How to access a public static variable in a model from a controller in Codeigniter?

Question

Here is the model structure

class Misc_model extends CI_Model {

    public function __construct() {
        parent::__construct();
    }

    public static $type_alphabet        = 'a';
}

I am accessing the variable from a Controller, like this:-

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
require_once('webservice_common.php');
class Webservice_user extends Webservice_common {

    protected $_data = array();

    public function __construct() {
        parent::__construct();
    }

    public function preRegistration(){
        $miscObj = new Misc_model;
        $type = $miscObj::$type_numeric;
    }
}

Is this the right way to do in Codeigniter, or is there some other way? In codeigniter, we load models like this:-

$this->load->model('misc_model');

And for calling a function we write like this:-

$this->misc_model->the_function();

Is there any other specific way (in Codeigniter) to access public static function from a different controller?

Answer 1

Try this

Model:

class Misc_model extends CI_Model {

    public function __construct() {
       parent::__construct();
    }

    public static $type_alphabet = 'a';
}

Controller:

public function preRegistration(){
    $this->load->model('Misc_model');
    $type = Misc_model::type_numeric;
}
