Codeigniter - 找不到404页面

Question

I'm using Codeigniter. Everything is fine until when I'm create new controller named user_authentication.php (located on http://localhost/etalasekursusci/index.php/user_authentication ). When I try to open this controller, the browser said "404 Page Not Found. The page you requested was not found". My controller files on http://localhost/etalasekursusci/index.php/controller and http://localhost/etalasekursusci/index.php/user work fine, just this one which fails.

(FYI, I copy the user_authentication.php file from my friend. And if I copy the script inside user class to user_authentication class, the user_authentication.php can be accessed...)

The /application/.htaccess file :

<IfModule authz_core_module>
    Require all denied
</IfModule>
<IfModule !authz_core_module>
    Deny from all
</IfModule>

The /application/config/config.php file :

$config['base_url'] = 'http://localhost/etalasekursusci/';

The /application/config/routes.php file :

$route['default_controller'] = 'controller';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

The /application/controllers/user.php file (can be accessed):

<?php
class user extends CI_Controller {
public function __construct()
{
    parent::__construct();

    $this->load->model('user_model');
}

public function index()
{
    $this->load->library('form_validation');

    $this->form_validation->set_error_delimiters('<div class="error">', '</div>');

    $this->form_validation->set_rules('nama', 'Nama Kursus', 'required|min_length[5]|max_length[20]');

    $this->form_validation->set_rules('alamat', 'Alamat Kursus', 'required|min_length[5]|max_length[40]');

    if ($this->form_validation->run() == FALSE)
    {
        $this->load->view('register_user');
    }
    else
    {
        $data = array(
        'lembaga' => $this->input->post('nama'),
        'alamat' => $this->input->post('alamat'),
        'paketkursus' => $this->input->post('paket'),
        'lokasi' => $this->input->post('lokasi'),
        'harga' => $this->input->post('biaya')
        );

        $this->user_model->insert_userinfo($data);

        $this->load->view('tambahberhasil');

    }
}
}

The /application/controllers/user_authentication.php file (which can't be accessed):

}
}else{

}
}


public function logout() {

);
$this->session->unset_userdata('logged_in', $sess_array);
$data['message_display'] = 'Anda sudah Log Out !';

}

}

Any ideas?

Answer 1

Since you have defined base url as

$config['base_url'] = 'http://localhost/etalasekursusci/';

Please try url http://localhost/etalasekursusci/user_authentication without index.php

OR Define base_url in config as below with index.php

$config['base_url'] = ' http://localhost/etalasekursusci/index.php ';

Please post controller code, If you can.

Answer 2

In Codeigniter 3 your class names must start with an uppercase letter as should their filename.

You should try rename user_authentication.php to User_authentication.php and change the opening lines to:

<?php
class User_authentication extends CI_Controller {

similarly, the user.php should be changed to User.php and its opening lines to:

<?php
class User extends CI_Controller {

The class documentation explaining this can be found here
