Paypal IPN变量PHP

嗨，我正在努力建立ipn，但我对php非常陌生，我以为我已经弄明白了，但还没有接近：）

不管怎么说，我想做的就是在付款后，在一个文本文件中写下人的名字，然后在旁边的文本字段中写下他们的输入，我在我的按钮中做了这样的输入

<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">

我已经弄明白了，我花了一整天的时间（在凌晨3:40开始工作），但是一天之内就学会了很多php哈，我会在几分钟后发布我所做的事情。你为什么要检查神奇的引用？此选项已被弃用，任何人都不应使用它。这给你的代码增加了额外的复杂性。我刚刚从paypal复制并粘贴了这个例子。我真的不太懂php，这就是为什么我遇到麻烦的原因。我的php知识的扩展是写一个文本文件：）更新了我的问题，希望这更简单。我所要做的就是在他们付钱后写下他们的名字和输入的内容我的服务器上的txt文件中的一行文本字段。好吧，我的ipn现在成功了，但是当我使用上面的脚本实际运行它时，它不会发送电子邮件或写入确实存在的文本文件。有什么想法吗？我想我很接近了，我只是没有看到它正常工作，在我的高级变量中，我有notify_url=，我也检查过它，它存在，但它不工作？你能告诉我们你是如何解决这个问题的吗？目前，这个答案并不能真正帮助其他可能有同样问题的人。如果你这么做了，我就打开你的问题。谢谢。对不起，这是一个老问题，当我是真正的新代码和网站，但是的，我记得下面的教程，并能够得到它连接和工作。主要的一点是在贝宝的网站上，你需要指向ipn脚本的按钮
