Question

当我在本地服务器中测试时它运行良好，但是当我上传 000webhost 服务器时它显示错误。错误 我的路线：我的路线：$routes->get('/komik/create', 'komik::create');$routes->get('/komik/edit/(:segment)', 'komik::edit/$1');$routes->delete('/komik/(:num)', 'komik::delete/$1');$routes->get('/komik/(:any)', 'Komik::detail/$1');有人可以帮助我吗？一个错误Controller or its method is not found: \App\Controllers\komik::create我尝试在 url 中隐藏详细信息的方法，它在本地服务器中运行良好，但为什么当我上传到网络托管时它显示错误

Answer 1

你好，我只是看看你的代码，我认为 codeigniter 4 在检测路由方面更强大。根据您的路线，您甚至不需要创建这些路线。调用您的控制器和方法而不创建路由。

就这个

namespace App\Controllers;

use App\Models\Data_KomikModel;

use App\Models\GambarModel;

use App\Models\SoalModel;

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 \App\Models\Data_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' => \Config\Services::validation()

        ];

        if (empty($data['komik'])) {

            throw new \CodeIgniter\Exceptions\PageNotFoundException('Judul Komik ' . $slug . 'Tidak Ditemukan');

        }

        return view('dataKomik/detail', $data);

    }

    public function create()

    {

        // session();

        $data = [

            'title' => 'Form Tambah Data Komik',

            'validation' => \Config\Services::validation()

        ];

        return view('dataKomik/create', $data);

    }

    public function save()

    {

        if (!$this->validate([

            'judul' => [

                'rules' => 'required|is_unique[data_komik.judul]',

                'errors' => [

                    'required' => '{field} komik harus diisi.',

                    'is_unique' => '{field} komik sudah terdaftar'

                ]

            ],

            'sampul' => [

                'rules' => 'max_size[sampul,1024]|is_image[sampul]|mime_in[sampul,image/jpg,image/jpeg,image/png]',

                'errors' => [

                    'max_size' => 'ukuran gambar terlalu besar',

                    'is_image' => 'yang anda pilih bukan gambar',

                    'mime_in' => 'yang anda pilih bukan gambar',

                ]

            ]

        ])) {

            // $validation = \Config\Services::validation();

            // return redirect()->to('/komik/create')->withInput()->with('validation', $validation);

            return redirect()->to('/komik/create')->withInput();

        }

        $fileSampul = $this->request->getFile('sampul');

        if ($fileSampul->getError() == 4) {

            $namaSampul = 'default.jpg';

        } else {

            // $namaSampul = $fileSampul->getName();

            $namaSampul = $fileSampul->getRandomName();

            $fileSampul->move('img', $namaSampul);

        }

        $slug = url_title($this->request->getVar('judul'), '-', true);

        $this->komikModel->save([

            'judul' => $this->request->getVar('judul'),

            'slug' => $slug,

            'sampul' => $namaSampul,

        ]);

        session()->setFlashdata('pesan', '<div class="alert alert-success alert-dismissible fade show" role="alert">

        Data Berhasil Ditambahkan.

        <button type="button" class="close" data-dismiss="alert" aria-label="Close">

          <span aria-hidden="true">&times;</span>

        </button>

      </div>');

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

    }

    public function delete($id)

    {

        $komik = $this->komikModel->find($id);

        if ($komik['sampul'] != 'default.jpg') {

            unlink('img/' . $komik['sampul']);

        }

        $this->komikModel->delete($id);

        session()->setFlashdata('pesan', '<div class="alert alert-success alert-dismissible fade show" role="alert">

        Data Berhasil Dihapus.

        <button type="button" class="close" data-dismiss="alert" aria-label="Close">

          <span aria-hidden="true">&times;</span>

        </button>

      </div>');

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

    }

    public function edit($slug)

    {

        $data = [

            'title' => 'Form Ubah Data Komik',

            'validation' => \Config\Services::validation(),

            'komik' => $this->komikModel->getKomik($slug)

        ];

        return view('dataKomik/edit', $data);

    }

    public function update($id)

    {

        $komikLama = $this->komikModel->getKomik($this->request->getVar('slug'));

        if ($komikLama['judul'] == $this->request->getVar('judul')) {

            $rule_judul = 'required';

        } else {

            $rule_judul = 'required|is_unique[data_komik.judul]';

        }

        if (!$this->validate([

            'judul' => [

                'rules' => $rule_judul,

                'errors' => [

                    'required' => '{field} komik harus diisi.',

                    'is_unique' => '{field} komik sudah terdaftar'

                ]

            ],

            'sampul' => [

                'rules' => 'max_size[sampul,1024]|is_image[sampul]|mime_in[sampul,image/jpg,image/jpeg,image/png]',

                'errors' => [

                    'max_size' => 'ukuran gambar terlalu besar',

                    'is_image' => 'yang anda pilih bukan gambar',

                    'mime_in' => 'yang anda pilih bukan gambar',

                ]

            ]

        ])) {

            return redirect()->to('/komik/edit/' . $this->request->getVar('slug'))->withInput();

        }

        $fileSampul = $this->request->getFile('sampul');

        $komik = $this->komikModel->find($id);

        if ($fileSampul->getError() == 4) {

            $namaSampul = $this->request->getVar('sampulLama');

        } else {

            $namaSampul = $fileSampul->getRandomName();

            $fileSampul->move('img', $namaSampul);

            if ($komik['sampul'] != 'default.jpg') {

                unlink('img/' . $this->request->getVar('sampulLama'));

            }

        }

        $slug = url_title($this->request->getVar('judul'), '-', true);

        $this->komikModel->save([

            'id_komik' => $id,

            'judul' => $this->request->getVar('judul'),

            'slug' => $slug,

            'sampul' => $namaSampul,

        ]);

        session()->setFlashdata('pesan', '<div class="alert alert-success alert-dismissible fade show" role="alert">

        Data Berhasil Diubah.

        <button type="button" class="close" data-dismiss="alert" aria-label="Close">

          <span aria-hidden="true">&times;</span>

        </button>

      </div>');

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

    }

    //--------------------------------------------------------------------

}

然后在你的链接中使用这个

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

或者

如果您仍然需要使用路由，请删除路由前面的正斜杠，而不是

$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');

用这个

$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');

我认为这有帮助！如果不引起我的注意

Answer 2

注意区分大小写，更改：

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

到 ：

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