What's the cause Undefined property: stdClass? - php

Question

I don't know what this error cause. I didn't change anything in my codes. But when I go to my search view. It always returns me the undefined property error. This error cause when I tried to foreach all my columns in my table data. I already solve this error not once. Because it cannot find the $id of selected options. But this time I can't fix it.
Error:
Undefined property: stdClass::$id (View: C:\Users\JohnFrancis\LaravelFrancis\resources\views\document\show.blade.php)
View
show.blade.php - This view will list all the values in my tables.
#section ('content')
<div class = "col-md-12">
<table class = "table">
<thead>
<tr>
<th>Title</th>
<th>Content</th>
<th>Category</th>
<th>Sender</th>
<th>Date Received</th>
<th>Action</th>
</tr>
</thead>
<tbody>
#foreach ($documentLists as $list)
<tr class = "info">
<td>{{ $list->title }}</td>
<td>{{ strip_tags(substr($list->content, 0, 50)) }} {{ strlen($list->content) > 50 ? "..." : '' }}</td>
<td>{{ $list->category_type }}</td>
<td>{{ $list->username }}</td>
<td>{{ date('M j, Y', strtotime($list->dateReceived)) }}</td>
<td>
<button type = "submit" class = "btn btn-info">Read</button>
</td>
</tr>
#endforeach
</tbody>
</table>
</div>
#endsection

Answer 1

In below you are not selecting id
$documentLists = DB::table('document_user')->select('documents.title', 'documents.
but calling in your blade {{ route ('document.read', $list->id) }}

Answer 2

$documentLists = DB::table('document_user')->select('documents.id','documents.title', 'documents.content', 'categories.category_type', 'users.username', 'document_user.dateReceived');
You need to select the column documents.id.But you have missed it
