Paypal IPN 变量 PHP [关闭]

Question

您好，我正在设置 ipn，但我对 php 非常陌生，我以为我已经弄清楚但还没有接近 :)

无论如何，我要做的就是在付款后将人名写入文本文件，然后在旁边将他们的输入写入我在按钮中创建的文本字段中，如下所示

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="5ES3TSKJNLJ24">
<table style="text-align: right; width: 100%;">
<tr><td><input type="hidden" name="on0" value="Amount you'd like to donate">Amount you'd like to donate</td></tr><tr><td><select name="os0">
    <option value="Just the license">Just the license $2.99 USD</option>
    <option value="A bit more">A bit more $5.99 USD</option>
    <option value="Two bits more">Two bits more $8.99 USD</option>
    <option value="A lot more">A lot more $15.00 USD</option>
    <option value="We love you :)">We love you :) $50.00 USD</option>
</select> </td></tr>
<tr><td><input type="hidden" name="on1" value="Primary Phone Gmail">Primary Phone Gmail</td></tr><tr><td><input type="text" name="os1" maxlength="200"></td></tr>
</table>
<input type="hidden" name="currency_code" value="USD">
<input type="image" align="right" 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!">

</form>

我的 ipn.php 是这样的

<?php
// Revision Notes
// 11/04/11 - changed post back url from https://www.paypal.com/cgi-bin/webscr to https://ipnpb.paypal.com/cgi-bin/webscr
// For more info see below:
// https://www.x.com/content/bulletin-ip-address-expansion-paypal-services
// "ACTION REQUIRED: if you are using IPN (Instant Payment Notification) for Order Management and your IPN listener script is behind a firewall that uses ACL (Access Control List) rules which restrict outbound traffic to a limited number of IP addresses, then you may need to do one of the following: 
// To continue posting back to https://www.paypal.com  to perform IPN validation you will need to update your firewall ACL to allow outbound access to *any* IP address for the servers that host your IPN script
// OR Alternatively, you will need to modify  your IPN script to post back IPNs to the newly created URL https://ipnpb.paypal.com using HTTPS (port 443) and update firewall ACL rules to allow outbound access to the ipnpb.paypal.com IP ranges (see end of message)."


// read the post from PayPal system and add 'cmd'

已经想通了，运行起来花了我一整天（凌晨 3:40 开始工作），但确实在一天内学习了很多 php，哈哈，我会在几篇文章中发布我所做的
