javascript - 我如何通过 Paypal 提交多个产品复选框？

Question

我有基于查看购物车 方法的 Paypal 表格。 我转换了代码以收集多个复选框信息并通过 paypal 提交总和。 当我尝试通过单击“立即购买”来处理请求时，我从 paypal 收到一条错误消息:

You have requested an outdated version of PayPal. This error often results from the use of bookmarks.

代码如下:

<form target="_self" action="https://www.paypal.com/cgi-bin/webscr" method="post" id="submit" name="submit">
<!-- If using a Business or Company Logo Graphic, include the "cpp_header_image" variable in your View Cart code. -->
<input type="hidden" name="cpp_header_image" value="http://coreneto.com/picturish/assets/images/logo_light.png">
<p>
<input type="hidden" name="cmd" value="_submit">
<input type="hidden" name="display" value="1">

<!-- Replace value with the web page you want the customer to return to -->
<input type="hidden" name="shopping_url" value="http://www.yourwebsite.com/Script_02.html">
</p>
</form>
<!-- End of the viewcart FORM -->

<!-- Start of Form -->
<!-- Note: target="paypal" was replaced with the variable target="_self" -->
<!-- Note: shopping_url also added to code -->
<!-- These two changes allow better functionality with IE and Firefox -->
