Laravel 添加额外数据到数组

Question

我的数据如下：

data: [,…]

    0: {name: "Product One", price: "15000", quantity: 2, attributes: {attr: {name: "weight", value: "35"}},…}

        attributes: {attr: {name: "weight", value: "35"}}

        conditions: [{name: "blue", value: 0}, {name: "L", value: 0}]

        name: "Product One"

        price: "15000"

        quantity: 2

我需要添加id到每个数据数组中，例如：

data: [,…]

    0: {name: "Product One", price: "15000", quantity: 2, attributes: {attr: {name: "weight", value: "35"}},…}

        attributes: {attr: {name: "weight", value: "35"}}

        conditions: [{name: "blue", value: 0}, {name: "L", value: 0}]

        name: "Product One"

        price: "15000"

        quantity: 2

        id: 10 // added id

我的数据库如下所示：

代码

目前刚刚获得我的专栏，还cart_data需要添加专栏。id

$items2 = CartStorage::where('user_id', $user->id)->get();

$items = [];

foreach($items2 as $item){

  $items[] = json_decode($item['cart_data']); 

}

Answer 1

可以通过创建一个 var 并将其添加到那里，如下所示：$items2 = CartStorage::where('user_id', $user->id)->get();$items = [];foreach($items2 as $item){  $decodedItems       = json_decode($item['cart_data'], true);  $decodedItems['id'] = $item['id'];  $items[]            = $decodedItems;}
