I am trying to make a Codeigniter 3 application to authenticate to a CAS server.
I installed the phpcas package with composer but I cant find any details or examples on how to do this. I want the access to this application to be only from authentication users.
I believe that I have to edit a config file but I cant find any to write down the cas server url, etc. Also, in the controller of the page, I have to call somehow the library but I need some example for that.
So the main question is how can i get to use phpcas inside my controller methods amd how to configure it?
I created a controller and have inside:
?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class AuthController extends CI_Controller {
public function actionLogin()
{
$this->module->casService->forceAuthentication();
$username = $this->module->casService->getUsername();
$this->module->casService->getAttribute('mail')
$this->module->casService->getAttribute('title')=='TEACHER';
//$auth->assign($casRole, $user->id);
}
public function actionLogout()
{
$this->module->casService->logout(Url::home(true));
// In case the logout fails (not authenticated)
return $this->redirect(Url::home(true));
}
}
I place to the controller file the line:
require_once(APPPATH . '/../vendor/autoload.php');
and I init with:
$phpCAS = new phpCAS;
phpCAS::client(CAS_VERSION_2_0, 'sso-test.sch.gr', 443, '', false);

I have used several codes for restricting direct access of controller page from url, but its not happening.
The below code in controller page is not preventing from direct url access. Is there any proper way to prevent from direct access from url?
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Cont extends CI_Controller
{
public function __construct()
{
parent ::__construct();
$this->load->model('test');
}
public function handle($function){
if($function=='abcd'){
$this->load->view('testpage');
}
}
}
You can use HTTP_REFERER which holds the information(address) about the page that referred you to the current page, if it's empty you can redirect it to your 404 page. Also, you should always check for $_SESSION and redirect if not set.
if( !isset($_SERVER['HTTP_REFERER'])) {
$this->load->helper('url');
redirect('/page404');
}
Alternatively, you can also use HTTP_X_FORWARDED_FOR, but it won't help you in AJAX request. Read more about it here and here.
You can use _remap() function inside your Controller, where we can define where to route the method.
The following code blocks all method call to that controller.
function _remap($method)
{
return false;
}
See the DOC here
From documentation
For the best security, both the system and any application folders should be placed above web root so that they are not directly accessible via a browser. By default, .htaccess files are included in each folder to help prevent direct access, but it is best to remove them from public access entirely in case the web server configuration changes or doesn’t abide by the .htaccess.
If you want to prevent direct access to specific methods then you can try
public function _handle(){ //adding _ before the method name
}
Or
private function handle(){ //private functions cannot access by url
}
I have this error when i am trying to access a website from wamp, it is done in codeigniter.
Error:
localhost is currently unable to handle this request. HTTP ERROR 500
homeindex controller
<?php

$this->load->helper('html');
$this->load->helper('form','url','file');
$this->load->library('session','upload');
}
public function index()
{
//$this->load->view('coming_soon');
$this->load->view('homeIndex');
}

I am able to access other website which are not done using any frameworks.
This website is done using codeigniter. I am not able to access the website.
Can anyone tell me what is the problem?
Multiple loads with one call are done using an array:
$this->load->helper(array('form','url','file'));
$this->load->library(array('session','upload'));
https://www.codeigniter.com/user_guide/libraries/loader.html#CI_Loader::helper
if that doesn't work turn on error reporting (switch to development mode in index.php) and see what the actual error is. 500 error can be many things...
i need to access the admin controller in codeigniter using the url mywebsite.com/admin
but it returns "The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again" error
my code is
routes.php
$route['admin'] = 'admin/adminmain';
adminmain.php (admincontroller)
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Adminmain extends CI_Controller {
public function index()
{
$this->load->view('admin/adminhome');
}
}
In Codeigniter 3 or above controllers name should be capitalized.
The controller file name should be Adminmain.php
controller file name should be Adminmain.php and try to define route like: $route['admin'] = 'admin/Adminmain'; and also check r u defining admin folder under controller folder
I have downloaded the ci-hmvc-master and setup it.
Now in that I have created a one hook at pre_controller hook point.
In that hook, I have created one function that print the current class and method.
my code looks like this:
<?php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Authentication{
protected $CI;
public function __construct() {
$this->CI = & get_instance();
}
public function is_loggedin(){
$class = $this->CI->router->fetch_class();
echo $class;
}
}
This code is working fine. I got the class name.
Now my issue is that when I use this same code in HMVC which is created from normal MVC (replacing some of the folders and files) then I got the error like:
Call to a member function fetch_class() on null
Means The pre_controller hook executes before the super object has been fully constructed, so get_instance() can't work.
So, why it is working in HMVC extension which I have downloaded and why it is
not working in simple HMVC which is created from MVC.
Is there any configuration is missing?
I am trying to build a web application with codeigniter. I have installed Ion Auth as my authentication model.
The default Auth.php controller authenticates the user and sets up the session.
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Auth extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->library('ion_auth');
$this->load->library('session');
$this->load->library('form_validation');
$this->load->helper('url');
$data['title']="Login Page";
$this->load->view("view_site_header",$data);
// Load MongoDB library instead of native db driver if required
$this->config->item('use_mongodb', 'ion_auth') ?
$this->load->library('mongo_db') :
$this->load->database();
$this->form_validation->set_error_delimiters($this->config->item('error_start_delimiter', 'ion_auth'), $this->config->item('error_end_delimiter', 'ion_auth'));
}
//redirect if needed, otherwise display the user list
function index()
{
// if not logged in - go to home page
if (!$this->ion_auth->logged_in())
{
//redirect them to the login page
redirect('auth/login', 'refresh');
}
// if user is an admin go to this page
elseif ($this->ion_auth->is_admin())
{
// if an admin, go to admin area
//set the flash data error message if there is one
$this->data['message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('message');
//list the users
$this->data['users'] = $this->ion_auth->users()->result();
foreach ($this->data['users'] as $k => $user)
{
$this->data['users'][$k]->groups = $this->ion_auth->get_users_groups($user->id)->result();
}
$this->_render_page('auth/view_users', $this->data);
} else
{
//redirect them to the default home page
$data['title']="IMS Home Page";
$this->load->view("generic/view_site_header",$data);
$this->load->view("generic/view_generic_nav");
$this->load->view("generic/view_content_generic");
$this->load->view("view_site_footer");
}
}
what I want to do is create a new controller for my application logic and leave the auth controller for authentication.
How can I make use of the auth controller to ensure my user is logged in when accessing my new controller? in addition I need the ession information to be available to the new controller.
my new controller, master_data has the following code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Masterdata extends CI_Controller{
function index ()
{
$data['title']="Master Data Home Page";
$this->load->view("master_data/view_master_data_header",$data);
$this->load->view("master_data/view_master_data_nav");
$this->load->view("master_data/view_content_master_data_home");
$this->load->view("master_data/view_master_data_footer");
echo $this->session->userdata('username');
}
}
obviously the echo $this->session->userdata('username'); does not work as the new controller has no knowledge of the auth controller session.
any help appreciated as always.
Kind Regards,
First autoload the ion_auth library.
If u simply want to check if the user is logged-in, just check it in every controller's constructor u load
public function __construct() {
parent::__construct();
if (!$this->ion_auth->logged_in()) {
// redirect to login view
}
}
If u happen to have multiple groups , u can create a new controller inside application/core/MY_controller.This controller will check whether user is logged in.You can extend this base controller to create new controller.A very good explanation on this is given by David john.Check this link .
obviously the echo $this->session->userdata('username'); does not work as the new controller has no knowledge of the auth controller session.
Eh...if the session library is loaded, then yes...the controller calling it will be able to access the session variable $username.
The way we handle this is to create a new controller parent class like MY_Controller in the application/core directory. This class loads common libraries/packages (like session and ion_auth). You could also autoload the libraries and helpers.
Since ion_auth stores all of the user profile data in a session var, all you need (on subsequent, non-authenticated) pages is the session lib to retrieve session data about the logged in user.
You really should check for their auth status though, and fail gracefully:
if (!$this->ion_auth->logged_in()) {
// echo a login link
} else {
// echo session var for username
}
Something like that...
jcorrys approach should work. An alternative approach (which will give your entire application a great deal more flexibility is to use a modular layout - https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc
You will have to do a bit of fiddling to get it to play nicely with ion auth, but following the instructions in this question worked for me: Using Ion Auth as a separate module in the HMVC structure (have a look at the forks of ion auth on git hub - I think someone may have already done it for you)
This approach will allow you to access any method in any controller from anywhere in your application (even from a view if you need to) using this kind of syntax: modules::run('module/controller/method', $params);
This will essentially allow you to develop the existing ion auth controller into a user management controller which you can access from any other controllers you create (nice and dry).
