                   'slug' => $slug,
                   'penulis' => $this->request->getVar('penulis'),
                   'penerbit' => $this->request->getVar('penerbit'),
                   'sampul' => $this->request->getVar('sampul')
              ]);
   
              session()->setFlashData('pesan', 'Data berhasil di tambahkan!');
   
              return redirect()->to('/komik');
         }
    }

any suggestion will be appreciated

Hi
where is the route /komik in your routes file ?

Hi
where is the route /komik in your routes file ?

you mean file location?
in app/Controllers/komik

in the
routes.php :

PHP Code:

$routes->get('/', 'pages::index');

$routes->get('/komik/create', 'komik::create');
$routes->get('/komik/(:segment)', 'komik::detail/$1'); 


add:

$routes->get('/komik/', 'komik::index');


this is the routes /komik in your routes file, the missing route (i think)

in the
routes.php :

PHP Code:

$routes->get('/', 'pages::index');

$routes->get('/komik/create', 'komik::create');
$routes->get('/komik/(:segment)', 'komik::detail/$1'); 


add:

$routes->get('/komik/', 'komik::index');


this is the routes /komik in your routes file, the missing route (i think)

still not working

Show me, the file structure to use.

Take off all the beginning / slashes and it should work.

PHP Code:

$routes->get('/', 'pages::index');

$routes->get('komik/', 'Komik::index');
$routes->get('komik/create', 'Komik::create');
$routes->get('komik/(:segment)', 'Komik::detail/$1'); 


Also your controller name should be capitalized,'Komik::index' .

PHP Code:

// class name must have the first letter capitalized
class Komik extends BaseController 


What did you Try? What did you Get? What did you Expect?

What if :

return redirect()->to(base_url());

return redirect()->to(base_url('komik/'));

try and see
did you try other things ?

I want to see complete file structure, is possible?
