how can i manage url in address bar after posting a form or after loading a page after submission.
Is it possible to manage with routing ?
<?php
public function index(){
$this->load->view('login');
}
public function login_process(){
....... code......
if($login==true){
$this->load->view('dashboard'); // Url is not changing but view is loaded
}else{
$this->load->view('login');
}
}
?>
Hope this will help you :
Use redirect() method from url helper , make sure you load it in controller or in autoload.php
public function login_process()
{
....... code......
if($login === TRUE)
{
redirect('controller_name/dashboard','refresh');
/*$this->load->view('dashboard'); */
}
else
{
redirect('controller_name/index','refresh');
/*$this->load->view('login');*/
}
}

You should create another method called dashboard and you should redirect to it like following
class Example_Controller extends CI_Controller {
public function index(){
$this->load->view('login');
}
public function dashboard(){
$this->load->view('dashboard');
}
public function login_process(){
// Your Code
redirect('Example_Controller/' . (($login==true) ? 'dashboard' : 'index'));
}
}
replace Example_Controller with your controller name.
and add following lines in routes.php
$route['login'] = 'Example_Controller/index';
$route['dashboard'] = 'Example_Controller/dashboard';

I want to redirect to index page having username or other things. Like a branch coordinator when do login , then he redirect to index/{branch_name}.
Please help me to do that.
My Route :
Route::get('/branch' , 'HomeController#index');
Controller :
class HomeController extends Controller
{
public function __construct()
{
$this->middleware('auth:branch');
}
public function index()
{
return view('branch.index');
}
}
In web.php change to :
Route::get('/branch/{branch_name}' , 'HomeController#index');
In controller
public function index($branch_name)
{
//$branch_name will be containg the variable
return view('branch.index');
}
To redirect to above page
return redirect()->route('branch/'.$branch_name);
I don't know how to phrase this question on google so i couldn't find any answers.
In my Views folder, i have templates folder with header,navbar,footer inside.
Whenever i load a view from my controller i would have to do this,
$this->load->view('template/header');
$this->load->view('template/navbar');
$this->load->view('pages/pagename');
$this->load->view('template/footer');
How do i do this with redirect? I don't know why but whenever i see code snippets of successful logins or failures they always use the redirect function instead of load view like the above.
for example:
function __construct() {
parent::__construct();
if($this->ion_auth->logged_in()==FALSE)
{
redirect('pages/login');
}
}
or can i use this and will this still be acceptable?
function __construct() {
parent::__construct();
if($this->ion_auth->logged_in()==FALSE)
{
$this->load->view('template/header');
$this->load->view('template/navbar');
$this->load->view('pages/login');
$this->load->view('template/footer');
}
}
function __construct() {
parent::__construct();
if($this->ion_auth->logged_in()==FALSE)
{
redirect('controller/login');
}
}
in your controller, create a function called login
function login() {
$this->load->view('template/header');
$this->load->view('template/navbar');
$this->load->view('pages/login');
$this->load->view('template/footer');
}
In redirect you need to use controller/method_name
redirect('controllername');
or
redirect('controllername/method');
Rather than construct you can use remap. to redirect if the user is logged or not
REMAP
public function _remap($method, $params = array()){
if(method_exists($this, $method)){
if($this->ion_auth->logged_in()==FALSE){
return call_user_func_array(array($this, $method), $params); //home page
}
return call_user_func_array(array($this, 'login'), $params); //if not logged in
}
show_404();
}
LOGIN
public function login() {
$this->load->view('template/header');
$this->load->view('template/navbar');
$this->load->view('pages/login');
$this->load->view('template/footer');
}
I am new to CodeIgniter framework. I am using 2.1.4 version. I designed a simple login form, with a javascript validation, and the home page of a site. Can you please help me to understand how to declare session , and how to destroy the session on clicking signout link.
controller file of login page ( to load the view page login.php ):-
class Login extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->helper('url');
}
function index(){
$this->load->view('login');
}
function success() {
redirect ('home');
}
}
The controller file home.php for the view home.php
class Home extends CI_Controller {
// local constructor will be overriding the one in the parent controller class
// for using a constructor in any of my Controllers
function __construct() {
parent::__construct();
}
public function index()
{
$this->load->view('home');
}
}
I have designed the view page home.php, and gave the signout link:-
<div class="logout">Signout</div>
For initializing the session, i need to know, what all constructor changes/ config changes need, and the method of session destoy.
To start session library, Go to application/config/config.php and change the below line:
$autoload['libraries'] = array('session');
It would be better if you start your session in the autoload.php. To destroy session you would use :
$this->session->sess_destroy();
To set session :
$newdata = array(
'username' => 'johndoe',
'email' => 'johndoe#some-site.com',
'logged_in' => TRUE
);
$this->session->set_userdata($newdata);
here is an controller... first of all u need to declare a session so that you have two choice to declare one is Go to application/config/config.php change the code as
$autoload['libraries'] = array('session');
and follow this following method (controller)
class Login extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->library('session');
}
function index(){
$this->load->view('login');
}
function success() {
$user=$this->input->post('user');
$psw=$this->input->post('pswd');
$this->load->model('validation');
$result=$this->validation->useraccess($user,$psw);
if($result)
{
$this->session->set_userdata('username', $user); //setting session
redirect ('home');
}
else
{
$this->index();
}
}
function logout()
{
$this->session->unset_userdata('username');
redirect('login','refresh');
}
}
this is model where validation done
Class Validation extends CI_Model{
function __construct(){
parent::__construct();
}
function useraccess($user,$pswd)
{
$query = $this->db->query("select * from user where username='$user' AND password='$pswd'");
foreach ($query->result_array() as $row)
{
if($row['username']==$user AND $row['password']==$pswd)
{
return true;
}
else
{
return false;
}
}
}
}
here is a view
login page
create 2 text box and 1 submit button and declare form action as
localhost/index.php/login/success
for logut
localhost/index.php/login/logout
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 am using HMVC with CodeIgniter.
I have this in my testmodule controller:
public function index()
{
$this->view_data['main_content'] = 'frontpage';
$this->load->view('template', $this->view_data);
}
And this in my view template.php of that controller that is loaded by this controller:
<?php
$this->load->view('includes/header');
$this->load->view($main_content);
$this->load->view('includes/footer');
?>
but, when I var_dump($main_content) in the view and die() it shows null instead of frontpage
How, come? I don't get it at all.
If you want to use $this->view_data you have to declare $view_data as a property first (at the top of your controller):
class TestModule extends CI_Controller
{
public $view_data = array();
public function index()
{
// Now you can use $this->view_data in this function:
$this->view_data['main_content'] = 'frontpage';
$this->load->view('template', $this->view_data);
}
}
