【问题描述】：

我正在尝试遍历一个多维数组，以获取属于订单项的产品的属性。它们看起来基本上是这样的：（我做了一个 json_encode 以便更容易阅读）

[{
    "rcpt": "email@email.com",
    "vars": [{
        "name": "SYSTEM",
        "content": "Bikes"
    }, {
        "name": "CUSTOMERSERVICE",
        "content": "(855-553-4889)"
    }, {
        "name": "IMAGE",

    }, {

    }, {

        "content": "Bikes"
    }, {

        "content": "Bikes"
    }, {

    }, {
        "name": "lastName",
        "content": "tethuhhu"
    }, {
        "name": "address",
        "content": "295 Place St"
    }, {
        "name": "city",

    }, {
        "name": "zip",
        "content": "11238"
    }, {
        "name": "country",
        "content": "US"
    }, {
        "name": "phone",
        "content": "8888888888"
    }, {

    }, {
        "name": "shipToLastName",
        "content": "tethuhhu"
    }, {
        "name": "shipToAaddress",
        "content": "295 Place St"
    }, {
        "name": "shipToCity",
        "content": "Brooklyn"
    }, {
        "name": "shipToState",
        "content": "NY"
    }, {
        "name": "shipToZipCode",
        "content": "11238"
    }, {
        "name": "ShipToCountry",
        "content": "US"
    }, {
        "name": "ShipToCountry",
        "content": "US"
    }]
}]

所以我试图打印出每张礼券的类型和兑换号码。当我像这样遍历 {{ giftCertificates }} 时：

{{#each giftCertificates}}
    {{type}} {{redemptionNumber}}
{{/each}}

我得到了其中一个订单项，但没有得到另一个。我猜也许当它再次循环时它被覆盖了？但我也尝试遍历 {{ item }} 并抓取 {{ giftCertificates.type }} 和 {{ giftCertificates.redemptionNumber }} ，但这也不起作用。从每个订单项中获取所有这些的正确方法是什么？

感谢您的帮助。

【解决方案1】：

我知道这是一个非常古老的问题，但是：

您可以使用{{this.proprietyName}}获取类型和编号：

{{#each giftCertificates}}
   {{this.892.type}}
{{/each}}

别忘了把这个添加到山魈messageo

"merge": true,
"merge_language": "handlebars",

另外，数据结构也不理想：

giftCertificates[
    {
     "id": "892",
     "redemptionNumber": "xxxxxx",
     "type": "Annual"
    }, 
    {
     "id": "893",
     "redemptionNumber": "xxxxxx",
     "type": "Annual"
    }
]

会更容易处理。
