#section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">{{ __('DozentAnsicht') }}</div>
<div class="card-body">
#if (session('status'))
<div class="alert alert-success" role="alert">
{{ session('status') }}
</div>
#endif
<table id="statisticforteacher" class="table-responsive">
<thead>
<th>Id</th>
<th>FrageBezeichnung</th>
<th>Kapitel</th>
<th>richtige Antwort</th>
<th>falsche Antwort</th>
<th>Richtige Rate</th>
</thead>
<tbody>
#foreach($daten as $value)
<tr>
<td>{{$value -> Id}}</td>
<td>{{$value -> FrageBezeichnung}}</td>
<td>{{$value -> Kapitel}}</td>
<td>{{$value -> richtigeAntwort}}</td>
<td>{{$value -> falscheAntwort}}</td>
<td>{{$value -> richtigeRate}}</td>
</tr>
#endforeach
</tbody>
</table>
</div>
</div>
</div>
</div>
</div>
</div>
#endsection
I want to show the table in the view, but it didn't work in statisticA but it works in statistic
I don't know what happen
my controller
<?php
namespace App\Http\Controllers;
use DB;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class StatisticsController extends Controller
{
//
public function statistic(){
$data =DB::table('statisticforteacher') -> get();
return view('/statistics',compact('data'));
}
public function statisticA(){
$daten =DB::table('statisticforteacher') -> get();
return view('/statisticsA',compact('daten'));
}
}
has anyone a idea?

Answer 1

You have in route file two different routes with same url but different controllers. As in order when Laravel read the file, get the last matched route, for that reason you have the issue. So, fix your routes statements and must work
Route::get('/statisticsA', 'StatisticsController#statisticA');
Route::get('/statisticsA', [
'uses' => 'PagesController#getStatisticsAdmin',
'as' => 'statisticsA',
'middleware' => 'roles',
'roles' => ['Author','Admin']
])->middleware('auth');
