<thead>
<tr>
    <th scope="col">#</th>
    <th scope="col">Issue</th>
    <th scope="col">begrootte tijd</th>

<tfoot>

    <th scope="col">beschrijving</th>
    <th scope="col">Action</th>
</tr>
</tfoot>
<tbody>
@foreach($issue as $issues)
    <tr>
        <th> {{ $issues->id }} </th>
        <th> {{ $issues->iname }} </th>
        <th> {{ $issues->begroting }} </th>
        <th> {{ $issues->description }} </th>
        <th>
            <a href="" class="btn btn-success"> START</a>
            <a href="" class="btn btn-danger"> STOP</a>

        </th>

    </tr>
@endforeach
</tbody>

DashboardController.php

    <?php

namespace App\Http\Controllers;

use App\Dashboard;
use Illuminate\Http\Request;


class DashboardController extends Controller
{
    public function store(Request $request)
    {
        $this->validate($request,[
            'iname' => 'required',
            'begroting' => 'required',
            'description' => 'required',

        ]);

        $issue = new Issue;

        $issue->iname = $request->input('iname');
        $issue->begroting = $request->input('begroting');
        $issue->description = $request->input('description');

        $issue->save();

        return redirect('/issue')->with('success', 'Issue opgeslagen');



    }

}

the model dashboard.php

    <?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Dashboard extends Model
{
    protected $table = 'issue';
}

The code above doesn't send the Issue to the view. Is this the right code, or haven't you read the documentation? Also, issue is singular (enkelvoudig) and issues is plural (meervoud). The foreach loop should be @foreach ($issues as $issue). — Tim

You should pass the variable to the view.

Lets say you have a HomeController, and want to pass some variable to a view from the controller.

HomeController.php

public function show()
{
    $someVariable = "An Awesome Example";
    return view('example', [
        'someVariable' => $someVariable,
    ]);
}

example.blade.php

<b>{{ $someVariable }}</b>

You have to pass data to a view. Then inside your view you can show that data to the user. In my example I've created a array with the key someVariable and passed $someVariable to the value of that key.

Inside my view I can then use the key to show the value.

You didn't send $issues to blade page, change your DashboardController like this:

<?php

namespace App\Http\Controllers;

use App\Dashboard;
use Illuminate\Http\Request;


class DashboardController extends Controller
{
      public function store(Request $request)
      {
           $this->validate($request,[
              'iname' => 'required',
              'begroting' => 'required',
              'description' => 'required',

           ]);

          $issue = new Issue;

          $issue->iname = $request->input('iname');
          $issue->begroting = $request->input('begroting');
          $issue->description = $request->input('description');

          $issue->save();

          $issues=Dashboard::all();
          return redirect('/issue')->with('success', 'Issue opgeslagen')
                                   ->with('issues',$issues);



     }
