In Codeigniter 3.0, How to load my custom library for all controllers except only login controller

Question

I try to search on google for this question. I really want to load my MY_Login Library to all my controllers for check session. (not one by one) but except only login controller i don't want to load in.

Library

class MY_Login {

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

        // call with constructor.
        $this->isLogin();
    }

    function isLogin() {
         //source code
    }  
}

Any comments would be appreciated :)

Answer 1

You should use core MY_Controller on controllers like dashboard etc

application > core > MY_Controller.php

class MY_Controller extends CI_Controller {

public function __construct() {
   parent::__construct();
   $this->load->library('login');
}

}

Controller

class Dashboard extends MY_Controller {

  public function index() {

  }

}

http://www.codeigniter.com/user_guide/general/creating_libraries.html Library example

class Login {
  public function __construct() {
    $this->CI =& get_instance();

    $this->CI->load->library('session');

    if ($this->CI->session->userdata('is_logged') == TRUE) {

    } else {

     $this->logout();

    }
  }

  public function login
      // How to use session in library example.

     $this->CI->session->set_userdata(array('is_logged'=> true)); 
  }


  public function logout() {
    $this->CI->session_unset_userdata('is_logged');
  }


 }

I would suggest reading more of the user guide first. http://www.codeigniter.com/user_guide/index.html
