You can find everything you are looking for in the manual.

If you still have any problems, you NEED to post some code and what URL you try to access.

I'm not sure what your root url really are. I guess that the picture provided are 'sma' but you are trying to load a lib folder for Javascript that's not even included in the folder...

If the root folder indeed are inside 'sma' this should work.

In app\config\config.php:

Code:
$config['base_url'] = 'http://localhost/sma/'

$config['index_page'] = '';

index.php:

Code:
$system_path = 'system';

$application_folder = 'app';

$view_folder = '/absolute/path/to/your/themes/folder';

$view_folder = 'C:/absolute/path/to/your/themes/folder';

.htaccess:

Code:
<IfModule mod_rewrite.c>

   RewriteEngine on

   RewriteCond $1 !^(index\.php|assets|files|update|updatepos|robots\.txt)

   RewriteCond %{REQUEST_FILENAME} !-f

   RewriteCond %{REQUEST_FILENAME} !-d

   RewriteRule ^(.*)$ index.php/$1 [L,QSA]

</IfModule>

If it's not working or you already have this set it's your app\config\routes.php that's the problem.

Can you load the default controller?
http://localhost/sma/

You can name a different view folder location in the index.php file look in there.

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

Default controller is welcome: Ok.
In app\config\config.php: Ok
.htaccess: Ok
$view_folder = 'themes';

when update $view_folder to absolute path show error 500.

Thanks by your help

***jreklund*** · 01-12-2018, 07:41 AM

Have you modified the view() function inside the Welcome controller?
Generally you ignore the view_folder name, so it should look like this.

PHP Code:
$this->load->view('default/views/show_grid',$data); // For circle 404 page 

You can also change the debug/log option inside app\config\config.php to see all error messages.
Logs are located in app\logs\

PHP Code:
$config['log_threshold'] = 4; 

If you just specify $view_folder = 'themes'; it will look inside app folder after it, not the root folder. Do you have a themes folder inside app too?

Can you load your site with the following URL? If so, your webbserver aren't loading your .htaccess file.
http://localhost/sma/index.php/segway

Can you post your app\config\routes.php

c3media · 01-12-2018, 09:27 AM

Can you load your site with the following URL?
Not: 404 error page not found

Do you have a themes folder inside app too?
Not: THEMES folder it's in root folder.

| -------------------------------------------------------------------------
| URI ROUTING
| -------------------------------------------------------------------------
| This file lets you re-map URI requests to specific controller functions.
|
| Typically there is a one-to-one relationship between a URL string
| and its corresponding controller class/method. The segments in a
| URL normally follow this pattern:
|
| example.com/class/method/id/
|
| In some instances, however, you may want to remap this relationship
| so that a different class/function is called than the one
| corresponding to the URL.
|
| Please see the user guide for complete details:
|
| http://codeigniter.com/user_guide/general/routing.html
|
| -------------------------------------------------------------------------
| RESERVED ROUTES
| -------------------------------------------------------------------------
|
| There are three reserved routes:
|
| $route['default_controller'] = 'welcome';
|
| This route indicates which controller class should be loaded if the
| URI contains no data. In the above example, the "welcome" class
| would be loaded.
|
| $route['404_override'] = 'errors/page_missing';
|
| This route will tell the Router which controller/method to use if those
| provided in the URL cannot be matched to a valid route.
|
| $route['translate_uri_dashes'] = FALSE;
|
| This is not exactly a route, but allows you to automatically route
| controller and method names that contain dashes. '-' isn't a valid
| class or method name character, so it requires translation.
| When you set this option to TRUE, it will replace ALL dashes in the
| controller and method URI segments.
|
| Examples: my-controller/index -> my_controller/index
| my-controller/my-method -> my_controller/my_method
*/
$route['default_controller'] = 'welcome';
$route['404_override'] = 'errors/error_404';
$route['translate_uri_dashes'] = FALSE;

$route['users'] = 'auth/users';
$route['users/create_user'] = 'auth/create_user';
$route['users/profile/(:num)'] = 'auth/profile/$1';
$route['login'] = 'auth/login';
$route['login/(:any)'] = 'auth/login/$1';
$route['logout'] = 'auth/logout';

Try this:

PHP Code:
$view_folder = '../absolute/path/to/your/themes/folder';

Totally forgot you will need to access your Segway class this way.
http://localhost/sma/segway/show_grid
http://localhost/sma/index.php/segway/show_grid

Codeigniter only loads the index() function on default.
You can overwrite the default function by placing this in your route.

PHP Code:
$route['segway'] = 'segway/show_grid'; 

I thought you got a "real" 404 and not Codeigniters 404 messages. But had a look at my dev machine at home now.
