我知道如何编码相关的选择字段，例如产品的颜色和尺寸，但不确定如何为 2 个不同的产品设置 2 个选择字段（下拉菜单）。我必须编写两个单独的表格吗？或者有没有办法将两者放在相同的形式中。在这里，我展示了后一个选项，但没有骰子。想法？

另外，试图弄清楚如何将空的第一个选项编码为“选择...”

有几种方法可以做到这一点，但考虑到最低限度的复杂性，我会将其编码为两种形式：

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">

   <input type="hidden" name="cmd" value="_cart"> 
   <input type="hidden" name="add" value="1">
   <input type="hidden" name="item_name" value="Annual Subscription"> 
   <input type="hidden" name="return" value="http://www.mycompany.com"> 
   <input type="hidden" name="cancel_return" value="http://www.mycompany.com"> 
   <input type="hidden" name="currency_code" value="USD">

   <p>U.S. Subscription</p> 
   <select name="os0">
