I want to create a page, which I will be able to browse like this: /page/5.
I have created a page.php controller and I can view this page, here is its content:
class Page extends CI_Controller {
public function __construct()
{
parent::__construct();
}
public function index()
{
$this->load->view('template/header');
$id = $this->uri->segment(2);
$this->load->view('template/middle', array('id' => $id));
$this->load->view('template/footer');
}
}
The problem is that I cant reach the page number from the uri.
To be clear:
This is reachable: index.php/page.
But at this url, I'm getting the 404: index.php/page/5
I know I can make another controller function to view the page like this /index.php/page/id/5, but I want it be be accessable via the index function.
Is that possible?
CodeIgniter doesn't know whether you're looking for 5() or index(5)
To fix this, Try setting up a custom route in config/routes.php:
$route['page/(:num)'] = 'page/index/$1';
Also, In your index function:
public function index($id)
{
$this->load->view('template/header');
$this->load->view('template/middle', array('id' => $id));
$this->load->view('template/footer');
}

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';
Please explain steps how to calculate page views in codeigniter.
Is there any instruction on how to do this.
by using following method:
$this->input->ip_address();
How to Write $this->input->ip_address(); in Below Controller:
Controller Page
class About extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->helper('array');
$this->load->model('about_model');
}
public function index() {
$data = array(
'page_title' => 'About',
'page_name' => 'site/aboutus/about',
'about' => $this->about_model->list_all(),
);
$this->load->view('site/template', $data);
}
}
?>
Model Page:
class About_model extends CI_Model {
function __construct() {
parent::__construct();
}
public function list_all() {
return $this->db->get('about')->result_array();
}
}
$this->input->ip_address() to take the user's ip address in the controller
In the database you save the ip, the time the user first visited the site and a counter
Get the counter: $this->db->select_sum("counter")->get("views_table"); and process the result.
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 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());
}
}
