I need to validate my image array as an image and specific image file extensions only. but my request validation to image WONT ALLOW me to use inser nullable values

For example I will add a content and dont want to add images. then the image should contain null that is why i need to have request validation as nullable. But in my experience null value is not allowed and it gives me error why? help me please

here is the error.

The Promotion Image must be an Image

here is my CONTROLLER

 public function store(Request $request)

    {

        $this->validate($request, [

            'promotion_image' => 'image|nullable|max:1999'

        ]);



            $promotion = ;



        if ($request->has('promotion_image'))

        {   

            //Handle File Upload



            foreach ($request->file('promotion_image') as $key => $file)

            {

                // Get FileName

                $filenameWithExt = $file->getClientOriginalName();

                //Get just filename

                $filename = pathinfo( $filenameWithExt, PATHINFO_FILENAME);

                //Get just extension

                $extension = $file->getClientOriginalExtension();

                //Filename to Store

                $fileNameToStore = $filename.'_'.time().'.'.$extension;

                //Upload Image

                $path = $file->storeAs('public/promotion_images',$fileNameToStore);

                array_push($promotion, $fileNameToStore);

            }



            $fileNameToStore = serialize($promotion);

        }

        else

        {

            $fileNameToStore='noimage.jpg';

        }



        if (count($promotion)) {

            $implodedPromotion = implode(' , ', $promotion);

            $promotionImage = new Promotion;

            $promotionImage->promotion_image = $implodedPromotion;

            $promotionImage->save();



            return redirect('/admin/airlineplus/promotions')->with('success', 'Image Inserted');

        }



        return redirect('/admin/airlineplus/promotions')->with('error', 'Something went wrong.');





        }

here is my VIEW

    {!! Form::open(['action'=>'AdminPromotionsController@store', 'method' => 'POST','enctype'=>'multipart/form-data', 'name' => 'add_name', 'id' => 'add_name']) !!}

<div class="form-group">   

    <div class="table-responsive">  

        <table class="table table-bordered" id="dynamic_field">  

           <tr>  

              <td> {{ Form::file('promotion_image')}}</td>



              <td>{{ Form::button('', ['class' => 'btn btn-success fa fa-plus-circle', 'id'=>'add','name'=>'add', 'style'=>'font-size:15px;']) }}</td>

           </tr>  

        </table>  

        {{Form::submit('submit', ['class'=>'btn btn-primary', 'name'=>'submit'])}}

    </div> 

</div>  

{!! Form::close() !!}

No need to add nullable attribute in the validation. just change your validation code like this

$this->validate($request, [

        'promotion_image.*' => 'image|max:1999'

    ]);

If you need user must add image input then you can use required validation rule other wise you don't need such thing.

Above code forces user to add file of type image or nothing at all.

I hope you understand and if any explanation needed, feel free to ask.

You need to validate it as an array:

$validator = Validator::make($request->all(), [

    'photos.profile' => 'required|image',

]);

Take a look laravel docs

you may want to combine it with sometimes which indicates that the current validation rules will apply only if the field is present.
