I have created a web application with Codeigniter, and I have a problem at the url, controller and structure level.
I have the following web structure.
http://projectroot/admin
Then I have several sections like:
http://projectroot/admin/users
http://projectroot/admin/profile
http://projectroot/admin/section_tracking
http://projectroot/admin/section_products
etc...
I'm working with sessions and other libraries
Currently I have everything in a single controller called Admin, but I would like to create independent controllers that would be calling each part of the url.
In Admin I have:
class Admin extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->library('form_validation');
$this->load->library('My_PHPMailer');
$this->load->library('session');
}
public function index(){
if($this->session->userdata('login')){
if($this->session->userdata('urlnow')){
$url = $this->session->userdata('urlnow');
redirect($url);
}else{
redirect('admin/index');
}
}else{
$data = array();
$data['usererror'] = $this->session->flashdata('usererror');
$data['passerror'] = $this->session->flashdata('passerror');
$data['message'] = $this->session->flashdata('message');
$this->load->view('admin/index', $data);
}
}
...
public function users() {
code....
}
public function profile() {
code....
}
public function section_tracking() {
code....
}
public function section_products() {
code....
}
My idea is that the controller folder contains something like this:
admin.php
users.php
profile.php
section_products.php
section_visits.php
Creating independent Admin extends classes (user, profile, section_tracking and section_products) as independent controllers outside of admin, with a structure similar to this:
users.php
class Users extends Admin {
public function __construct() {
parent::__construct();
$this->load->library('form_validation');
$this->load->library('My_PHPMailer');
$this->load->library('session');
}
public function index(){
code here...
}
}
profile.php
class Profile extends Admin {
public function __construct() {
parent::__construct();
$this->load->library('form_validation');
$this->load->library('My_PHPMailer');
$this->load->library('session');
}
public function index(){
code here...
}
}
How can I do it? I don't want to use HMVC, I just want with MVC native.
Thank you
In your application/controllers/admin folder...Make following files
Admin.php
Users.php
Profile.php
Section_products.php
Section_visits.php
Then make call to each files like this...
http://projectroot/admin/users
http://projectroot/admin/profile
http://projectroot/admin/section_tracking
http://projectroot/admin/section_products
etc...
And here you want to extends admin controller.so make Admin_controller.php by extending CI_Controller in application/core. Your `Admin' controller must be like this....
class Admin_controller extends CI_Controller
{
function __construct()
{
parent::__construct();
}
}
Then always extends Admin_controller.CI_Controller automatically extended.
I have an app using CI 1.7.2.
In controller i have $data['title'] = 'Sample Title';
In view
<?php echo $title; ?>
Should print it.
But not working.
I have another app with latest CI, in that passing like this works fine.
Anybody know reason for this strange issue?
You should pass the data to view like,
$this->load->view('view_file', $data);
There is another way to pass data to view use the library parser
class home extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->helper(array('form', 'url', 'date'));
$this->load->library('form_validation');
$this->load->library('session');
$this->load->library('parser');
}
public function index() {
$this->sssssssss();
}
function sssssssss($data = '') {
$header = $this->parser->parse('interface', array(), TRUE);
$data['interface'] = $header;
//bind all together and parse to template view
$this->parser->parse('template_view', $data);
}
}
I'm not CI programmer, just trying to learn it. Maybe this is wrong approach, please advice.
my controller(not in sub directory) :
class Users extends CI_Controller {
function __construct() {
parent::__construct();
}
public function index($msg = NULL) {
$this->load->helper(array('form'));
$data['msg'] = $msg;
$this->load->view('user/login' , $data);
}
public function process_logout() {
$this->session->sess_destroy();
redirect(base_url());
}
}
And a route for login :
$route['user/login'] = 'users/index';
Problem is when I wanna logout, it shows me 404 because I do not have it in my route :
$route['user/process_logout'] = 'users/process_logout';
and in my view I put logout
When I add that, it works, and that is stuppid to add a route for everything. What I'm I doing wrong, please advice.
Thank you
Don't know why you are trying to implement login feature in index() function. However since you said you are learning CI I'm telling something about _remap() function.
Before that. You can try the following routing:
$route['user/:any'] = 'users/$1';
$route['user/login'] = 'users/index';
If you want to take value immediately after controller segment you need to use _remap() function and this function may be solve your routing problem, i mean you don't need to set routing. Lets implement your code controller 'users' using _remap() function.
class Users extends CI_Controller {
private $sections = array('login', 'logout');
function __construct() {
parent::__construct();
}
public function _remap($method)
{
$section = $this->uri->segment(2);
if(in_array($section, $this->sections))
call_user_func_array(array($this, '_'.$section), array());
else show_404(); // Showing 404 error
}
private function _login()
{
$msg = $this->uri->segment(3);
$this->load->helper(array('form'));
$data['msg'] = $msg;
$this->load->view('user/login' , $data);
}
public function _logout() {
$this->session->sess_destroy();
redirect(base_url());
}
}
I have the below code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Login extends MY_Controller
{
function __construct()
{
parent::__construct();
$this->load->model('users/user_model');
$this->load->library('form_validation');
}
function _load_login_page()
{
$this->load->model('sysconfig/sysconfig_model');
$a = $this->sysconfig_model->get_sysconfig();
$row = $a[0];
$this->lang->load('klas',$row->sysconfig_language);
$data['sys_name'] = $row->sysconfig_system_name;
$data['template_name'] = $row->systemplate_name;
$data['css_script'] = base_url().'assets/'.$row->systemplate_name;
if($row->sysconfig_maintenance === 'Y')
{
$this->load->view('sysconfig/maintenance',$data);
}
else {
$this->load->view('login',$data);
}
}
function index()
{
$this->form_validation->set_rules('username', 'Username', 'trim|required|max_length[12]|xss_clean|callback_check_auth');
$this->form_validation->set_rules('password','Password','trim|required');
if($this->form_validation->run($this) == FALSE)
{
$this->_load_login_page();
} else {
redirect('welcome','refresh');
}
}
function check_auth()
{
if($this->user_model->authentication())
{
return TRUE;
}
$this->form_validation->set_message('check_auth',$this->lang->line('invalid_username'));
return FALSE;
}
?>
user_model.php
<?php
class User_Model extends CI_Model
{
function authentication()
{
$this->db->where('useracc_id', $this->input->post('username'));
$this->db->where('useracc_password', md5($this->input->post('password')));
$q = $this->db->get('base_useracc');
if($q->num_rows() == 1)
{
$session_data = array('isUserLogged'=>TRUE);
$this->session->set_userdata($session_data);
return TRUE;
}
}
?>
From here we can see if the user didn't fill the username and password fields, it will show the error and everything works as expected. The problem is, if the user provides an invalid username or password, the error message won't show.
for the information, I already put $lang['invalid_username'] = 'Invalid username or password'; on the language file.
I am doing this using the HMVC technique. Please help me.
You don't seem to be passing any data to your callback function. Callback functions expect the value of the input field to be passed as a parameter. I don't think you can make this work as a form validation callback be because the authentication method presumably needs to know both the password and the username. At present you're not passing any data into your check_auth method or indeed onwards to your user_model->authentication() method. That is why form_validation is ignoring it.
Rather than calling check_auth as a callback, why not run the form_validation first (this is really what it's for - checking the data is correct and sanitised) and then pass the values from your form to your check_auth function as part of an if statement. You will not be able to use the form_validation set_message method to display errors but I think this is a cleaner approach.
To summarise, use the form_validation to check the data you are receiving is ok and display relevant messages if it is not. Authenticating a user based on that information is a separate procedure that I don't think belongs with validation. Do you see the difference?
from the HMVC wiki page :
When using form validation with MX you will need to extend the CI_Form_validation class as shown below, before assigning the current controller as the $CI variable to the form_validation library. This will allow your callback methods to function properly. (This has been discussed on the CI forums also). ie:
<?php
/** application/libraries/MY_Form_validation **/
class MY_Form_validation extends CI_Form_validation
{
public $CI;
}
<?php
class Xyz extends MX_Controller
{
function __construct()
{
parent::__construct();
$this->load->library('form_validation');
$this->form_validation->CI =& $this;
}
}
im trying to create a new lib which will auto load each time a controller is loaded and authenticate to see if a user is logged in
I’m auto loading the script and its loading fine how-ever it doesn’t seam to authenticate
My Lib
class Authentication {
var $CI;
function Authenication() {
$this->CI =& get_instance();
$this->CI->load->library('session');
$is_logged_in = $this->CI->session->userdata('is_logged_in');
if(!isset($is_logged_in) || $is_logged_in != true)
{
echo 'You don\'t have permission to access this page. Login';
die();
}
}
}
Any suggestions are greatly appreciated
I see what you are trying to do and I would suggest a different approach.
Create MY_Controller and put it in the core folder. Here is a basic representation of what should be in that file.
class Public_Controller extends CI_Controller
{
// The data array holds all of the information to be displayed in views
public $data = array();
function __construct()
{
parent::__construct();
// Authentication library handles sessions and authentication, etc...
$this->load->library('Authentication');
$this->data['account']['is_logged_in'] = $this->authenication->is_logged_in();
}
}
class Auth_Controller extends Public_Controller
{
function __construct()
{
parent::__construct();
if ( !$this->data['account']['is_logged_in'] )
{
redirect('user/login', 'location');
}
}
}
If you do it this way then for controllers that require authentication you can just extend Auth_Controller otherwise extend Public_Controller.
