paypal集成问题

Question

我无法弄清楚我的代码出错了什么,我得到了错误

"我们发现此购物车存在问题.如果问题仍然存在,请与商家联系."

这是我提交的表格......

<form name="paypalForm" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="business" value="example@example.com">
<input type="hidden" name="return" value="http://example.com/payment1.php">
<input type="hidden" name="undefined_quantity" value="0">
<input type="text" name="item_name1" value="1 item name">
<input type="text" name="item_number1" value="1">
<input type="text" name="amount1" value="0.4">
<input type="text" name="tax1" value="0.076">
<input type="text" name="item_name2" value="2 item name">
<input type="text" name="item_number2" value="2">
<input type="text" name="amount2" value="3.5">
<input type="text" name="tax2" value="0.665">
<input type="text" name="num_cart_items" value="2">
<input type="text" name="quantity" value="1">
<input type="text" name="currency_code" value="USD">
<input type="text" name="tax" value="0.741">
<input type="text" name="no_shipping" value="0">
<input type="text" name="no_note" value="0">
<input type="text" name="cancel_return" value="example.com/cancel.php">
<input type="text" name="notify_url" value="http://example.com/payment1.php">

</form>

我把类型"文本",所以我可以调试..

我看到了很多问题:

1. 您正在使用'undefined_quantity',它仅用于立即购买按钮.
2. 你试图做一个购物车上传按钮,但做错误的变量(你用'_x'枚举,而不只是'x'附加到var名称.我将在下面发布代码.
3. 您缺少必需的'_cart'按钮参数.购物车按钮总是有'add = 1'(添加到购物车),'display = 1'(查看购物车,覆盖添加)和'upload = 1'(上传,一次发送多个商品).
4. 您的取消返回网址没有PayPal所需的"http://".
5. PayPal只接受'浮点数'或两位小数精度的金额.
6. 与#5一起,我猜你的'税'值应该是百分比,而不是实际金额.为此,您将使用'tax_rate'作为百分比.如果您知道购物车中所有商品总额的确切税,请使用'tax_cart'.

请参阅下面的购物车上传按钮的按钮代码:

您应该在此处检查PayPal支持的网站付款标准(按钮)变量.
