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 ).

How to install CodeIgniter Download CodeIgniter : Click here:  Configuring the base URL: Open the config.php file located in application/config/config.php directory Look for the line that says $config['base_url'] = ''; If the base_url is blank, CodeIgniter will try to guess the root URL but this is not guaranteed to always work so it’s better to explicitly set it. Enter our project URL as shown below $config['base_url'] = 'http://localhost/package_name/'; HERE, “'http://localhost/package_name/'” will be returned when you call the base URL helper function. We will talk more about the base URL later.
