I am trying to user the Codeigniter pagination and I receive the following error "Fatal error: Call to undefined method Pagination::initialize()".
I found a few post with the same issue but they all stated the solution is to auto load the Pagination class which I am already doing. The only issue I can think of is that my class uses custom controller "MY_Controller" which extends the CI controller. Below is my code, please help. Thanks in advance.
MY_Controller.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Controller extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->init();
}
}
Main Controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Main extends MY_Controller {
function index()
{
$this->display();
}
function display()
{
//pagination settings
$config['base_url'] = base_url();
$config['total_rows'] = 200;
$config['per_page'] = 50;
$this->pagination->initialize($config);
}
}
If you made a custom controller and extend it with core My_Controller than load pagination library inside the display() function:
$this->load->library('pagination');

I'm using Codeigniter 3 and I need some data available to all methods. I will query the data from the database and then I need to display it on every page.
I have created a MY_Controller extending CI_Controller and saved it in /application/core/
But I am getting this error:
Fatal error: Call to undefined method Area_model::get_user_locations()
MY_Controller:
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class MY_Controller extends CI_Controller {
public $location_data;
function __construct()
{
parent::__construct();
$this->load->database();
$this->load->model('area_model');
$org_id = $this->session->userdata('org_id');
$this->location_data = $this->area_model->get_user_locations($org_id);
}
}
Can i access models and the database from within MY_controller?
Area_model.php
// get all areas for an organisation
public function get_user_locations($org_id) {
$areas = $this->db->get_where('areas', array('org_id' => $org_id));
$area_array = $areas->result_array();
return $area_array;
}
MY_Controller
not used to direct any function to __construct()
__construct to only load to any model
write other function to MY_Controller look like this
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class MY_Controller extends CI_Controller
{
public $location_data;
function __construct()
{
parent::__construct();
$this->load->database();
$this->load->model('area_model');
$org_id = $this->session->userdata('org_id');
}
}
function functionname()
{
$this->location_data = $this->area_model->get_user_locations($org_id);
}
Area_model.php
public function get_user_locations($org_id)
{
$areas = $this->db->get_where('areas', array('org_id' => $org_id));
$area_array = $areas->result_array();
return $area_array;
}
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'm working on a calendar planning provided by [easyappointments][1] but now I'm stuck on this error by yesterday. In the main page users.php I've added the following:
<?php
require_once("application/models/impostazioni_model.php");
$this->load->model('impostazioni_model');
$this->impostazioni_model->load_colours();
?>
the require_once find correctly the file impostazioni_model.php but when I enter in the page users.php I see this error:
Fatal error: Call to a member function load_colours() on a non-object
on this line: $this->impostazioni_model->load_colours();
in the class impostazioni_model.php I've this content:
<?php if ( ! defined('BASEPATH')) exit('Direct execution not allowed.');
class Impostazioni_Model extends CI_Model
{
public function __construct()
{
parent::__construct();
}
public function load_colours()
{
echo "print";
}
}
?>
I've followed the codeigniter documentation, in particular the class model must be in capital letter so I don't know what I'm wrong. Someone could help me out?
In Controller
Path - application/controllers
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Admin extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('impostazioni_model'); //this will show "Print" word on browser.
}
function index() {
$this->impostazioni_model->load_colours();
}
}
In Model
Path - application/model
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Impostazioni_model extends CI_Model {
function __construct() {
parent::__construct();
}
function load_colours() {
echo "print";
}
}
I am fairly new to Codeigniter and am trying to call in a function from my model but I cannot get it to work. Can anyone see what I am doing wrong here?
Controller (farm.php):
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Farm extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model('harvest_first');
}
function harvest()
{
echo $this->harvest_first->harvest();
}
}
Model (harvest_first.php):
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Harvest_first extends CI_Model
{
public function __construct()
{
parent::__construct();
}
public function harvest(){
return "THE FUNCTION";
}
}
?>
I am trying to echo "THE FUNCTION", but no matter what I do I cannot get it to work as expected.
Thanks,
Simon
Try this
class Harvest_first extends CI_Model
change to :
class Harvest_first_model extends CI_Model
and in controller call like this:
$this->load->model('harvest_first_model');
and
$this->harvest_first_model->harvest();
Check here
There is no need to add "_model" to model that depends on you
just Load the Model and that its use autoload.php and add model there it is a good pratices
I have been working on a session validation for my login to make sure that a user is logged in to view pages. I keep getting this error:
Fatal error: Class 'MY_Staffcontroller' not found in /usr/local/var/www/CodeTest
/ci/application/controllers/staff_c.php on line 3
My staff_c page looks like so :
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Staff_c extends MY_Staffcontroller {
function homepage()
{
$data['main_content'] = 'homepage_view';
$this->load->view('includes/template', $data);
}
}
I have been reading same questions all over the place and they say the same thing pretty much...
Is your controller located in application/core?
Well yes it is. I can't seem to get passed this hump!
This is the code within My_Staffcontroller.php:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_staffcontroller extends CI_Controller {
function __construct()
{
parent::__construct();
$loggedin = $this->session->userdata('loggedin');
if(!isset($loggedin) || $loggedin != TRUE);
{
die($this->load->view('denied'));
}
}
}
I know this is user error as this is only my second day with CodeIgniter but I can't seem to find proper workaround for this?
I have tried this tutorial and still nothing and also this
Even following this video has me stuck on the session part.
And I just can not get this to work.
Remember Linux is case-sensative whereas Windows is case-insensative.
place you're MY_Staffcontroller inside application/core/MY_Controller.php file
Your MY_Controller.php file should look like this (minus all you're other functions, this is a minimal example)
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Controller extends CI_Controller
{
public function __construct()
{
parent::__construct();
}
}
class MY_Staffcontroller extends MY_Controller
{
public function __construct()
{
parent::__construct();
}
public function sayHello()
{
echo "Hello, I am a function within MY_Staffcontroller.php";
}
}
Example
This will be located in /application/controllers directory
Basically any protected and public functions located in either MY_Controller OR MY_Staffcontroller will be accessible from derived controllers that extend the extended controller. In this case it would be MY_Staffcontroller
class Public_Staff_Controller extends MY_Staffcontroller
{
public function __construct()
{
parent::__construct();
}
public function index()
{
$this->sayHello();
}
}
/* end of file /application/core/MY_Controller.php */
