How to display JSON data readable way for users in laravel?

问题

In my controller i have like this

public function show(Document $document){
$doc = DB::table('adjustments')->where('document_id', $document->id)->get();
return view('documents.show',compact('document','doc'));
    }

In my view i have like this

@foreach($doc as $user)
<pre>{{ $user->before}}</pre>
 <pre>{{ $user->after}}</pre>
@endforeach

Im getting output like this

{"title":"Nam beatae tempora nulla magnam accusantium neque eligendi magni.","body":"Unde doloremque omnis aspernatur atque illo quaerat. Esse nulla iure porro error est laborum. Debitis saepe pariatur voluptatem nulla non quam excepturi corporis."}
{"title":"new title","body":"new body"}

but i want show like this Title :.......... Body :......... Title :.......... Body :.........

UPDATED when i try dd($doc);

 array:3 [▼
      0 => {#194 ▼
        +"id": 1
        +"user_id": 1
        +"document_id": 1
        +"before": "{"title":"Nam beatae tempora nulla magnam accusantium neque eligendi magni.","body":"Unde doloremque omnis aspernatur atque illo quaerat. Esse nulla iure porro error est laborum. Debitis saepe pariatur voluptatem nulla non quam excepturi corporis."}"
        +"after": "{"title":"new title","body":"new body"}"
        +"created_at": "2016-05-09 07:16:29"
        +"updated_at": "2016-05-09 07:16:29"
      }
      1 => {#195 ▼
        +"id": 3
        +"user_id": 1
        +"document_id": 1
        +"before": "{"body":"new body"}"

Do something like this:

@foreach($doc as $user)
    <div>
        <strong>Before</strong>
        Title: {{ $user->before->title }}<br />
        Body: {{ $user->before->body }}
    </div>
    <div>
        <strong>After</strong>
        Title: {{ $user->after->title }}<br />
        Body: {{ $user->after->body }}
    </div>
@endforeach

try this :
@foreach($doc as $user)
$before = json_decode($user->before);
$after = json_decode($user->after);
<pre>Title:{{ $before['title'] }}Body:{{ $before['body'] }}</pre>
<pre>Title:{{ $after['title'] }}Body:{{ $after['body'] }}</pre>
@endforeach

You have a json in your code now, You need to decode the variable for access rest of the code.

If your $user->before variable gives {"title":"Nam beatae tempora nulla magnam accusantium neque eligendi magni.","body":"Unde doloremque omnis aspernatur atque illo quaerat. Esse nulla iure porro error est laborum. Debitis saepe pariatur voluptatem nulla non quam excepturi corporis."} then my script must work.

Working example: https://3v4l.org/liLnr

So try with it:

@foreach($doc as $user)
    $before = json_decode($user->before);
    $after = json_decode($user->after);
    <pre>Title:{{ $before->title}}Body:{{ $before->body}}</pre>
    <pre>Title:{{ $after->title}}Body:{{ $after->body}}</pre>
@endforeach
