如何获取 Paypal 返回的下拉菜单的值？

我想知道如何使用 Paypal 获取下拉菜单的值。

Paypal 方面一切正常，除了我不知道我的会员正在支付哪个订阅费用。

我的表格如下：

    <input type="hidden" name="on0" value="Formula">Formula
    <select name="os0">
        <option value="Basic">Basic €5</option>
        <option value="Standard">Standard €10</option>
        <option value="VIP">VIP €20</option>
    </select>

请问如何获取所选值？我猜是这样的：

$_POST['os0']

...但这行不通。请问我缺少什么？

非常感谢任何帮助，谢谢！

I'd like to know how to get the value of a dropdown menu with Paypal.

Everything works fine on Paypal's side, exept the fact that I don't know which subscription my members are paying for.

My form is as follow :

    <input type="hidden" name="on0" value="Formula">Formula
    <select name="os0">
        <option value="Basic">Basic €5</option>
        <option value="Standard">Standard €10</option>
        <option value="VIP">VIP €20</option>
    </select>

How can I grab the selected value please ? I guess it's something like :

$_POST['os0']

...But this doesn't work. What am i missing please ?

Any help much apreciated, thanks !

我不确定这是否是您的问题，但如果您不使用 HTTP POST，那么这些值将不会显示在 $_POST['os0'] 中。尝试使用 $_REQUEST['os0'] 来代替，看看是否可以通过这种方式获取值。

您可以在PHP 文档中阅读有关 $_POST 和 $_REQUEST 的更多信息。中了解如何设置表单提交方法：

<!-- Simple form which will send a POST request -->
<form action="" method="post">
  Name: <input type="text" name="name">
  <input type="submit" value="Save">
</form>

<!-- Form with fieldset, legend, and label -->
<form action="" method="post">
  <fieldset>
    <legend>Title</legend>
    <input type="radio" name="radio" id="radio"> <label for="radio">Click me</label>
  </fieldset>
</form>

您可以在Mozilla文档了解有关 HTTP GET 和 POST 一般来说，你可以阅读他们的W3C规范。

I'm not sure if this is your problem or not, but if you're not using HTTP POST, then the values won't show up in $_POST['os0']. Try using $_REQUEST['os0'] instead and see if you get the values that way.

You can read more about $_POST and $_REQUEST at the PHP docs. You can read about how to set the form submission method at the Mozilla docs:

<!-- Simple form which will send a POST request -->
<form action="" method="post">
  Name: <input type="text" name="name">
  <input type="submit" value="Save">
</form>

<!-- Form with fieldset, legend, and label -->
<form action="" method="post">
  <fieldset>
    <legend>Title</legend>
    <input type="radio" name="radio" id="radio"> <label for="radio">Click me</label>
  </fieldset>
</form>

To learn more about HTTP GET and POST in general, you can read their W3C specifications.
