Is it possible to use $this->load->view('abc') from within a custom class??

Hey all my first post on here and have used Codeigniter a bit in the past so hope I am not being a dumb-ass but here is my query.

I would like to make my controllers cleaner in terms of code by creating custom classes for common methods/functions that I call within them. For instance having an if statement within every controller that checks if a user is logged in could be done on a single line as a method call to a custom class.

So instead of this as a controller...

Code:

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

class Members_only extends CI_Controller {
    
    public function index()
    {    
        if($this->some_class->is_logged_in())
        {
            $this->load->view('welcome_message');
        }
        else
        {
            redirect('authentication/admin');
        }
    }
}

I would rather do this as a controller...

Code:

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

class Members_only extends CI_Controller {
    
    public function index()
    {    
        
        $this->some_class->is_logged_in('welcome_message', 'authentication/admin');
        
        
    }
}

You can see I would like to pass the page names as parameters to my custom classes method, it is within this method that I would then like to load the view but it would seem that Codeigniter does not like the idea of me trying to load a view from within my own class - do I need to extend my class as part of a core Codeigniter object in order to inherit this ability (bearing in mind I have already tried extending my class as part of the CI_Controller and it did not work) or is there something else I need to do??

My custom class looks like so...

Code:

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

class Some_class{
    
    public function __construct($allowed = NULL, $disallowed = NULL)
    {
        $this->allowed = $allowed;
        $this->disallowed = $disallowed;
    }
    
    public function is_logged_in()
    {
        // PUT get_instance() IN THE FUNCTION/METHOD IF USING PHP 4
        // ELSE USE WITHIN THE CONTRUCTOR
        
        $CI =& get_instance();
        $CI->load->library('session');
        
        
        if($CI->session->userdata('is_logged_in'))
        {
            $this->load->view($this->allowed);
        }
        else
        {
            redirect($this->disallowed);
        }
        
    }
}

So essentially is it possible to use $this->load->view('abc') from within a custom class??

No worries - I was being a dumb-ass after all.

All I did was change my custom class to look like so...

Code:

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

class Some_class{
    
    public function is_logged_in($allowed, $disallowed)
    {
        // PUT get_instance() IN THE FUNCTION/METHOD IF USING PHP 4
        // ELSE USE WITHIN THE CONTRUCTOR
        
        $CI =& get_instance();
        $CI->load->library('session');
        
        if($CI->session->userdata('is_logged_in'))
        {
            // Error do something about it
            $CI->load->view($allowed);
        }
        else
        {
            redirect($disallowed);
        }
    }

Now my Controller looks soooo nice and clean...

Code:

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

class Members_only extends CI_Controller {
    
    public function index()  
    {    
        $this->authenticate->is_logged_in('welcome_message', 'authentication/admin');
    }

SWEET!
