Question

I’m using the codeigniter session class (autoload). How can I set initialize values? I need this because I want to initialize the default language.

Best regards …

To load initialize data into your session, you can use hooks.

You can use a post_controller_constructor hook (in the pre_controller hook, the session may not loaded yet).

Open up config/hooks.php and add this:

$hook['post_controller_constructor'][] = array(
                                'class'    => 'SessionData',
                                'function' => 'initializeData',
                                'filename' => 'SessionData.php',
                                'filepath' => 'hooks',
                                'params'   => array()
                                );

And then in the hooks folder make a file called SessionData.php containing the following:

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class SessionData{
    var $CI;

    function __construct(){
        $this->CI =& get_instance();
    }

    function initializeData() {
          // This function will run after the constructor for the controller is ran
          // Set any initial values here
          if(!$this->session->userdata('language')){
             $this->CI->session->set_userdata('language', 'English');
          }
    }
}
?>
