Form Data Binding (multipart file)

[ironytr]

Hello, i have a basic project to learn golang.
Below sample works with JSON binding perfectly. As frontend im using inertia-js, when im uploading a file request casting to form-data. but form-data binding is not working like json. and i couldnt find a solution on net with echo. in laravel binding request nested objects like

        'category_description.*.name'=>'required|min:3|max:50',
            'category_description.*.description'=>'min:3|max:50',
            'category_description.*.meta_name'=>'required|min:3|max:50',
            'category_description.*.meta_description'=>'min:3|max:50',
            'category_description.*.meta_keywords'=>'required|min:3|max:50'`

how can i achieve json like binding with form-data and plus []file binding? is there a way? thank you for your help and sorry for my english (self learning programming and english)

type ProductUpdateRequest struct {
	ID   uint  `json:"id" form:"id" query:"id" validate:"required"`
	Name string `json:"name" form:"name" query:"name" validate:"required"`
	Description string `json:"description" form:"description" query:"description" validate:"required"`
	Items []struct{
	        CategoryID uint `json:"category_id" form:"category_id" query:"category_id" validate:"required"`
		Images []*multipart.FileHeader `json:"images" form:"images" query:"images"`
		ID 		uint `json:"id" form:"id" query:"id" validate:""`
		Barcode  string `json:"barcode" form:"barcode" query:"barcode"  validate:"required"`
		SellingPrice float64  `json:"selling_price" form:"selling_price" query:"selling_price" validate:"required"`
		Height 	float32	`json:"height" form:"height" query:"height" validate:"required"`
		Length 	float32	`json:"length" form:"length" query:"length" validate:"required"`
	} `json:"stockItems" form:"stockItems" query:"stockItems" validate:"required,gt=0,dive,required"`
}

Please use code block formatting when adding code, otherwise it's an unreadable mess.
Maybe you can check the docs for binding and request at https://echo.labstack.com/guide/
