Laravel中无法进行多图像验证

Question

我只是添加添加更多图像，当用户单击添加更多按钮时，我将添加输入及其字段名称，例如照片[]

当我仅使用照片时，我正在使用Ajax来添加数据，

<div class="col-md-6">
    <div class="form-group">
      <label class="f-14 f-w-700">Product Photo</label>
      <input type="file" class="form-control" name="photo[]">
      <small class="text-danger f-w-700 photo-error-label"></small>
    </div>
</div>

$validate = Validator::make($request->all(),[
            'category_id'=>'required',
            'sub_category_id'=>'required',
            'product_id'=>'required',
            'name'=>'required',
            'keyword'=>'required',
            'description'=>'required',
            'specification'=>'required',
            'model_no'=>'required',
            'document'=>'required',
            'photo.*'=>'required',
            'video.*'=>'required',
        ],[
            'category_id.required'=>'The category field is required.',
            'sub_category_id.required'=>'The sub category field is required.',
            'product_id.required'=>'The product field is required.'
        ]);

        /* if fail validation then return error in json with status code */
        if($validate->fails()){
            return response()->json(["errors"=>$validate->errors()],422);
        }
