I have one controller named home.php in which a function named podetails is there. I want to call this function in another controller user.php.
Is it possible to do so? I have read about HMVC in CI, but I want to know is it possible to do without using hmvc?

7So you are using common code for both controllers. Then you make it as library function / or helper function. You can call anywhere in project.Kumar V– Kumar V2014-01-14 10:07:36 +00:00Commented Jan 14, 2014 at 10:07

To extend controller please either follow this tutorial or see some code below.
differences between private/public/protected
make a file in folder /application/core/ named MY_Controller.php
Within that file have some code like
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Controller extends CI_Controller {
protected $data = Array(); //protected variables goes here its declaration
function __construct() {
parent::__construct();
$this->output->enable_profiler(FALSE); // I keep this here so I dont have to manualy edit each controller to see profiler or not
$this->load->model('some_model'); //this can be also done in autoload...
//load helpers and everything here like form_helper etc
}
protected function protectedOne() {
}
public function publicOne() {
}
private function _privateOne() {
}
protected function render($view_file) {
$this->load->view('header_view');
if ($this->_is_admin()) $this->load->view('admin_menu_view');
$this->load->view($view_file . '_view', $this->data); //note all my view files are named <name>_view.php
$this->load->view('footer_view');
}
private function _isAdmin() {
return TRUE;
}
}
and now in any of yours existing controllers just edit 1st or 2nd line where
class <controller_name> extends MY_Controller {
and you are done
also note that all your variables that are meant to be used in view are in this variable (array) $this->data
example of some controller that is extended by MY_Controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class About extends MY_Controller {
public function __construct() {
parent::__construct();
}
public function index() {
$this->data['today'] = date('Y-m-d'); //in view it will be $today;
$this->render('page/about_us'); //calling common function declared in MY_Controller
}
}

write the podetails() as a function within a helper file.
then load that helper in both of the controllers.
in the controller you just call podetails()
Suppose:
--controller 1--
function podetails()
{
podetails(); // will call function in helper ;
}
--controller 2--
function podetails()
{
podetails(); // will call function in helper ;
}
