Where is the best place to start my session? session_start()

[eluser]Swammy[/eluser]
Basically every page on my site can be accessed by a logged in user. So how do I globally make sure the session is starting on every page refresh?

Code:

session_start()

Just auto-load the session library( for CI 2.X ) or the session driver( for CI 3.X )

or if you wish load the session library/driver on your controller constructor

You can auto load the session. The location of the file is can be found in "application/config/autoload.php"

I would create a MY_Controller,php located in the core that extends the CI_Controller. Then I would create an Admin_Controller.php located in libraries that extends MY_Controller. For example, see this below:

Code:

<?php
class Admin_Controller extends MY_Controller
{

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

  $this->load->library('api');
  $this->load->model('your_model');

  if ( ! $this->uri->segment(3, 0))
  {
   $this->is_logged_in();
  }
  
  $this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate");

}
  
  function is_logged_in()
{
  $is_logged_in = $this->session->userdata('is_logged_in');

  if(!isset($is_logged_in) || $is_logged_in != true)
  {
   echo 'You don\'t have permission to access this page.';
   echo anchor('login/index', 'Login');
   exit();  
   //$this->load->view('login_form');
  }  
}
}

Then just extend whatever class to the Admin_Controller

And to use the is_logged_in() function example:

Code:

function login_user()
{  
  $this->load->model('Membership_model');          
  $query = $this->Membership_model->validate();        
  //pass user's id(id created in model) in the login
  $id = $query['id'];
  // if the user's credentials validated...
  if($query)      
  {

   $data = array(
    'user_id' => $id,          
    'username' => $this->input->post('username'),
    //add value to session      
    'is_logged_in' => true            
   );
   //set session equal to $data array
   $this->session->set_userdata($data);
   //redirect to members area if session is true        
   redirect('site/members_area', 'refresh');          
  }

Okay thanks guys. So if I am autoloading sessions I should be fine on a global level? Great.

If you are using custom sessions, you should start it in index.php file.

But yes, CodeIgniter sessions work very well, and allow you to do some cool stuff (automated flashdata!)
