Controller or its method is not found: AppControllerskomik::create

i try to hide detail’s method in url, it’s running fine in local server but why it’s showing an error when i uploaded to web hosting

Answer

Hello I just look at your code i think codeigniter 4 is more powerful of detecting routes. Base on your route you don’t even need to create those routing. Call your controller and methods without creating routing.

Here is it

namespace AppControllers;

use AppModelsData_KomikModel;
use AppModelsGambarModel;
use AppModelsSoalModel;

class Komik extends BaseController
{
    protected $komikModel;
    public function __construct()
    {
        $this->komikModel = new Data_KomikModel();
        $this->gambarModel = new GambarModel();
        $this->soalModel = new SoalModel();
        // dd(session()->get('email'));

    }
    public function index()
    {
        if (!session()->has('username')) {
            return redirect()->to('/auth/login');
        }
        // $komik = $this->komikModel->findAll();
        $data = [
            'title' => 'Data Komik',
            'komik' => $this->komikModel->getKomik()
        ];
        // $komikModel = new AppModelsData_KomikModel();
        // $komikModel = new Data_KomikModel();

        return view('dataKomik/komik', $data);
    }

    public function detail($slug)
    {
        $komik = $this->komikModel->getKomik($slug);
        $gambar = $this->gambarModel->getGambar($slug);
        $soal = $this->soalModel->getDataSoal($slug);
        // dd($soal);
        $data = [
            'title' => 'Info Komik',
            'komik' => $komik,
            'gambar' => $gambar,
            'soal' => $soal,
            'validation' => ConfigServices::validation()
        ];

        if (empty($data['komik'])) {
            throw new CodeIgniterExceptionsPageNotFoundException('Judul Komik ' . $slug . 'Tidak Ditemukan');
        }

      </div>');
        return redirect()->to('/komik');
    }
    //--------------------------------------------------------------------

}

Then in your links use this

<a href="<?= base_url('komik/create')?>"> Create</a>

OR

If you still need to use the routing, remove the forward slash in front of the route that is instead of

$routes->get('/komik/create', 'komik::create');
$routes->get('/komik/edit/(:segment)', 'komik::edit/$1');
$routes->delete('/komik/(:num)', 'komik::delete/$1');
$routes->get('/komik/(:any)', 'Komik::detail/$1');

Use this

$routes->get('komik/create', 'komik::create');
$routes->get('komik/edit/(:segment)', 'komik::edit/$1');
$routes->delete('komik/(:num)', 'komik::delete/$1');
$routes->get('komik/(:any)', 'Komik::detail/$1');

I think this helps! if not call my attention
