authorization

[eluser]Unknown[/eluser]
Hello,

Am quite new to this. I'm making a page with three different type of users. admin, customer and sales.

I made a model Login:

Code:

<?php
class Login extends model{
    
    function Login(){
        
        parent::Model();
        
    }
    
    function check($type_of_page){
        $this->load->library('session');
        $user_type= $this->session->userdata('user_type');
        
       if($user_type==$type_of_page){
        
        $session_id= $this->session->userdata('session_id');
        
        $this->db->where('session_id', $session_id);
        $this->db->from('ci_sessions');
        $number_of_results= $this->db->count_all_results();
        
        if($number_of_results>0 && $this->session->userdata('logged_in')){
           return TRUE;
        
        }
        else {
            
            redirect(login_check_failed);
            
            
            
        }
       }
    }
}
?>

And i want to lock a user to controllers that that type of user is allowed to see by calling
$this-Login->check('user_type') from the controller and redirect to a error page if the user is not allowed to access that page. I autoload the model Login.

Code:

<?php

class Apply extends Controller {

    

      function Apply(){

            parent::Controller();        

        $this->Login->check('admin');

      

        }

        

        function index(){

            //data till menyn    

            $this->load->helper('admin/menu');

            $this->load->helper('admin/apply');

            $data['menu']=getMenu("apply");

            $data['links']=getLinks();

            $this->load->view('/admin/header', $data);

            $this->load->view('/admin/footer');

        

    }
}

I get this error message when trying to run apply

A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /opt/lampp/htdocs/gov/application/controllers/admin/apply.php:175)

Filename: libraries/Session.php

Line Number: 383

Since i run the login->check() from the top the headers should'nt have been sent? What am I missing?
