This data is question and answer. And I have a view like this. I have a function show and showQuestion.
And view like this
//View // no problem on here
<div class="box-body table-responsive no-padding">
<table class="table table-hover">
<tbody><tr>
<th>No</th>
<th>Nama Alat</th>
<th>Waktu</th>
<th>User Input</th>
<th>Action</th>
<th>Tanggal</th>
</tr>
#php
$no=0;
#endphp
#foreach ($pemeliharaan as $i)
<tr>
<td>{{ ++$no }} </td>
<td>{{ $i->alat->nama_alat}}</td>
<td>{{ $i->status}}</td>
<td>{{ $i->user->name}}</td>
<td> Lihat Data</span> </td>//in here redirect to showQuestion
<td>{{ $i->created_at}}</td>
</tr>
#endforeach
</tbody></table>
</div>
viewQuestion (if I click the button on the table will view this data)
#if( !is_null($pemeliharaan) )
<p> Laporan : {{ $pemeliharaan->status }} </p>
<p> Tanggal : {{ $pemeliharaan->created_at }} </p>
<p> Jenis Alat : {{ $pemeliharaan->alat->nama_alat }} </p>
<p> User : {{ $pemeliharaan->user->name }} </p>
<p> pertanyaan : {{ $pemeliharaan['question1'] }} </p>// now showing anything
#endif
#foreach(json_decode($pemeliharaan, true) as $value)
pertanyaan : {{ $value->pertanyaan['question1'] }}
#endforeach //corect me at here
//this is I want to decode this json but i dont
know what i do haha :(
this view (without question and answer) is don't have an error.
this is my controller :
public function show()
{
$pemeliharaan = Pemeliharaan::with(['user','alat'])->get();
return view('users.view',['pemeliharaan' => $pemeliharaan]);
}
public function showQuestion($id)
{
$pemeliharaan = Pemeliharaan::find($id);
$pemeliharaan->pertanyaan = json_decode($pemeliharaan->pertanyaan,true);
return view('users.view_question',compact('pemeliharaan'));
}
Having error like this
Undefined index: alat (View: /var/www/html/new/resources/views/users/view_question.blade.php)
I don't know how to decode and how to view in blade

Answer 1

You need to decode the specific column, not the whole object, try:
public function showQuestion($id)
{
$pemeliharaan = Pemeliharaan::find($id);
$pemeliharaan->pertanyaan = json_decode($pemeliharaan->pertanyaan,true);
return view('users.view_question',compact('pemeliharaan'));
}
And check in the viewQuestion if $pemeliharaan is null or not :
#if( !is_null($pemeliharaan) )
<p> Laporan : {{$pemeliharaan['status']}} </p>
<p> Tanggal : {{ $pemeliharaan['created_at'] }} </p>
<p> Jenis Alat : {{ $pemeliharaan->alat->nama_alat }} </p>
<p> User : {{ $pemeliharaan->user->name}} </p>
<p> pertanyaan : {{ $pemeliharaan['question1'] }} </p>
#endif
To parse all the Questions/Answers try :
#foreach($pemeliharaan->pertanyaan as $key => $value)
pertanyaan : {{ $key . ' - ' . $value}}
#endforeach
Play with this as you want.

Answer 2

you can use the json mutator to cast the field in a json directly :
https://laravel.com/docs/5.8/eloquent-mutators#array-and-json-casting
protected $casts = [
'pertanyaan' => 'json',
];
Then if you want to display it, I advice you this following :
create a blade file components/json.blade.php :
#if (!is_string($value))
#foreach($value as $key => $value)
<span class="ml-3"><strong>{{ ucfirst($key) }}</strong> : #include('components.json')</span>
#endforeach
#else
{{ $value }}
#endif
Then in your main file :
#include('components.json', ['value' => $pemeliharaan->pertanyaan])
(I have no idea of what pemeliharaan AND pertanyaan means, so maybe it's mess up, but you should pass your json converted to array as a value
The result will be a recursive list of all your json data presented that way :
Question1 : Periksa kondisi kelistrikan dan kabel
Answer1 : false
Question2 : Periksa kondisi kabel dan tempat sambungan
Answer2 : false
