I have setup the codeigniter, default controller is working(welcome.php) but when i add new controller its not working
Default controller :
defined('BASEPATH') OR exit('No direct script access allowed');
class Welcome extends CI_Controller {
public function index()
{
$this->load->view('welcome_message');
}
public function testing()
{
$this->load->view('test');
}
}
http://localhost/appointment/index.php/welcome/ (working)
New controller
class democontroller extends CI_Controller {
public function index()
{
$this->load->view('test');
}
}
http://localhost/appointment/index.php/democontroller/ (not working)
Change the following code:
class democontroller extends CI_Controller {
}
to
class Democontroller extends CI_Controller {
}
and save this file with name Democontroller.php and try again.
Note: controller name first character must be capital as per naming convention.

My Project Structure is
application
controllers/site
core/
views/site
I want when i entered http://mywebsite admin has to be loaded and when i entered http://mywebsite/site frontend has to be loaded
I went through some tutorials and i have done changes below
In config/routes.php
$route['default_controller'] = 'admin';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
$route['site'] = 'site/home';
In core/My_Controller.php
defined('BASEPATH') or exit('No direct script access allowed');
class MY_Controller extends CI_Controller
{
function __construct()
{
parent::__construct();
}
}
class Admin_Controller extends MY_Controller
{
function __construct()
{
parent::__construct();
}
}
class Site_Controller extends MY_Controller
{
function __construct()
{
parent::__construct();
}
}
In controller/site/Home.php
defined('BASEPATH') or exit('No direct script access allowed');
class Home extends Site_Controller
{
public function __construct()
{
parent::__construct();
}
public function index()
{
$this->load->view("site/index.php");
}
}
But I am getting 404 when I opened http://mywebsite/site
Please help me
$route['site'] = 'site/home';
What that line does is that it defines a route that looks for a method called home inside the controller called Site viz. Site_Controller.
So you are getting the 404 error because your Site_Controller does not have the home method.
Try changing the Site_Controller like so...
class Site_Controller extends MY_Controller
{
function __construct()
{
parent::__construct();
}
# added this method
public function home()
{
$this->load->view("site/index.php");
}
}
Well i have defined a derived class from CI_Controller known as application that is present in the system/core/folder
<?php
Class Application extends CI_Controller {
function __construct() {
parent::__construct();
}
}
?>
and derived an class from application named as home which displays the home page
<?php
Class Home extends Application {
function __construct() {
parent::__construct();
}
public function index() {
$this->load->view("Home");
}
}
?>
But i still get an error saying that Class 'Application' is not found
Change core class name from 'Application' to 'MY_Controller'(class name must ends with _Controller) and save it as MY_Controller.php
Class MY_Controller extends CI_Controller {
function __construct() {
parent::__construct();
}
}
Then extend the application controller class
Class Home extends MY_Controller {
You can use any words instead of MY_. For this change the following line in config.php
$config['subclass_prefix'] = 'MY_';
Make sure only Uppercase letters are allowed.
I am using PHP MVC CI. BaseController and LoginController are both inside Controller Folder. When I run the Login Controller. It says..
Class 'BaseController' not found
Login Controller
<?php
if ( ! defined('BASEPATH')) die('No direct script access allowed');
class loginController extends BaseController {
function __construct() {
parent::__construct();
}
public function login() {
$this->load->View("template/header");
$this->load->View("login_view");
}
}
?>
Base Controller
<?php
class BaseController extends CI_Controller {
function __construct()
{
session_start();
$this->load->library('session');
parent::__construct();
}
}
?>
Any idea why this is happening ?
If you need a parent controller than should be in
Path - application/core/MY_Controller.php
http://www.codeigniter.com/user_guide/general/core_classes.html
<?php
class MY_Controller extends CI_Controller {
public function __construct() {
parent::__construct();
}
}
If you also autoload sessions then you will not need to use session_start.
http://www.codeigniter.com/user_guide/libraries/sessions.html
Filename: Welcome.php must be first letter uppercase in CI3
<?php
class Welcome extends MY_Controller {
}
CI 3 is case sensitive
Both user guides now here. CI2 & CI3 http://www.codeigniter.com/docs
You just need to change the file path , as follows:
application > controllers > Login.php
<?php
if ( ! defined('BASEPATH')) die('No direct script access allowed');
class loginController extends BaseController {
function __construct() {
parent::__construct();
}
public function login() {
$this->load->View("template/header");
$this->load->View("login_view");
}
}
?>
And,
application > core > Base_controller.php
<?php
class BaseController extends CI_Controller {
function __construct()
{
session_start();
$this->load->library('session');
parent::__construct();
}
}
?>
Codeigniter wont load it from the same folder.
You either put both classes in the same file, not desirable or put the base controller in application/core.
You will need to also set your prefix for you extended controller, for example BASE_Controller.
application/config/config.php
$config['subclass_prefix'] = 'BASE_';
Codeigniter has good docs, and what you are after can be found here
I will extend the controller based of login typical, so I create on application directory like this:
core
-MY_Controller
-public controller
MY_Controller
<?php
if (!defined('BASEPATH')) exit('No direct script access allowed');
class MY_Controller extends CI_Controller
{
public function __construct()
{
parent::__construct();
}
}
public controller
<?php
class Public_Controller extends MY_Controller
{
//Some Logic here
public $layout = 'layout';
}
Now, time to use those things.
I write on application/route $route['default_controller'] = 'Home';
So, the controll that named Home would be like this :
<?php
class Home extends Public_Controller {
public function index() {
$this->load->view('public/home');
}
}
But unfortunately, it gives me error like this :
Fatal error: Class 'Public_Controller' not found in C:\wamp\www\egi\application\controllers\Home.php on line 5
Why I can not to extends the sub class ?
NOTE
But if I extends from MY_Controller, its success
<?php
class Home extends MY_Controller {
public function index() {
$this->load->view('public/home');
}
}
Any help it so appreciated
You can do this in one of the following ways.
Have a file named Public_controller in "application/core" & include that file in your application/core/MY_Controller.php file.
Define Public_Controller inside MY_Controller file which is autoloaded by default which means you'd end up with something like this.
File: application/core/MY_Controller.php
class MY_Controller extends CI_Controller {
public function __construct () {
parent::__construct();
}
}
class Public_Controller extends CI_Controller {
public function __construct () {
parent::__construct();
}
}
I am having trouble loading model in sub module controller from sub module itself.
I am having few modules and sub-modules as below
modules/admin/
modules/admin/models
modules/admin/controllers
modules/admin/views
modules/admin/models/dashboard/
modules/admin/controllers/dashboard/
modules/admin/views/dashboard/
modules/admin/models/plugs/
modules/admin/controllers/plugs/
modules/admin/views/plugs/
Each M/V/C has own files in it.
Now I have created model in modules/admin/models/plugs/ just for testing purpose something like below
Plugs Model
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Plugs extends CI_Model
{
public function __construct()
{
parent::__construct();
}
public function mymeta()
{
return 'plugs model loded';
}
}
And now trying to load into Plugs Controller as below
<?php (defined('BASEPATH')) OR exit('No direct script access allowed');
class Plugs extends MX_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('plugs');
}
public function index()
{
$this->load->view('plugs/index');
}
public function get_plugin_meta()
{
echo $this->plugs->mymeta(); // this is the method from Plugs Models
}
}
But when I tried to access the URL http://localhost/mysite/admin/plugs/get_plugin_meta or http://localhost/mysite/admin/plugs it is giving me below error.
An Error Was Encountered
Unable to locate the model you have specified: plugs
So than how to load model in controller?
Your module is not plugs. It's admin because of modules/admin
You should use like $this->load->model('module/model');
Try this one:
$this->load->model('admin/plugs/plugs'); // module/folder/file
Important
Controller class name and model class name was conflicting.
Just rename model filename with: plugs_model.php
and change class name with: class Plugs_model extends CI_Model
$this->load->model('admin/plugs/plugs_model');
echo $this->plugs_model->mymeta(); // plugs model loded
