Question

嗨，我正在尝试实现一个用于下订单的API。我想使用laarvel验证来验证数据。以下是我想要验证的示例输入值

  {
  "phone": "phone",
  "cart_items": [
    {
      "category_id": "1",
      "product_id": "1",
      "product_count": "1",
      "quantity": "1",
      "prize_per_unit": "1"
    },
    {
      "category_id": "2",
      "product_id": "1",
      "product_count": "1",
      "quantity": "1",
      "prize_per_unit": "1"
    }
  ],
  "total": "2",
  "net_amount": "100"
}

我要根据产品ID和类别ID根据产品表验证产品ID。产品表包含product_id和类别ID，以下是我的验证规则。

$validator=Validator::make($request->all(),[
            //'customer_id'=>['required','exists:users,id'],
            'phone'=>['required','max:12',function($attribute, $value, $fail) {

                $re = '/^(?:(?:\+|0{0,2})91(\s*[\-]\s*)?|[0]?)?[6789]\d{9}$/';

                if (preg_match_all($re, $value, $matches)) {
                    return true;
                }
                return $fail($attribute.' is invalid.');


            } ],

            'cart_items.*.category_id'=>['required','exists:categories,cat_id'],
            'cart_items.*.product_id'=>['required',Rule::exists('products','product_id')->where(function($query)use ($request) {
                $query->where('category_cat_id',$request->category_id);

            })],
            'cart_items.*.product_count'=>['required','integer','max:100','min:1',''],
            'cart_items.*.quantity'=>['required','integer'],
            'cart_items.*.delivery_charge'=>['nullable','integer','min:0'],
            'cart_items.*.prize_per_unit'=>['required','integer','min:1'],
            'total'=>['required','integer','min:1'],
            'net_amount'=>['required','integer','min:1'],



        ],[
            'category_id.exists'=>'Not a valid category',
            'product_id.exists'=>'Not a valid product'

        ]);

我的问题是如何验证此规则

'cart_items.*.product_id'=>['required',Rule::exists('products','product_id')->where(function($query)use ($request) 
        {
                $query->where('category_cat_id',$request->category_id);
                })],

将替换为数组的$request->category_id

Laravel验证存在验证中的数组
