Answer 1

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);
}
}
