Pass filename of the file selected for upload using enctype="multipart/form-data" to a struct field in Golang

My application uses the html code snippet for the form to upload a file

<form  method="POST" action="/addproduct" enctype="multipart/form-data">
        <label class="form-control-label" for="productimage"></label>
        {{with .Errors.image}}
        <div class="alert alert-danger">
            {{.}}
        </div>
        {{end}}		
		
		<input type="file" name="productimage" id = "productimage" multiple="multiple" class = "btn btn-danger">
					
        <input type="submit" name="submit" value="Submit" class = "btn btn-info">
    </form>

I need to grab the filename of the uploaded file and pass it to a struct field in Golang.

	file, header, err := r.FormFile("productimage")
	defer file.Close()
	if err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
	}
	var pimage = header.Filename 

p := &Product{
	Puid:     Puid(),
	Pname:    r.FormValue("productName"),
	Quantity: r.FormValue("quantity"),
	Price:    r.FormValue("price"),
	Image:    pimage,
}

I am trying to pass the name of the file selected for uploaded to 'image' field of the struct 'Product'. Any suggestions on how this can be done?

Instead of calling r.FormFile(), you could instead try:

mpr, _ := r.MultipartReader()
filePart, _ := r.NextPart()
fileName := filePart.FileName()

However, I would check the errors
