" ",$_POST["payment_date"]); 
    $array['time']=$datefields[0]; 
    $array['date']=str_replace(",","",$datefields[2])." ".$datefields[1]." ".$datefields[3]; 
    $array['timestamp']=strtotime($array['date']." ".$array['time']); 
    $array['status']=$_POST["payment_status"]; 
    $array['firstname']=$_POST["first_name"]; 
    $array['lastname']=$_POST["last_name"]; 
    $array['email']=$_POST["payer_email"]; 
    $array['custom']=$_POST["option_selection1"]; 
    $array['sld']=$_POST["notify_url"]; 

    if ($array['transactionID'] AND $array['amount']) { 
     return send_email($array); 
    } else { 
     return 0; 
    } 
} 

/** 
* Send email 
*/ 
function send_email($array) 
    { 
    $to = "[email protected]"; 
    $email = "[email protected]"; 
    $name = "Sajid"; 

    $subject = "Testing Paypal IPN"; 

    $msg = "<table> 
      <tr><td>Transaction ID: </td><td>".$array['transactionID']."</td></tr> 
      <tr><td>Item: </td><td>".$array['item']."</td></tr> 
      <tr><td>Amount: </td><td>".$array['amount']."</td></tr> 
      <tr><td>Currency: </td><td>".$array['currency']."</td></tr> 
      <tr><td>Time: </td><td>".$array['time']."</td></tr> 
      <tr><td>Date: </td><td>".$array['date']."</td></tr> 
      <tr><td>Timestamp: </td><td>".$array['timestamp']."</td></tr> 
      <tr><td>Status: </td><td>".$array['status']."</td></tr> 
      <tr><td>First Name: </td><td>".$array['firstname']."</td></tr> 
      <tr><td>Last Name: </td><td>".$array['lastname']."</td></tr> 
      <tr><td>Email: </td><td>".$array['email']."</td></tr> 
      <tr><td>Custom: </td><td>".$array['custom']."</td></tr> 
      <tr><td>SLD: </td><td>".$array['sld']."</td></tr> 
      </table>"; 

    // To send HTML mail, the Content-type header must be set 
    $headers = 'MIME-Version: 1.0' . "\r\n"; 
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; 

    // Additional headers 
    $headers .= "From: $name <$email>" . "\r\n"; 
    // Mail it to client. 
    mail($to, $subject, $msg, $headers); 
    return 1; 
} 
FetchOrder();

但邮件仅包含：

Transaction ID:  6BD19776WW7238524 
Item: 
Amount:  12.00 
Currency: USD 
Time: 04:04:21 
Date: 05 Jan 2012 
Timestamp: 1325761461 
Status:  Completed 
First Name:  ABC 
Last Name: XYZ 
Email: [email protected] 
Custom:  
SLD:
