My home page url looks like this
http://localhost/mediabox/home/box/12
I have a link of language on home page when a user clicks on that link i am sending that language id as query string , the page reloads and the url converts to
http://localhost/mediabox/home/box/?bid=12&ln=2
I want to reload the page with the new language but don't want to change my url i-e I want my URL to be
http://localhost/mediabox/home/box/12

How it is possible please me some gud ideas
Thanks

created a simple page of session, Even after logout from the page i'm still able to access the login page.
I have also destroyed all the session but still can't find any solution.
view - flashdata_home.php
<form action='add' method='post'>
<input type ='text' name='value'/>
<input type='submit' value='Enter ' />
</form>
Controller - FlashData_Controller.php
<?php
class FlashData_Controller Extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->library('session');
$this->load->helper('url');
}
public function index(){
$this->load->view('flashdata_home');
}
public function add(){
// adding flash data
//$this->session->set_flashdata('item','This is me');
$this->session->set_userdata('Name',$this->input->post('value'));
//redirect to home page
// redirect('flashdata');
if($this->session->has_userdata('Name')){
$data = array('value' => $this->session->Name);
$this->load->view('adminflashdata_home',$data);
}
else
{
$this->load->view('flashdata_home');
}
}
public function logout(){
$this->session->unset_userdata('Name');
$this->session->sess_destroy('Name');
$this->load->view('flashdata_home');
}
}
view - adminflashdata_home.php
<?php
echo $value;
<li>Logout</li>
?>
Unsettling the session in CI is very simple and it looks like this.
In your Code you have unset the data but you have to unset the variable as i did.
For Single Data:
$this->session->unset_userdata('some_name');
For Array of Datas:
$array_items = array('username' => '', 'email' => '');
$this->session->unset_userdata($array_items);
For destroy the session:
$this->session->sess_destroy();
I think your problem is, though we destroy session we can still access the page that should be loaded only if the user in logged in.
For example, when user log in with correct credentials the url should look like this: localhost/app/controller/function (just for instance). And later when the user log out you will redirect back to login page. But if we type localhost/app/controller/function in url or if we click back button in browser, the browser will load the page !!! I consider your stated problem is same like this.
For this problem I always use a solution in every function of controller. Like;
class MainController extends CI_Controller {
function test {
$user_name = $this->session->userdata('user_name');
if(isset($user_name)) {
//the actual function code goes here
}
else {
//redirect to the login function
}
}
}
I hope this helped some one.. cheers..
I have an home controller who control the homepage (that is a simple landing page with no user interaction or dynamic data):
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Home extends CI_Controller {
private $data;
protected $pagedata;
function __construct()
{
parent::__construct();
if ($this->session->userdata('is_logged_in') == true) {
$this->data['nav'] = 'auth/template/homelogin_nav';
}
$this->pagedata['title'] = 'La Giumenta Bardata Cosplay & Props';
}
/**
* Index Page.
*
**/
public function index()
{
$this->load->view('template/header', $this->pagedata);
$this->load->view("template/nav", $this->data);
$this->load->view('section_header');
$this->load->view('section_about');
$this->load->view('section_services');
$this->load->view('section_portfolio');
$this->load->view('section_social');
$this->load->view('template/footer');
}
}
So basicly, if user is log in I load a certain view that correspond to a nav, if not it's loaded the normal menu.
Now, the two navs are different just for one link (one nav's view has a link to the login page and the other one has a link to the user dashboard).
I also try this:
$this->load->view($this->data);
but of course is illegal and it doesn't work.
The problem starts because I have to check for the session in the costruct and not inside the function index() or I can't check it.
Why don't you check for session inside of view?
Make one navigation and if user is logged in show dashboard, if not show login button in navigation.
Navigation view:
<ul>
<li> <?php echo anchor('home','Home'); ?> <li>
<?php if($this->session->userdata('is_logged_in')== true){
echo "<li>".anchor('dashboard','dashboard')."</li>";
echo "<li>".anchor('logout','logout')."</li>";
}else
echo "<li>".anchor('login','login')."</li>"; ?>
</ul>
I have some experience with php, but I just recently started learning Codeigniter. I used to have a website with a fixed navigation pane and sidebar, but the main section of the site loaded dynamically based on a Get variable. It was basically
include head.php
include navbar.php
include sidebar.php
include the page requested from the get variable (home, about, contact, etc.)
include footer.php
I liked this because the entire site did not have to reload when the user navigated from page to page.
I can't figure out how do this with Codeiginiter. Should I be using a controller for each page or one controller with a function for each page? Do anyone know of a good tutorial that does something similar? All the tutorials I've seen reload the entire site for every page.
Edit: Essentially I want to do this but with Codeigniter
Since it looks like you want relatively static content, but loaded dynamically you can do with one controller and (maybe) one method in the controller.
To do it with one method, do this in the welcome controller:
public page( $page_id ){
// views/header.php
$this->load->view( "header" );
if( $page_id = "about" ){
$this->load->view("about"); // views/about.php
}
else if( $page_id = "contact" ){
$this->load->view("contact"); // views/contact.php
}
// views/footer.php
$this->load->view("footer");
}
This takes a single get variable and figures out what page to load in between the header and footer.
This way www.yoursite.com/page/about will load the about page, www.yoursite.com/page/contact will load the contact page
Now, if you want to get rid of the /page part, you need to do some URL rerouting in application/config/routes.php
Alternatively you could use several methods in one controller:
public about( ){
// views/header.php
$this->load->view( "header" );
$this->load->view( "about" );
// views/footer.php
$this->load->view("footer");
}
public contact( ){
// views/header.php
$this->load->view( "header" );
$this->load->view( "contact" );
// views/footer.php
$this->load->view("footer");
}
Now your URLs look nicer without routing, but you have to load the header/footer for every page.
do you really like to copy/paste many $this->load->view() to any controller function?
It's a spaghetti code. You can try next: for example we have main.php controller as default controller. This main controller contain main function:
public function index()
{
ob_start();
$this->load->model('mainmodel');
$data = $this->mainmodel->_build_blocks(); //return array with needed blocks (header, menu, content, footer) in correct order
foreach ($data->result_array() as $row) {
$this->load->module($row['block_name']);
$this->name = new $row['block_name'];
$this->name->index();
}
ob_end_flush();
}
So, each other controller also have index() function which can dispatch actions depends on url segments, prepare params etc.
Footer controller as example (I use Smarty as template engine):
public function index()
{
$this->mysmarty->assign('year', date("Y"));
$this->mysmarty->view('footer');
return true;
}
Content controller will have:
public function index()
{
$name = $this->uri->segment(1, 'index');
$act = $this->uri->segment(2, 'index');
$this->load->module($name);
$this->name = new $name;
$pageData = $this->name->_show($act);
if ($pageData)
{
$this->mysmarty->assign($name, $pageData);
}
$this->mysmarty->view($name);
}
Thats mean what if you want to show http://site.name/page/contactus , we do next:
1) main.php start cycle by needed blocks
2) firstly we show header.tpl by header controller
3) then we show menu
4) then we call content controller which parse url, found what he should call _show() function in Page controller and pass action='contactus' to it. _show() function can contain some switch/case construction which show templates depends of action name (contactus.tpl in this case)
5) in the end we show footer template
In such case we have flexible structure. All controllers should have index() functions and all controllers who can be called in content should have _show($act) function. Thats all.
In codeIgniter you can do that like this, you can load different views at the same time from your controller. for example:
for example in your navbar view you have a Contacts button in your menu that would look like this:
<a href='contacts'>Contacts</a>
In your controller:
public function contacts()
{
$this->load->view('header');
$this->load->view('navbar');
$this->load->view('sidebar');
$this->load->view('contacts_view');
$this->load->view('footer');
}
So we're assuming here that you have the following views already that is ready to be loaded (header.php, navbar.php, sidebar.php, contacts_view.php, footer.php).
UPDATE:
you don't need to have $_GET[] request, just provide the method name from your controller in the <a> anchor tag
in codeigniter i using template
first make template file in one folder with header.php, navbar.php, etc.
example : template.php
<?php
echo $this->load->view('header'); //load header
echo $this->load->view('navbar');//load navbar
echo $this->load->view('sidebar');//load sidebar
echo $this->load->view($body); //load dynamic content
echo $this->load->view('footer');//load footer
?>
second in controller
function index( ){
$data['body'] = 'home'; // cal your content
$this->load->view('template', $data);
}
I'm currently working on an existing website created in codeigniter.
Whenever a user enters a page, he gets redirected to frontpage.php, that checks if the user is logged in, if not he gets redirected to the login page.
Now, I have one page where this frontpage.php shouldnt be executed, and any user can enter it.
Any help is greatly appreciated.
Had a similar problem and solved it this way by using some online tutorials
1: Make a seperate loginpage (ex login.php) prior to the 'frontpage.php'.
2: Pass the login, password and a session variable to the frontpage.
3: Recode you 'frontpage.php' to check for the session variable passed by 'login.php'.
If u entered the page trough the normal way it will use the normal login.
if u entered the page trough the new 'login.php' page it will be picked up by the recoded 'frontpage.php' and bypass the normal way.
Hope this helps

Re-route everything to your pages controller and use this as your default
$route['default_controller'] = 'pages';
$route['(.*)'] = 'pages/index/$1';
-
class Pages extends CI_Controller
{
protected $currentUser = null;
public function __construct()
{
parent::__construct();
$this->currentUser = Auth::getCurrentUserObject(); //check user is logged in
}
public function index($uri='home')
{
$sizeOfSegments = sizeof($this->uri->rsegments);
if ($sizeOfSegments >= 3)
{
$uri = $this->uri->rsegments[3];
}
else
{
$uri = 'home';
}
$pageFound = Page::find($uri); //query the database
if (!$pageFound)
{
return show_404($uri); // find out where there were headed
}
unset($sizeOfSegments, $uri);
if(is_null($this->currentUser) OR !$this->currentUserHasPermissionToViewThisPage OR !$pageIsNotPublic)
{
return redirect('login');
}
$this->load->view();
}
}
make new controller
class Newpage extends CI_Controller {
public function index(){
$this->load->view('newpage');
}
}
now goto
yourhost.com/index.php/newpage
May be your default Controller have a coding of checking whether user is logged or not. Please remove or change the code in controller.
I think you need to delete the controller, it works like that!
I used Pagination in CodeIgniter.
This is my link in address bar on my localhost
PicTraveller/branches/1.0.1/Implementation/index.php/home
When I click on next then next 5 records will show. After I click on next:
PicTraveller/branches/1.0.1/Implementation/index.php/home/5
I then have to write for this in routes file:
$route['home/(:any)']= 'home/$1';
But this is not work . Please suggest me. Thanks in advance
You can write this without using routes as follow:
Pass parameter to function index on your home conroller in that your code is placed.
Parameter should be nullable as fist no record number is send.
i.e.
class Home extends CI_Controller
{
function __construct() {
parent::__construct();
}
function index($recordId = null) {
if (!empty($recordId)) {
//next button is clicked
} else {
// first time
}
}
}
