Laravel如何使用$请求，除了嵌套数组

Question

是否可以在嵌套数组上使用 $ request-＆gt;除外？这是请求数据：

    [▼
      "id" => 1
      "products" => array:1 [▼
        0 => array:4 [▼
          "id" => 1
          "name" => "sample product"
          "date" => "07/04/2022"
          "frequency" => array:1 [ …1]
        ]
      ]
    ]

我的目标是删除一些钥匙值对，例如删除 id ， date 和频率。我所需的结果是：

    [▼
      "id" => 1
      "products" => array:1 [▼
        0 => array:1 [▼
          "name" => "sample product"
        ]
      ]
    ]

到目前为止，我尝试的是使用 arr：除函数外：

$request->products = Arr::except($request->products['0'], ['id', 'date', 'frequency']);

但这应该应用于所有项目。假设我有两个项目产品，所需的结果是：

        [▼
          "id" => 1
          "products" => array:2 [▼
            0 => array:1 [▼
              "name" => "sample product"
            ]
            1 => array:1 [▼
              "name" => "sample product 2"
            ]
          ]
        ]

需要您对最佳方法的投入。谢谢你！

除非我缺少明显的东西，否则您能否不仅在$ replect olection对象中迭代products？

$filtered = [];

foreach ($request->products as $product) {
    $filtered[] = Arr::except($product, ['id', 'date', 'frequency']);
}

dd($filtered);

导致$过滤包含：

^ array:2 [▼
  "id" => 1
  "products" => array:2 [▼
    0 => array:1 [▼
      "name" => "sample product"
    ]
    1 => array:1 [▼
      "name" => "sample product 2"
    ]
  ]
]

我可以看到$请求除了仅在顶级上工作

而不确定您的意思是上述原则对我有用。

$filtered = [];
foreach ($request->products as $product) {
    $filtered[] = Arr::except($product, ['id', 'date', 'frequency']);
}
$request->merge(['products' => $filtered]);

如果我提供以下内容：

{
    "id": 1,
    "products": [
        {
            "id": 1,
            "name": "sample product",
            "date": "07/04/2022",
            "frequency": []
        },
        {
            "id": 2,
            "name": "sample product 2",
            "date": "07/04/2022",
            "frequency": []
        }
    ]
}

然后进行dd（$ request-＆gt; products）;我得到：

^ array:2 [▼
  0 => array:1 [▼
    "name" => "sample product"
  ]
  1 => array:1 [▼
    "name" => "sample product 2"
  ]
]
