Question

我正在使用Laravel 5.2进行项目。我有搜索和CSV导出功能。如果我单击CSV导出链接，我想将最新的搜索结果导出为CSV文件。

我的逻辑是：我将搜索结果传递到前端（index.blade.php），并将该值存储在一个隐藏的输入字段中，当我单击CSV导出链接时，我会将这个隐藏的输入传递给CSV导出控制器并执行打印操作。

我的问题是：如何更改这些数据格式（隐藏的输入数据）

到以下数据格式（Laravel查询格式）

Collection {#403 ▼
  #items: array:3 [▼
    0 => MemberMaster {#399 ▼
      #table: "memberMasternewdata"
      #primaryKey: "memberId"

      #perPage: 15
      +incrementing: true
      +timestamps: true
      #attributes: array:31 [▼
        "memberId" => 9
        "area_id" => 2
        "status_id" => 0
        "reference_id" => 0
        "productname" => null

    1 => MemberMaster {#400 ▶}
    2 => MemberMaster {#401 ▶}

提前谢谢！

Answer 1

您可以使用json_encode($collection)函数将您的Collection转换为json编码的字符串。

Answer 2

您需要“反序列化”。

您可以使用诸如https://jmsyst.com/libs/serializer之类的包，您可以将其提供json数据，并将其反序列化为所需的类。或..

首先，表单中的数据是JSON。您将需要通过调用

将其解码为对象或数组

json_decode($yourData);

解码后，您将拥有一个包含数据的对象。

您需要将其转换为对象，例如

$jsonObject = json_decode($jsonData);
$memberMaster = new MemberMaster();
$memberMaster->memberId = $jsonObject->memberId;

继续操作，直到构建了对象。

然后将其转换为集合，您可以调用Laravels集合助手

$memberMasterCollection = collect([$memberMaster]);

这显然可以达到最佳，但它为您提供了基础知识。

OR

您可以使其保持非常简单。而不是整个对象，而是通过ID传递给表单。

然后只需将您的ID发布到表单即可。

使用数据库调用从数据库中获取对象。
