I create simple library called Xauth.php to check if user already login or not:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Xauth
{
protected $ci;
public function __construct()
{
$this->ci =& get_instance();
}
public function is_logged_in()
{
if ($this->ci->session->userdata('is_logged_in'))
{
return true;
}
return false;
}
}
I put that library in my Admin_Controller, so whatever controller extended with Admin_Controller will be checked first, if the session data is empty they will be redirect to login page. And this is my Admin_Controller.php:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Admin_Controller extends MY_Controller {
public function __construct()
{
$this->load->library('Xauth');
if ($this->Xauth->is_logged_in() == false) {
redirect('auth');
}
}
}
But I got an errors, it says:
Message: Undefined property: Dashboard::$Xauth
Where is my fault?
You must use your class with lowercase letters :
$this->xauth->is_logged_in()

I'm working on a calendar planning provided by [easyappointments][1] but now I'm stuck on this error by yesterday. In the main page users.php I've added the following:
<?php
require_once("application/models/impostazioni_model.php");
$this->load->model('impostazioni_model');
$this->impostazioni_model->load_colours();
?>
the require_once find correctly the file impostazioni_model.php but when I enter in the page users.php I see this error:
Fatal error: Call to a member function load_colours() on a non-object
on this line: $this->impostazioni_model->load_colours();
in the class impostazioni_model.php I've this content:
<?php if ( ! defined('BASEPATH')) exit('Direct execution not allowed.');
class Impostazioni_Model extends CI_Model
{
public function __construct()
{
parent::__construct();
}
public function load_colours()
{
echo "print";
}
}
?>
I've followed the codeigniter documentation, in particular the class model must be in capital letter so I don't know what I'm wrong. Someone could help me out?
In Controller
Path - application/controllers
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Admin extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('impostazioni_model'); //this will show "Print" word on browser.
}
function index() {
$this->impostazioni_model->load_colours();
}
}
In Model
Path - application/model
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Impostazioni_model extends CI_Model {
function __construct() {
parent::__construct();
}
function load_colours() {
echo "print";
}
}
I have placed this controller on application/core, called MY_base.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Base_Controller extends CI_Controller {
public function __construct(){
parent::__construct();
}
function set_spaces($post_array, $primary_key){
$post_array['nombre']=str_replace(" ", "_", $post_array['nombre']);
return $post_array;
}
}
?>
and this controller on the controllers folder
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Clase extends Base_Controller {
function __construct(){
parent::__construct();
$this->load->library('grocery_CRUD');
}
function index(){
if($this->session->userdata('logged_in')){
$this->grocery_crud->set_table('clase');
$this->grocery_crud->set_subject('Clase');
$this->grocery_crud->required_fields('nombre');
$this->grocery_crud->unset_columns('id');
$this->grocery_crud->unset_print();
$this->grocery_crud->unset_export();
$this->grocery_crud->unset_add();
$this->grocery_crud->callback_before_update(array($this,'set_spaces'));
//$this->grocery_crud->set_theme('datatables');
$output = $this->grocery_crud->render();
//$this->load->view('header', $data);
$this->load->view('header2.php',$output);
$this->load->view('clase_view', $output);
}
else{
redirect('login', 'refresh');
}
}
}
?>
I think I've followed documentation's instructions correctly but I get this error
Fatal error: Class 'Base_Controller' not found in C:\xampp\htdocs\esi3d\application\controllers\clase.php on line 3
It looks like is looking for base_controler on controllers folder not in core folder.
Place your MY_base.php also in controllers folder
For the life of me I cannot understand why I am receiving errors with my install of CodeIgniter and this current MVC set up.
The error I see is
Fatal error: Call to undefined method Login::users_model() in /var/www/application/controllers/login.php on line 17
Controller application/controllers/login.php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Login extends CI_Controller {
public function __construct()
{
parent::__construct();
}
public function index()
{
$data = '';
$this->load->model('users_model');
$data['testing'] = $this->users_model()->test_user();
$this->load->view('home',$data);
}
}
Model application/models/users_model.php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Users_model extends CI_Model {
function __construct()
{
// Call the Model constructor
parent::__construct();
}
function test_user() {
return 'Test User #1';
}
}
View application/views/home.php
echo $testing;
No need for function bracket with model name
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Login extends CI_Controller {
public function __construct()
{
parent::__construct();
}
public function index()
{
$data = '';
$this->load->model('users_model');
$data['testing'] = $this->users_model->test_user();
$this->load->view('home',$data);
}
}
Replace $data['testing'] = $this->users_model()->test_user(); with $data['testing'] = $this->users_model->test_user(); in your controller.
Simply load your model inside the constructor
public function __construct()
{
parent::__construct();
$this->load->model('users_model');
}
Then simply call the relevant functions inside any controller functions like this.
public function index()
{
$data = '';
$data['testing'] = $this-> users_model-> test_user();
$this->load->view('home',$data);
}
I have been working on a session validation for my login to make sure that a user is logged in to view pages. I keep getting this error:
Fatal error: Class 'MY_Staffcontroller' not found in /usr/local/var/www/CodeTest
/ci/application/controllers/staff_c.php on line 3
My staff_c page looks like so :
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Staff_c extends MY_Staffcontroller {
function homepage()
{
$data['main_content'] = 'homepage_view';
$this->load->view('includes/template', $data);
}
}
I have been reading same questions all over the place and they say the same thing pretty much...
Is your controller located in application/core?
Well yes it is. I can't seem to get passed this hump!
This is the code within My_Staffcontroller.php:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_staffcontroller extends CI_Controller {
function __construct()
{
parent::__construct();
$loggedin = $this->session->userdata('loggedin');
if(!isset($loggedin) || $loggedin != TRUE);
{
die($this->load->view('denied'));
}
}
}
I know this is user error as this is only my second day with CodeIgniter but I can't seem to find proper workaround for this?
I have tried this tutorial and still nothing and also this
Even following this video has me stuck on the session part.
And I just can not get this to work.
Remember Linux is case-sensative whereas Windows is case-insensative.
place you're MY_Staffcontroller inside application/core/MY_Controller.php file
Your MY_Controller.php file should look like this (minus all you're other functions, this is a minimal example)
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Controller extends CI_Controller
{
public function __construct()
{
parent::__construct();
}
}
class MY_Staffcontroller extends MY_Controller
{
public function __construct()
{
parent::__construct();
}
public function sayHello()
{
echo "Hello, I am a function within MY_Staffcontroller.php";
}
}
Example
This will be located in /application/controllers directory
Basically any protected and public functions located in either MY_Controller OR MY_Staffcontroller will be accessible from derived controllers that extend the extended controller. In this case it would be MY_Staffcontroller
class Public_Staff_Controller extends MY_Staffcontroller
{
public function __construct()
{
parent::__construct();
}
public function index()
{
$this->sayHello();
}
}
/* end of file /application/core/MY_Controller.php */
Is there a way of preventing session class to set cookie and adding a record in database when calling it from the command line?
The simplest way I think would be to extend the Session class like this :
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Session extends CI_Session
{
public function __construct()
{
$CI = get_instance();
if ($CI->input->is_cli_request())
{
return;
}
parent::__construct();
}
}
Just place it in the application/libraries folder. And with a controller like this :
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Welcome extends CI_Controller
{
public function no_cli_session()
{
$this->load->library('session');
$this->session->set_userdata('logged', 'yes');
}
}
When you call the function from your browser the session is set and when you call it from cli it is not.
