通过PayPal支付多个项目（一次） [英] Paying for multiple items (at once) via paypal
问题描述
我有一个产品列表，我想添加一个现在付款按钮，这样我就可以让我的客户通过Paypal付款。
I have a list of products that I'd like to add a "pay now" button to so that I can allow my customers to pay via Paypal.
我已经通过了文档，并找不到如何做到这一点。
我可以添加多个项目，但这不会很方便，因为我已经有要处理的项目列表。
我还需要结账程序来逐项列出订单，所以1价格的立即购买也是不错的选择。
I've gone through the documentation and can't find how to do this. I can add multiple items, but this is not going to be handy as I already have the list of items to process. I also need the checkout process to itemize the order, so a "buy now" with 1 price is no good either.
尝试过（没有运气）：
<form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="business" value="email@domain.com">
<input type="hidden" name="lc" value="GB">
<input type="hidden" name="item_name" value="test 1">
<input type="hidden" name="item_number" value="1">
<input type="hidden" name="item_name2" value="test 2">
<input type="hidden" name="item_number2" value="2">
<input type="hidden" name="item_name3" value="test 3">
<input type="hidden" name="item_number3" value="3">
<input type="hidden" name="amount" value="99.00">
<input type="hidden" name="currency_code" value="GBP">
<input type="hidden" name="button_subtype" value="products">
<input type="hidden" name="no_note" value="0">
<input type="hidden" name="add" value="1">

推荐答案
查看本示例并相应地对其进行更改。基本上在数字前添加下划线到项目名称，并给出唯一的名称，金额也使用下划线和数字。
See this sample and make the changes to yours accordingly. Basically add underscore to item name before number and give unique name to amount also with underscore and number.
您必须根据购物车总数为每件商品添加金额。 / p>
You have to give amount to each item based on your carts totals.
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="upload" value="1">
<input type="hidden" name="business" value="youremail@mail.com">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="item_name_1" value="beach ball">
<input type="hidden" name="amount_1" value="15">
<input type="hidden" name="item_name_2" value="towel">
<input type="hidden" name="amount_2" value="20">
<input type="image" src="http://www.paypal.com/en_US/i/btn/x-click-but01.gif" name="submit" alt="Make payments with PayPal - it's fast, free and secure!">
</form>
指定数量（可选）
Specify Quantity(optional)
<input type="hidden" name="quantity_1" value="1">
