This Simple tutorial will primarily focus on: Model-View-Controller basics Routing basics Form validation Performing basic database queries using “Query Builder” Adding logic to the controller : Create a file at application-package_folder/controllers/Pages.php with the following code. <?php class Pages extends CI_Controller { public function view($page = 'home') { } } You have created a class named Pages , with a view method that accepts one argument named $page . The Pages class is extending the CI_Controller class. This means that the new pages class can access the methods and variables defined in the CI_Controller class ( system/core/Controller.php ).
