we have two controllers one is members.php which is registering the user another one is reserv.php for reserving a ticket for busses.
I want to load second controller after completion of first controller class.
members.php
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class Members1 extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('member_model1');
}
public function index() {
$table = $this->member_model1->insert_members();
$data['members'] = $table;
//$this->load->view('header1', $data);
$this->load->view('reservation_view',$data);
//$this->load->view('members');
//$this->load->view('footer');
}
}
reserv.php
<?php
class reserve extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('member_model1');
}
function index() {
$table = $this->member_model1->get_members();
$data['members'] = $table;
//$this->load->view('header1', $data);
$this->load->view('reservation_view',$data);
//$this->load->view('reservation_view');
// $this->load->helper(array('form'));
//$this->load->view('reservation_view');
}
}
?>
To call a controller from another controller, you can use the function redirect() :
// In Members1 controller
redirect('/reserve/index');
Note that you won't be able to send data along with the redirect, such as when you load a view. To send data, you must use $this->session->set_flashdata(); because the redirects seem to use header() (I advise you to have a loot at this post).
// In Members1 controller
$this->session->set_flashdata('key', 'value');
redirect('/reserve/index');
By the way, when I look at your two classes, I wonder why you don't simply create a unique Ticket class with two methods like registerUser() and bookTicket() (these names are pure fancy, be free to use yours).

class Welcome extends CI_Controller{
function checker(){
if (!$_SESSION['bla']) {
$data['include'] = "REGISTER"; //first result
}else{
$data['include'] = "template";
}
$this->load->view('template', $data); //second result
}
//STOP HERE IF RESULT IS FIRST
function index(){
$data['include'] = "index";
$this->load->view('template', $data);
}
}
I want if in my page dont have session all user redirect to 'REGISTER' page, all classess, all functions to redirect in REGISTER page if dont have session. BUt if user has session just can use site normal. HOw to do this ?
I dont want in every class to put this check ... THanks
Create a controller MY_Controller in application/core/MY_Controller.php and extend the CI_Controller like this:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Controller extends CI_Controller{
function __construct() {
parent::__construct();
// do the checking here...
// if condition fails redirect...
}
}
Extend this MY_Controller class in your every controller instead of CI_Controller so in every request the checking would take place at first. For example:
class User extends MY_Controller {
// ...
}
I recently started using Codeigniter after having a structural problem in one of my Ajax-heavy applications. (You can read up on it if you want in my previous question)
I have a fairly short question. Currently I am making a lot of Ajax requests to different controllers. I open the controllers like this:
public function __construct()
{
parent::__construct();
$this->output->set_content_type('application/json');
}
And at the end of every function I do the following:
$this->returnValue['result'] = "ReturnedInfo";
$this->returnValue = json_encode($this->returnValue);
$this->output->set_output($this->returnValue);
The code is pretty clear in itself, but I don't want to keep repeating myself. The codeigniter manual says to do the following:
$this->output
->set_content_type('application/json')
->set_output(json_encode(array('foo' => 'bar')));
But I would still be repeating myself. Also, I don't want to add a function to every controller that does this, even if it does decrease redundancy.
Since all of my controllers return JSON, is there a way to set this globally in a config file maybe, or in any other way?
TL;DR I have this same piece of code in every controller/function. Since the output type is always the same, just not the result, is there a way to automate this process across every controller/function?
Create an Ajax_Controller that extends MY_Controller that extends CI_Controller.
The Ajax Controller will then inherit from both Controllers.
class Ajax_Controller extends MY_Controller
{
public function __construct()
{
parent::__construct();
if(!$this->input->is_ajax_request()) return show_error('Invalid Request');
}
public function jsonOutput($json)
{
//some data checking here....
return $this->output
->set_content_type('application/json')
->set_header("HTTP/1.1 200 OK")
->set_output($json);
}
}
-
class User extends Ajax_Controller
{
public function __construct()
{
parent::__construct();
}
public function userMethod()
{
$json = json_encode(array(
'' => ''
));
$this->jsonOutput($json);
}
}
Extend your controllers from your own base class rather than CI_Controller and put your repeatedly-used function(s) and constructor code in there. Something like:
class BaseController extends CI_Controller {
protected function index() {
$this->returnValue['result'] = "ReturnedInfo";
$this->returnValue = json_encode($this->returnValue);
$this->output->set_output($this->returnValue);
}
}
class Specific extends BaseController {
public function index() {
//do controller-specific stuff
parent::index();
}
}
I abstract this further if I have groups of controllers with shared code; for example, if I had a bunch of controllers that require the user to be logged-in I create AuthenticatedController, which extends BaseController and add session checks etc.
I do not know if the following is possible. If not other suggestions are appreciated.
In nearly all my controllers I will load some default views. For example header, footer and menu.
I would like to have certain variables auto load for each view.
If I take the header as an example. Into my header I will always load an array of $css scripts and an array of $javascript files.
$javascript[] = 'js/jquery.js';
$javascript[] = 'js/jqueryui.js';
But additionally, depending on the current page logic, I might want to add another javascript file to my $javascript variable.
$javascript[] = 'js/custom.js';
Then ideally, I would like these variables to be automatically inserted as data into the load of the view.
In other words, I just want to call:
$this->load->view('header');
How could this be achieved?
Create MY_Controller add a public array there then extend from MY_Controller
class MY_Controller extends CI_Controller {
public $data;
function __construct() {
parent::__construct();
$this->data['MYVAR'] = 'Something';
}
}
in your other controllers you just do it like this
class SomeClass extends MY_Controller {
function __construct () {
parent::__construct();
}
function index () {
$this->data['SomeOtherVar'] = 'xxx';
$this->load->view('viewname', $this->data);
}
}
You can use $this->load->vars in your Controller.
I use this in my_controller and all controllers are extend from MY_Controller
For example
<?php
class MY_Controller extends Controller{
public function __construct(){
parent::__construct();
$this->setGlobalViewVariables();
}
public function setGlobalViewVariables(){
$result = array();
$result['value1'] = 'value1';
$result['value2'] = 'value1';
$this->load->vars($result);
}
}
?>
you should create an hook for this, it is very simple
As I have read through articles, the best possible way to validate a user in all controllers of my application is to extend my own Controller that extends CI_Controller
But I can't make it work.
What I have is a members_controller that extends my MY_Controller.
in MY_Controller i have this piece of code, just to test if how am I going to utilize this.
<?php
class MY_Controller extends CI_Controller {
private $foo;
function __construct() {
parent::__construct();
$this->foo = 'hello world again';
}
}
in my members controller
<?php
class Members extends MY_Controller {
function index() {
$this->load->view('members');
}
}
in my members view
i want to access this variable i just set up, but i don't know how.
i tried echoing it out like this echo $foo, like this $this->foo
but neither work. thanks much!!
You need to pass the variable to your view file.
<?php
class Members extends MY_Controller {
function index() {
$data = array('foo' => $this->foo)
$this->load->view('members', $data);
}
}
Now you can refer to $foo inside your view. You may need to declare $this->foo as protected.
There's a video tutorial on MY_Controller that you may find useful at http://codeigniter.tv/a-10/Extending-the-core-MY_Controller-and-beyond
Have you tried passing the variable to the 'members view'.
$this->load->view('members',$foo);
You need to make $foo as protected and not private.
Then you will be able to access it in your controller that extends MY_Controller.php like this:
$this->foo
Today for the first time I used codeigniter 3. In the past I used version 2.x a lot of times. Now I can't extend CI_Controller:
application/core/MY_Controller.php
class MY_Controller extends CI_Controller {
private $data = array();
function __construct() {
parent::__construct();
date_default_timezone_set("Europe/Zagreb");
$this->data['foo'] = "bar";
}
application/controllers/Welcome.php
class Welcome extends MY_Controller {
public function index() {
$this->data['main_content'] = 'home';
$this->load->view('template/template', $this->data);
}
application/view/home.php
(this is view loaded by $this->data['main_content'])
If I try to echo any data declared in MY_Controller, I get an error.
<?php echo $foo; ?>
A PHP ERROR WAS ENCOUNTERED
Severity: Notice
Message: Undefined variable: foo
Filename: template/header.php
I need to create codeigniter base controller to check allowed ip address in database by mobel function if the ip is exists then user should go to home page but if the ip address is not exists and show 404 page in codeigniter, i can't find core folder in application folder
First, you need to extend a core class, call it MY_Controller.php
Save that file in: application/core/MY_Controller.php
class MY_Controller extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model('ip_table_model');
$this->load->library('input');
// assuming there's a function called "check_ip($ip_address)" in ip_table_model
if (!$this->ip_table_model->check_ip($this->input->ip_address()) {
redirect('error_404');
}
}
}
Now, we're assuming you have a model called ip_table_model which connects to database with list of IP addresses, and there's a function called check_ip which will validate whether user has access or not. This is relatively simple, and I won't show any examples on this.
The redirect('error_404'); page does not yet exist, you need to create a controller which shows your 404 page.
Now, for any other controllers in your project, instead of extends CI_Controller, make them extend MY_Controller instead.
Here's an example:
class Welcome extends MY_Controller {
function __construct()
{
parent::__construct();
}
function index()
{
$this->load->view('welcome_message');
}
}
Explanation: We're extending CI_Controller to create our own core controller, called MY_Controller. Inside, we're checking if user has access or not through the constructor, which will be called in every other controller in the project.

Answer is here (section Extending Core Class).
1.7.2 has a different structure to 2.0.*, therefore there is no core folder in application
In Core Create a new Class .
Name MY_Controller.php
class MY_Controller extends CI_Controller {
// Write your functions here which you wanna use throughout the website
public function abc (){
echo "Helllo";
}
}
class Welcome extends MY_Controller {
function __construct()
{
parent::__construct();
}
function your_custom_fuctions()
{
$this->abc(); //echo Hello...
//Anything you want to do
}
}
function admin_view($view_name = "", $header_info = NULL, $sidebar_info=NULL,$page_info = NULL, $footer_info = NULL, $data_info = ""){
$this->load->view('Admin/includes/header', $header_info);
$this->load->view('Admin/includes/Left_sidebar', $sidebar_info);
$this->load->view($view_name, $page_info);
$this->load->view('common/footer', $footer_info);
}
