我试图设置一个按钮，为买家提供插入多个项目的选项，并迫使他们输入送货地址这里的代码：

<form action="<?php echo($paypal_url); ?>" method="post"> 
 <!-- Identify your business so that you can collect the payments. --> 
 <input type="hidden" name="business" value="<?php echo($paypal_email_address); ?>"> 

 <!-- Specify a Buy Now button. --> 
 <input type="hidden" name="cmd" value="_xclick"> 

 <!-- Specify details about the item that buyers will purchase. --> 
 <input type="hidden" name="item_name" value="<?php echo($item_name3); ?>"> 
 <input type="hidden" name="amount" value="<?php echo($item_price3); ?>">  
 <input type="hidden" name="currency_code" value="<?php echo($item_currency3); ?>"> 
 <input type="hidden" name="custom" value="<?php echo($mask); ?>">
 <input type="hidden" name="undefined_quantity" value="1">
 <input type="hidden" name="return" value="<?php echo($paypal_return); ?>">
 <input type="hidden" name="notify_url"value="http://www.mywebsite.co.uk/ipn2.php">
 <input type="hidden" name="cancel_return" value="<?php echo($cancel_return); ?>">
 <input type="hidden" name="no_note" value="1">
 <input type="hidden" name="no_shipping" value="2">

 <!-- Display the payment button. -->
 <input type="image" src="/img/PocketMask.png" border="0" name="submit" alt="PayPal - The safer, easier way to pay online." />

我在测试的过程中，它在沙盒和数量选项的工作很好，但似乎没有一个选项的送货地址，如果有人能帮助我，我真的很感激。
