Where to store a rarerly changing variable for the app?

[eluser]iamzozo[/eluser]
Hi, im facing with a problem:

I would like to store a variable, which i use in different controllers.
This var is changed by the user optionally.
I would like it to be independent from routings to keep further developments flexible.
All users authenticated, who modify this var.

Could you give me an advice?

Thanks!

Use a MY_Controller

Save as ./application/core/MY_Controller.php

Code:

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

class Base_Controller extends CI_Controller {

/**
  * -----------------------------------------------------------------------
  * Class variables - public, private, protected and static.
  * -----------------------------------------------------------------------
  */


  // ----------------------------------------------------------------------

/**
  *  __construct
  *
  * Class Constructor PHP 5+
  *
  * @access public
  * @return void
  */
  public function __construct()
  {
   parent::__construct();

}

  // ----------------------------------------------------------------------

/**
  * Index Page for this controller.
  *
  */
public function index()
{

}

}

// ------------------------------------------------------------------------
/* End of file Base_Controller.php */
/* Location: ./application/core/MY_Controller.php */

Now extend your other controllers from this Base_Controller

You can create static variables that will retain there value.

A type of Registry Pattern class

Save as ./application/libraries/Property.php

Code:

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

public function clear()

}

/* End of file Property.php */

Either way you will need to save and restore the variable form your database.
