Laravel6 multi dimensional array validation

Question

I am creating a recipe posting application with Laravel6.

I have implemented a mechanism to dynamically add an image submission form in JavaScript.

I set the validation in FormRequest, but the mandatory input validation for dynamically added form fields does not work.

blade

<input type="file" name="upload_image[cooking_image][]" class="howto-image" style="display:none" accept="image/*">

FormRequest

 public function rules(Request $request)
    {       
        return [
            'upload_image.cooking_image.*' => 'required|image|mimes:jpeg,png,jpg',
        ];
    }

But the following works.

FormRequest

 public function rules(Request $request)
    {       
        return [
            'upload_image.cooking_image.0' => 'required|image|mimes:jpeg,png,jpg',
            'upload_image.cooking_image.1' => 'required|image|mimes:jpeg,png,jpg',
            'upload_image.cooking_image.2' => 'required|image|mimes:jpeg,png,jpg',
            'upload_image.cooking_image.3' => 'required|image|mimes:jpeg,png,jpg',
            'upload_image.cooking_image.4' => 'required|image|mimes:jpeg,png,jpg',
        ];
    }

I want to make mandatory input validation work for all dynamically added form input fields.

Answer 1

I think it sometimes not really possible to make it easily dynamic. Personally, in those case, I update my rules array on the fly.

I think this should help you : How to use required_if on file array fields with an array for first argument?

Good luck!
