Laravel - 在视图中显示我的数组图像，该图像存储在我的数据库中的一个ROW中

I want to display all of my images that is displayed on my database in one ROW. The images are stores in an array in my database so it is in one ROW. Currently in my code the image is not showing and it is UNAVAILABLE

Here is my CONTROLLER

Storing Data

    $this->validate($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';
    }


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

 @foreach($promotions as $promotion)
           <tr>  

            <th><img src="{{ asset('storage/promotion_images/' . $promotion->promotion_image) }}" style="width:50px;height:50px;"></th>
 @endforeach

All you have done for storing images seems okay, what you have to do is explode the image data store in the database. So, change your view code like this:

@foreach($promotions as $promotion)
       <tr>  

        <th>
            @foreach(explode(',' ,$promotion->promotion_image) as $image)
                <img src="{{ asset('storage/promotion_images/' . $image) }}" style="width:50px;height:50px;"><br/>
            @endforeach
        </th>
     </tr>
@endforeach

I think this will work for you. If you have any confusion regarding above code, feel free to ask.

if (count($promotion)) {
        $implodedPromotion = implode(' , ', $promotion);
        $promotionImage = new Promotion;
        $promotionImage->promotion_image = $implodedPromotion;
        $promotionImage->save();

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

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