我正在尝试像这样将 POST vars 发送到 paypal ipn:
<form class="form-horizontal paypal-button" method="post" action="https://www.sandbox.paypal.com/cgi-bin/webscr" target="_top" style="opacity: 1;">
<input type="hidden" name="button" value="buynow">
<input type="hidden" name="business" value="vendedor@estadosbinarios.com">
<input type="hidden" name="quantity" value="1">
<input type="hidden" name="currency_code" value="EUR">
<input type="hidden" name="shipping" value="0">
<input type="hidden" name="tax" value="0">
<input type="hidden" name="notify_url" value="http://www.estadosbinarios.com/pagos/paypal_ipn.php">
<input type="hidden" name="return" value="http://www.estadosbinarios.com/pagos/success.php">
<input type="hidden" name="env" value="www.sandbox">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="bn" value="JavaScriptButton_buynow">
<!-- Enable override of buyers’s address stored with PayPal . -->
<input type="hidden" name="address_override" value="1">
<input id="nombre" name="first_name" type="text" placeholder="" class="form-control input-md">
<input id="nombre" name="last_name" type="text" placeholder="" class="form-control input-md">
</form>
但是 Paypal 不在乎我的变量 first_name 或 last_name,paypal 总是从 paypal 的用户帐户获取变量并覆盖该变量。
有什么方法可以选择我的变量吗?
