Mahdi.Pishguy:

in laravel5 my code as :

$data = Contents::whereSlug($content)->orWhere('id', '=', $content)->first();

maybe return null. i want to manage that with Custom Message and show that on view. for example:

Route::get('/showContent/{content}', function ($content) {
    $data = Contents::whereSlug($content)->orWhere('id', '=', $content)->first();
    if ($data == null) {
        abort(404, 'content not found');
    }
    $serverInformation = ServerInformation::find(1);
    return view('layouts.frontend.pages.showContent', compact(
        'data',
        'serverInformation'
    ));
});

i have errors folder on resources/views/missing.blade.php now i expect this message as content not found show on view by this code:

unfortunately i get this error:

Undefined variable: exception (View: /Applications/XAMPP/xamppfiles/htdocs/alachiqServer/resources/views/errors/missing.blade.php

and render on Handler.php file:

public function render($request, Exception $e)
{
    if ($e instanceof ModelNotFoundException or $e instanceof NotFoundHttpException) {
        if ($request->ajax()) {
            return response()->json(['error' => 'Not Found'], 404);
        }
        return response()->view('errors.missing', [], 404);
    }

    return parent::render($request, $e);
}

how can i resolve this problem?
