Answer 1

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);



     }

 }

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.
