Paypal 可变/动态价格的“立即购买”按钮

Question

这不是这篇文章的重复内容。

引用上述文章：

“截至2017年6月29日，我发现此方法不再奏效。Paypal再次修改了其规定，我认为它不再接受表单提交中的隐藏HTML字段：必须在Paypal的按钮编辑器中设置。”

Paypal文档一团糟。一半的链接是失效的，另一半的链接指向文档索引。

有没有聪明人知道如何实现一个Paypal支付按钮，可以动态设置价格？

PayPal推荐使用快速结账客户端集成，并且您可以从您的网站动态地将金额发送到PayPal代码。

请参考以下链接以了解PayPal快速结账客户端集成：

https://developer.paypal.com/docs/integration/direct/express-checkout/integration-jsv4/client-side-REST-integration/

https://developer.paypal.com/demo/checkout/#/pattern/client

否则，请尝试以下 PayPal HTML 按钮代码。

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
  <!-- Identify your business so that you can collect the payments. -->
  <input type="hidden" name="business" value="[e-mail]"> <!-- Add your PayPal Seller/Business email address Required-->
  <!-- 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=""> <!-- Add Description e.g your room type Required-->
  <input type="hidden" name="amount" value=""> <!-- Dynamically add Total Amount Required-->
  <input type="hidden" name="currency_code" value=""> <!-- Update to your currency -->
  <input id="invoice" type="hidden" value="" name="invoice"> <!-- Add Unique invoice for each transaction -->
  <input type="hidden" name="notify_url" value="www.yourwebsite.com/ipn.php"> <!-- Please add IPN URL You can use this service to automate back-office and administrative functions, including fulfilling orders, tracking customers, and providing status and other information related to transactions. -->
  <input type='hidden' name='cancel_return' value='' /> <!-- Take customers to this URL when they cancel their checkout -->
  <input type='hidden' name='return' value='' /> <!-- Take customers to this URL when they finish their checkout  -->
  <!-- Display the payment button. -->

</form>

<form name="_xclick"  method="post" action= "https://www.paypal.com/cgi-bin/webscr">
  <input type="hidden" name="cmd" value="_xclick">
  <input type="hidden" name="business" value="[e-mail]">
  <input type="hidden" name="item_name" value="XXXX">
  <input type="hidden" name="notify_url" value="http://XXXXXXX.com/ipn.php" />
  <input type="hidden" id="buybuttonid" name="custom" value="XXXXX" />
  <input type="hidden" name="amount" value="amount that you want to send">
  <input type="submit" value="Buy Now">
</form>

请使用此按钮，不要传递物品编号和数量，否则它将无法动态设置金额。

只需创建简单的立即购买按钮，并在创建按钮时将价格/金额值留空。
