Codeigniter控制器和路由

I am trying to build a very simple web app using codeigniter, for now I am trying to build static pages for both the website and the admin area.

but any routing is giving

404 page

except the home controller.

I have 2 main folders containing the web pages, one is for the user

application/views/pages/home.php

and the other is for the admin.

application/views/admin/dashboard.php

I can access the home page, but I can't access the admin page.

here is the Pages controller:

<?php
class Pages extends CI_Controller {
  public function view($page = 'home')
  {
    $this->load->helper('html');
          if ( ! file_exists(APPPATH.'views/pages/'.$page.'.php'))
          {
             show_404();
          }

          $data['title'] = ucfirst($page); // Capitalize the first letter
          $this->load->view('templates/header', $data);
          $this->load->view('pages/'.$page, $data);
          $this->load->view('templates/footer', $data);
  }
}
?>

and here is the admin controller

<?php
class Admin extends CI_Controller {
  public function view($admin = 'dashboard')
  {
          if ( ! file_exists(APPPATH.'views/admin/'.$admin.'.php'))
          {
                show_404();
          }
          $data['title'] = ucfirst($page);/* should be there*/
          $this->load->view('admin/'.$admin, $data);
  }
}
?>

and here is the routes

$route['admin'] = 'admin/dashboard';
$route['default_controller'] = 'pages/view';
$route['(:any)'] = 'pages/view/$1';
$route['translate_uri_dashes'] = FALSE;

I can access the home page, but I can't access the admin page. any help, please?

Hope this will help you :

Make sure you have loaded url helper and .htaccess and set base_url in config.php

Your config.php

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

In autoload.php

$autoload['helper'] = array('url');

.htaccess file should be like this :

Options +FollowSymlinks -Indexes
RewriteEngine on
DirectoryIndex index.php
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]

place .htaccess file in your project_folder

Replace

$route['admin'] = 'admin/dashboard';

with this :

$route['admin'] = 'admin/view';

route.php should be like this :

$route['admin'] = 'admin/view';
$route['default_controller'] = 'pages/view';
$route['(:any)'] = 'pages/view/$1';
$route['translate_uri_dashes'] = FALSE;

Access url like this :

http://localhost/project_folder/
http://localhost/project_folder/admin

<?php

          {
                show_404();
          }else{
           $data['title'] = ucfirst($page);/* should be there*/
          $this->load->view('admin/'.$admin, $data);
          }
