Codeigniter 3 redirect issue - php

Question

I'm trying to redirect a not logged in user to a login page, using this code inside Codeigniter 3:
if ( !$this->aauth->is_loggedin() OR !$this->aauth->is_allowed("dashboard"))
{
redirect('auth/login', 'refresh');
}
else
{ //show stuff }
The codeigniter is installed on a subfolder called "admin".
I have the controller Auth.php and the method login exists, but still it doesn't work, the only thing I receive is a 404 Not found error
The routs.php file contains:
$route['default_controller'] = 'home';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
$route['admin'] = 'admin/dashboard';
$route['admin/prefs/interfaces/(:any)'] = 'admin/prefs/interfaces/$1';
And the auth controller :
class Auth extends MY_Controller {
function __construct()
{
parent::__construct();
$this->load->library("Aauth");
$this->form_validation->set_error_delimiters($this->config->item('error_start_delimiter', 'ion_auth'), $this->config->item('error_end_delimiter', 'ion_auth'));
$this->lang->load('auth', 'romanian');
}
function index()
{
if ( ! $this->aauth->is_loggedin() )
{
redirect('auth/login', 'refresh');
}
else
{
redirect('/', 'refresh');
}
}
function login()
{
$this->data['success'] = false;
if ($this->input->is_ajax_request()) {
if ($this->aauth->login($this->input->post('identity'), $this->input->post('password'))) {
$this->data['success'] = true;
} else {
$this->data['message'] = 'Utilizator sau parola gresite!';
}
echo json_encode($this->data);
die();
}
if ( ! $this->aauth->is_loggedin())
{
/* Load */
$this->load->config('admin/dp_config');
$this->load->config('common/dp_config');
/* Valid form */
$this->form_validation->set_rules('identity', 'Identity', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
$this->form_validation->set_rules('remember_me', 'Remember Me', 'optional');
/* Data */
$this->data['admin_assets'] = $this->config->item('admin_assets');
$this->data['title'] = $this->config->item('title');
$this->data['title_lg'] = $this->config->item('title_lg');
$this->data['auth_social_network'] = $this->config->item('auth_social_network');
$this->data['forgot_password'] = $this->config->item('forgot_password');
$this->data['new_membership'] = $this->config->item('new_membership');
if ($this->form_validation->run() == TRUE)
{
$remember = (bool) $this->input->post('remember');
//if ($this->ion_auth->login($this->input->post('identity'), $this->input->post('password'), $remember))
if ($this->aauth->login($this->input->post('identity'), $this->input->post('password'), $remember))
{
//if ( ! $this->ion_auth->is_admin())
if ( $this->aauth->is_allowed("dashboard"))
{
$this->session->set_flashdata('message', $this->ion_auth->messages());
redirect('/', 'refresh');
}
else
{
/* Data */
$this->data['message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('message');
/* Load Template */
$this->template->auth_render('auth/choice', $this->data);
}
}
else
{
$this->session->set_flashdata('message', $this->ion_auth->errors());
redirect('auth/login', 'refresh');
}
}
else
{
$this->data['message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('message');
$this->data['identity'] = array(
'name' => 'identity',
'id' => 'identity',
'type' => 'email',
'value' => $this->form_validation->set_value('identity'),
'class' => 'form-control',
'placeholder' => lang('auth_your_email')
);
$this->data['password'] = array(
'name' => 'password',
'id' => 'password',
'type' => 'password',
'class' => 'form-control',
'placeholder' => lang('auth_your_password')
);
/* Load Template */
$this->template->auth_render('auth/login', $this->data);
}
}
else
{
redirect('/', 'refresh');
}
}
function logout($src = NULL)
{
//$logout = $this->ion_auth->logout();
$logout = $this->aauth->logout();
//$this->session->set_flashdata('message', $this->ion_auth->messages());
if ($src == 'admin')
{
redirect('auth/login', 'refresh');
}
else
{
redirect('/', 'refresh');
}
}
}
Could someone point me to the correct way of redirecting to a specific page?

Answer 1

Try
$link = base_url()."auth/login";
header('Location: '.$link);
Instead of redirect. And don't forget to specify base url in codeigniter config
$config['base_url'] = "http://YOU-DOMAIN.com/YOUR-SUBDOMAIN/";
