Passing variables to all views.

He said they come from the database. Not all settings belong in a config file. Most clients don't have the ability to go editing php files.

I do something like that with application specific config settings. I just create a library that triggers a method in __construct() that gets the data from the db and creates variables from them. That library gets autoloaded so the variables are available globally.

It's fairly basic...something like:

PHP Code:

class Site_settings {

  //holds the CI instance
  protected $CI;

  //the array the settings will be stored as
  public $site_config = array();

  //
  public function __construct()
  {
    //load CI instance
    $this->CI =& get_instance();

    //fire the method loading the data
    $this->init();
  }

  public function init()
  {
    //load the model that gets the data
    $this->CI->load->model('site_config_model');

    //retrieve/set the data
    $this->site_config = $this->CI->site_config_model->get_settings(); //returns an associative array of config settings
  }
} 


Now if you autoload the site_settings library, $this->site_config is the array that's available to all other controllers/models/views/etc.

PHP Code:

echo $this->site_settings['company_slogan'];
