How can I make this an implode function using array of images? I am getting an error of:

implode(): Invalid arguments passed

My controller:

    public function store(Request $request)

{

    $this->validate($request, [

        'promotion_image' => 'required'

    ]);



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

    {   

        //Handle File Upload



        $promotion = ;

        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';

    }



    foreach ($promotion as $key => $value) {

        $promotionImage = new Promotion;

        $promotionImage->promotion_image = implode(' , ',$value);

        $promotionImage->save();

    }

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

}

My view:

 @foreach($promotions as $promotion)

           <tr>  



      //HERE IS WHERE THE IMAGE ARE VIEWED      <th><img src="{{ asset('storage/promotion_images/' . $promotion->promotion_image) }}" style="width:50px;height:50px;"></th>

            <th><a href="/admin/airlineplus/promotions/{{ $promotion->id  }}/edit" class="fa fa-edit btn btn-primary btn-lg"></a></th>



         </tr> 

         @endforeach

If I get you right, try without foreach loop

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.');

Supplemental:

If you have that value in your view and want to show those images, you should do the next:

@foreach($promotions as $promotion)

    @php

        $imagesImploded = $promotion->promotion_image;

        $imagesExploded = explode(',', $imagesImploded);

    @endphp

    <tr>

        @foreach($imagesExploded as $image)  

        <th><img src="{{ asset('storage/promotion_images/' . trim($image)) }}" style="width:50px;height:50px;"></th>

        @endforeach

        <th><a href="/admin/airlineplus/promotions/{{ $promotion->id  }}/edit" class="fa fa-edit btn btn-primary btn-lg"></a></th>

    </tr> 

@endforeach
