How to show 404 whenever/wherever I want - Leo - 04-15-2020
Hello. In my site I have some pages that I only want a logged in administrator to see. If the admin is not logged in I don't want to show the typical login page or some error, I want to show error 404. In CodeIgniter 3 we could type show_404() wherever we wanted in the controller - and as soon as the code got to it - bam! 404. How can I do this in CI 4?

I believe this should meet ...
PHP Code:
if //anything you want
{
return redirect()->to('/errors/nodata');
exit;
}
//my 404 page is customized.

That code does't work for me. The whole syntax
return redirect()->to('/wherever');
is not working for me, at least not in that controller. But even if it did wouldn't it just redirect to /errors/nodata ??
I don't want to redirect though. I just want to show 404 page not found with the uri they were trying to access.
Scenario: They are an unauthorized user probing through my site, theres a url called /edit_products - that should only be viewable by admins.
If they are unauthorized as an admin they see 404 on that link.

There are options through .htaccess, also.
/errors/nodata => It was just an example, I don't know if 404 routing is customized by you.
I warned you that my 404 page is customized.
I changed the router configuration in app/config/routes.php
PHP Code:
$routes->setDefaultNamespace('App\Controllers');
$routes->setDefaultController('Home');
$routes->setDefaultMethod('index');
$routes->setTranslateURIDashes(false);
$routes->set404Override(function() // <= changed
{
$header = array (
'icon' => 'favicon',
'css' => 'nodata',
'title' => 'Page not found - wdeda',
'placeholder' => 'Search'
);
echo view('templates/headerr', $header);
echo view('/content/error_404');
echo view('templates/footer');
});
$routes->setAutoRoute(true);

Thanks, I made a custom 404 too with your router example.
But still, how do I show some users 404 and others the real content - without changing the url...
.htaccess options? What kind of options?

Once you've customised your response, can't you simply invoke it by using 'throw'?

Thank YOU kind sir!
