Gathering database settings globally

Well, I assume you are autoloading your library in your autoload.php config file.

If so, then in your controllers you just access it like:
$this->global_lib->some_method();

or $some_param = $this->global_lib->function_that_returns_something($some_var);
or $some_param = $this->global_lib->some_public_var_of_lib_object;

I would write your library like:

Code:

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

class Global_lib {

    private $CI;  //we will access CI from this var
    
    public $site_theme = 'theme_path';  //default value
    public $user_theme = 'user selected theme'; //default value
    
    
    public function __construct()
    {
        $this->CI =& get_instance();        
        log_message('debug', 'Global_lib: Loaded');
    }
    //some setters
    public function set_theme($theme)
    {
        $this->site_theme = $theme;
    }
    public function set_user_theme($theme)
    {
        $this->user_theme = $theme;
    }
    //a getter
    public function get_globals()
    {
        return array('site_theme' => $this->site_theme, 'user_theme' => $this->user_theme);
    }
    public function fetch_theme()
    {
       //maybe fetch the theme for the current user from the database?
        $theme = $this->CI->db
          ->select('code')
          ->where('theme_name', $this->user_theme)
          ->get('theme_table')
          ->result_array();
        return $theme;
    }
}

Then, in your controller, you just

Code:

$settings = $this->global_lib->get_globals();

echo $settings['user_theme'];
// echos "user selected theme"

$this->global_lib->set_user_theme('new theme');
echo $this->global_lib->user_theme; //echos "new theme";

$data['theme'] = $this->global_lib->fetch_theme();

//load the view with our theme data
$this->load->view('admin/some_viewfile', $data);

Hope it gives you some ideas.
