经过多年的努力，我终于设法从Paypal工作中获得了我的IPN。我在GITHUB上找到了一个代码，它提供了一个ipn.log，它返回“Verified”或“Invalid”。
使用Paypal Sandbox后，交易正常，我的ipn.log文件更新告诉我它已经过验证。
然而，我在此之后输入的代码不起作用，我完全不知道如何修复它！
请参阅购买页面上使用的表格.. credit.php
<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="custom" value="<?=$person?>">
<input type="hidden" name="business" value="mypaypal@email.com">
<input type="hidden" name="item_name" value="5000 Credits for <?=$person?>">
<input type="hidden" name="item_number" value="5000 Credits">
<input type="hidden" name="amount" value="5.00">
<input type="hidden" name="no_shipping" value="1">
<input type="hidden" name="no_note" value="0">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="return" value="<?=$site[location]?>creditsdone.php">
<input type="hidden" name="cancel_return" value="<?=$site[location]?>">
<input src="images/buy_button.gif" height="22" type="image" width="156" name="submit" alt="Make payments with PayPal">
</form>
$ person是从我的数据库中获取的用户名。
请参阅我的ipn.php页面。由于这是有效的，我已经将IPN验证系统涂黑了。

我完全失去了，我的思绪是一个尴尬！请理解我的php编码级别非常基础！
感谢您的帮助！
答案 0 :(得分：1)
您正在使用变量$mc_gross，但您没有从$_POST数据中获取该数据，我不知道您应该如何获得实际金额？
如果你做$ mc_gross = $_POST['mc_gross'];，你实际上已经找到了你想要的价格！
