我已经联系了贝宝的人。他们说这是一个背景问题。我可以知道上面代码中的错误是什么吗？请帮我解决这个问题好吗？

Answer 1

您必须在html表单中使用参数"p3"one_answers"t3"

p3：为使用t3指定的持续时间单位指定一个允许范围内的整数值。

t3：定期订阅持续时间单位。

允许值为：
D–天；p3的允许范围为1至90
W，持续数周；p3的允许范围为1至52
M，持续数月；p3的允许范围为1到24
Y–年；p3的允许范围为1到5

此外，cmd参数必须是_xclick-subscriptions，而不是_cart

遵循此示例：

<form method="post" name="formName" id="submitThisForm" action="https://www.paypal.com/cgi-bin/webscr" >
<input type="hidden" name="cmd" value="_xclick-subscriptions">
<input type="hidden" name="business" value="[e-mail]" />
<input type="hidden" name="item_name" value="Your Membership" />
<input type="hidden" name="a3" value="0.01">
<input type="hidden" name="p3" value="1"> 
<input type="hidden" name="t3" value="M">
<input type="hidden" name="src" value="1">
<input type="hidden" name="sra" value="1">
<input type="hidden" name="item_number" value="2" />
<input type="hidden" name="custom" value="SECURITYCODE" />
<input type="hidden" name="currency_code" value="USD" />
<input type="hidden" name="quantity" value="1" />
<input type="hidden" name="no_shipping" value="1" />
<input type="hidden" name="return" value="page going after payment" />
<input type="hidden" name="cancel_return" value="" />
<input type="hidden" name="cbt" value="ITEM DESCRIPTION" />
<input type="hidden" name="rm" value="2" />
<input type="hidden" name="notify_url" value="your_listener_file.php" />

参数"p3"的允许范围为1到24。

在您的情况下必须设置

<input type="hidden" name="p3" value="1">

与

<input type="hidden" name="t3" value="M">

Answer 2

您似乎没有创建订阅按钮，因为缺少值="_s-xclick"。对于订阅按钮，您可以在按钮代码中指定以下变量；

<input type="hidden" name="cmd" value="_s-xclick">
