Displaying json data to view as String or array

Question

New to Laravel and feel that I'm missing something important here. I am uploading and saving multiple files to a folder and saving an array of the images names to the database(simple enough). Currently saving the images name in the json_encode() format so they are formatted like so["kittyTest.jpeg","kitty_2.jpeg","kitty_3.jpeg"]. So when I try and print them out to the view I get them in the json format and am trying to display them in an array formate or in some way that I can use the filename for the source image. Any help or guidance would be much appreciated.

Controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Form;
use DB;

class FormController extends Controller
{
 public function index()
{
    $images = DB::select('select * from forms');

    //dd(json_decode($images[0]->filename));

    return view('index', ['images'=> $images]);
}

public function create()
{
    return view('create');
}

public function store(Request $request)
{
    $this->validate($request, [
        'filename' => 'required',
        'filename.*' => 'image|mimes:jpeg,png,jpg,gif,svg|max:2048'
    ]);

    if ($request->hasFile('filename')) {
        foreach ($request->file('filename') as $image) {
            $name = $image->getClientOriginalName();
            $image->move(public_path().'/images/', $name);
            $data[] = $name;
        }
    }

    $form = new Form();
    $form->filename = json_encode($data);
    $form->save();

    return back()->with('success', 'Your images have been uploaded');
}

}

View

<body>
<div class="container">


<h3 class="jumbotron">Laravel Multiple File Upload</h3>

<p>Here are the images we have in the database</p>

<ul class="list-group">
@foreach ($images as $image)
    <li class="list-group-item">
        {{ $image->filename }}
    </li>
@endforeach
</ul>
</div>


</body>

<ul class="list-group">
@foreach ($images as $image)
    @php $image_array = json_decode($image->filename,true); @endphp
    @foreach ($image_array as $img)
     <li class="list-group-item">

        {{ $img }}
     </li>
    @endforeach
@endforeach
</ul>

In your controller use array_map to json_decode every image filenames and then use second foreach in your view file.

Controller

public function index()
{
    $images = DB::select('select * from forms');

    array_map(function($a) { 
        $a->filename = json_decode($a->filename); 
        return $a; 
    }, $images);

    return view('index', compact($images)); // you can use compact function here
}

View

<ul class="list-group">
@foreach ($images as $image)
    <li class="list-group-item">
        @foreach ( $image->filename as $file)
        {{ $file }}
        @endforeach
    </li>
@endforeach
</ul>

Edit: You can also try cast to array, then you dont need to worry about mapping it in your controller file.
