我正在使用PayPal rest-api-sdk-php最新版本.在创建付款和执行付款以及获取所有相关数据方面,一切都运行良好,但已决定我希望通过paypal支付的总金额.它返回一个JSON对象,例如下面的例子

"transactions": [
    {
        "amount": {
            "total": "20.00",
            "currency": "GBP",
            "details": {
                "subtotal": "17.50",
                "tax": "1.30",
                "shipping": "1.20"
            }
        },
        "description": "Payment description",
        "invoice_number": "55e30dbd55cea",
        "item_list": {
            "items": [
                {
                    "name": "Ground Coffee 40 oz",
                    "price": "7.50",
                    "currency": "GBP",
                    "quantity": "1",
                    "description": "Ground Coffee 40 oz",
                    "tax": "0.30"
                },
                {
                    "name": "Granola bars",
                    "price": "2.00",
                    "currency": "USD",
                    "quantity": "5",
                    "description": "Granola Bars with Peanuts",
                    "tax": "0.20"
                }
            ]
        },
    }
],

我试过调用$ payment-> transactions-> amount-> total但是得到了一个错误.只是想知道是否有人可以解决问题.谢谢

我有一个像这样的html页面设置

<div class="row row-venue">
    <div class="col-sm-12">
        <h3>Venue 1</h3>
    </div>
</div>
<div class="row row-venue">
    <div class="col-sm-12">
        <h3>Venue 2</h3>
    </div>
</div>

我想要做的就是让每个奇数的h3与每个偶数颜色不同.我试过下面的代码

div.row-venue div.col-venue h3:nth-of-type(odd){
  color:white;
}
div.row-venue div.col-venue h3:nth-of-type(even){
  color:black;
}

甚至只是尝试过

h3:nth-of-type(odd){
  color:white;
}

h3:nth-of-type(even){
  color:black;
}

我似乎无法理解它,任何帮助将不胜感激
