        ]);

        if ($event->user_id != $comment->user_id) {
            $user = User::find($event->user_id);
            $user->notify(new NewCommentEvent($comment));
        }



        Toastr::success('Comment post with success','', ["positionClass" => "toast-top-center"]);
        return redirect()->back();
    }

my CommenRequest

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Support\Facades\Auth;

class CommentRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return Auth::check();
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'comment' => 'required|max:2000',
        ];
    }
}

And what is your question? Is there any problem with all that code? — Nico Haase

In your controller: the variable $comment is not defined.

From Laravel docs:

The create method returns the saved model instance.

so the solution is:

$comment = Comment::create([
            'comment' => $request->comment,
            'user_id' => Auth::id(),
            'event_id' => $event->id
        ]);

you have not defined your $comment, you just created a comment. This is throwing the error

$comment = Comment::create([
     .
     .
]);

This will fix your issue

The error message was clear. $comment is undefined. Replace your controller code with the follow:

public function store(CommentRequest $request)
    {


    $event = Event::findOrFail($request->event_id);

   // defined comment here
    $comment = Comment::create([
        'comment' => $request->comment,
        'user_id' => Auth::id(),
        'event_id' => $event->id
    ]);

    if ($event->user_id != $comment->user_id) {
        $user = User::find($event->user_id);
        $user->notify(new NewCommentEvent($comment));
    }



    Toastr::success('Comment post with success','', ["positionClass" => "toast-top-center"]);
    return redirect()->back();
}
