Предполагая, что это ваша структура:
войдите в index.php
и измените следующие переменные
/*
*---------------------------------------------------------------
* SYSTEM DIRECTORY NAME
*---------------------------------------------------------------
*
* This variable must contain the name of your "system" directory.
* Set the path if it is not in the same directory as this file.
*/
$system_path = 'ci/system';
/*
*---------------------------------------------------------------
* APPLICATION DIRECTORY NAME
*---------------------------------------------------------------
*
* If you want this front controller to use a different "application"
* directory than the default one you can set its name here. The directory
* can also be renamed or relocated anywhere on your server. If you do,
* use an absolute (full) server path.
* For more info please see the user guide:
*
* https://codeigniter.com/user_guide/general/managing_apps.html
*
* NO TRAILING SLASH!
*/
$application_folder = 'ci/application';
/*
*---------------------------------------------------------------
* VIEW DIRECTORY NAME
*---------------------------------------------------------------
*
* If you want to move the view directory out of the application
* directory, set the path to it here. The directory can be renamed
* and relocated anywhere on your server. If blank, it will default
* to the standard location inside your application directory.
* If you do move this, use an absolute (full) server path.
*
* NO TRAILING SLASH!
*/
$view_folder = './';
тогда вы можете просто загрузить просмотр как обычно $this->load->view('welcome_message');
Я бы также предложил не использовать определения camelCase для файлов и переключиться на Something_more_codeigniter_friendly.php. Это требуется для контроллеров.
