需要使用 laravel 控制器插入数组数据

Question

我有一个如下所示的数组数据。我想将其中的一些数据保存到 mysql 表中。 当我 dd($request->all) 控制器函数中的数据时，它看起来像这样。

array:1 [
  "{"cart":" => array:1 [
    "{"product":{"id":1,"category":1,"product_name":"Brinjal 500g","product_image":"1585409454.jpeg","product_price":232,"unit":"500g","product_description":null,"stock":"In Stock","product_status":1,"show":1,"delievery_date":null,"vendor":null,"quantity":18,"item_type":"feature_product","created_at":"2020-03-28T15:30:54.000000Z","updated_at":"2020-03-28T15:30:54.000000Z","deleted_at":null,"categories":{"id":1,"category_name":"Fresh Fruits","category_image":null,"category_description":null,"category_status":1,"show":0,"created_at":"2020-03-28T15:30:12.000000Z","updated_at":"2020-03-28T15:30:12.000000Z","deleted_at":null}},"quantity":1}" => null
  ]
]

我想将 id 和总数量显示最后一个对象添加到表中。表格行看起来像这样。

$table->increments('id');
$table->integer('order_id');
$table->integer('product_id')->unsigned();
$table->integer('total_quantity');
$table->timestamps();
$table->softDeletes();
$table->foreign('product_id')->references('id')->on('products')->onDelete('cascade');

如何在 laravel 中使用这些数据编写存储函数

结果数据如下所示

Array
(
    [{"cart":] => Array
        (
            [{"product":{"id":1,"category":1,"product_name":"Brinjal 500g","product_image":"1585409454.jpeg","product_price":232,"unit":"500g","product_description":null,"stock":"In Stock","product_status":1,"show":1,"delievery_date":null,"vendor":null,"quantity":18,"item_type":"feature_product","created_at":"2020-03-28T15:30:54.000000Z","updated_at":"2020-03-28T15:30:54.000000Z","deleted_at":null,"categories":{"id":1,"category_name":"Fresh Fruits","category_image":null,"category_description":null,"category_status":1,"show":0,"created_at":"2020-03-28T15:30:12.000000Z","updated_at":"2020-03-28T15:30:12.000000Z","deleted_at":null}},"quantity":1}] => 
        )

)

这是我的最新更新

$data = [];
foreach ($request->all() as $key => $value) {
   $data[$key]['product_id'] = $value['product']['id'];
   $data[$key]['quantity'] = $value['quantity'];
   dd($value);
}

Answer 1

遍历传入的数据并制作如下所示的数组。

通过创建数据数组并将数组作为批量数据插入数据库来试试这个：

// this will decode your json data that you're getting in the post data
$postdata = json_decode($request->all(), true);

$data = [];
foreach ($postdata as $key => $value) {        
    $data[$key]['product_id'] = $value['product']['id'];
    $data[$key]['quantity'] = $value['quantity'];
}

// $data now will have data as following structure

$data = [[
    'product_id' => 2,
    'total_quantity' => 7   

],
[
    'product_id' => 2,
    'total_quantity' => 7   

]];

$order = Order::create($data);
