I'm trying to work with the CI framework (PHP), and not having much luck with the core "Input" class.
Here's my code:
$user_name = $this->input->post('username');
$password = $this->input->post('password');
This is the result when I try to load the controller:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Login::$input
Filename: controllers/login.php
Line Number: 24
Any Tips?
Make sure that your controller extends CI_Controller and that you call the parent constructor in your own:
class Login extends CI_Controller {
public function __construct() {
parent::__construct();
}
/* the rest of your code... */
}

Hi im trying to load two models in my controllers by using this:
class Customers extends CoreAPI
{
public function __construct()
{
parent :: __construct();
$this->load->model('Customers_model', 'Customers');
$this->load->model('Customers/Handler_model');
}
public function test_get()
{
$this->Handler_model->test;
exit;
}
However, I always get this error:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: CI::$test
Filename: core/Model.php
Line Number: 73
I tried the two different ways of loading a model as stated.

Please help. Thank you.
class Handler_model extends CI_Model
{
public function __construct()
{
parent :: __construct();
}
public function test()
{
echo 'TEST';
}

I am a newbie to Codeigniter and trying to build a service registration page. Not just the page but the whole website has this error.
$autoload['model'] = array('User_model','Material_model');
$autoload['libraries'] = array('database','form_validation');
class services extends CI_Controller {
public function service1()
{
$this->form_validation->set_rules('type','Type',trim|required);
$this->form_validation->set_rules('area','Area',trim|required);
$this->form_validation->set_rules('quantity','Quantity',trim|required);
$this->form_validation->set_rules('details','Details',trim|required);
$this->form_validation->set_rules('name','Name',trim|required);
$this->form_validation->set_rules('number','Number',trim|required);
$this->form_validation->set_rules('location','Location',trim|required);
if($this->form_validation->run()==FALSE){
$data['main_view']="page_view";
$this->load->view('layouts/main',$data);
} else{
$this->user_model->create_user();
redirect('/');
}
I'm getting this error in user model from material model. Th
Actually, you should load the model in your parent construct.
For example:
class services extends CI_Controller {
function __construct(){
parent::__construct();
$this->load->model('your_directory_model, 'your_initialize_model');
}
}
And then, if you want to use your model. you can build code like i write below in your method.
$this->your_initialize_model->your_model_method();
I haven't used CodeIgniter in over a year. I remember it was useful for quick, simple projects but I seem to have fallen at the first hurdle here. I can't seem to load my default view. Here is the controller:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Home extends CI_Controller {
private $data = array();
public function __constructor() {
parent::__construct();
}
public function home() {
$this->load->view('header');
$this->load->view('nav');
$this->load->view('home');
$this->load->view('footer');
}
}
This gives me:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Home::$load
Filename: controllers/home.php
Line Number: 13
But I can't figure out why.
In my config I have set 'html', 'url' and 'form' to autoload. And my routes defaults correctly to 'home'. It's kinda frustrating because I know it's something really simple that I'm forgetting here.
Your __constructor is wrong. Use __construct instead of __constructor
public function __construct()
{
parent::__construct();
}
Your method has same name with the view you are calling which is home
I have a CodeIgniter spark defining&autoloading a class libraries/Nci_nicecontroller.php:
class Nci_nicecontroller extends CI_Controller {
//...
}
//autoloaded using $autoload['libraries'][]='nci_nicecontroller';
now I want to use Nci_nicecontroller in my application's controller, e.g.:
class Welcome extends Nci_nicecontroller {
//...
}
//autoloaded using $autoload['sparks'][]='nci-extensions/0.0.4';
obviously, I can't just $this->load->spark in my controller's constructor, because it's required on class extension.
when not using sparks, I just put the Nci_nicecontroller in a core/MY_Controller.php, but with sparks, this won't work.
I tried autoloading the spark in my application, which didn't work.
Then I tried:
get_instance()->load->spark('nci-extensions/0.0.4');
in the header of controllers/welcome.php, which gives me following errors:
Severity: Notice
Message: Trying to get property of non-object
Filename: controllers/welcome.php
Line Number: 2
--and--
Fatal error: Call to a member function spark() on a non-object in
C:\xampp\htdocs\CodeIgniter_demo\application\controllers\welcome.php on line 2
what shall I do?
Try to do something like that:
class Wellcome extends CI_Controller {
protected static $_nci = null;
public function __construct(){
parent::__construct();
$this->_nci = $this->load->spark('nci-extensions/0.0.4');
}
public function index(){
$result = $this->_nci->getSomething();
echo $result;
}
}
I'm trying to get familiar with CI and I have run into a problem while trying to implement my Model. I get the following error:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Home::$OrderModel
Filename: controllers/home.php
Line Number: 12
My assumption was that I was breaking some convention with the naming of the Model. If
I change the line in question and call the model using all lower case:
$data['query'] = $this->ordermodel->get_all_workorder_names();
Nothing is returned to the view.. blank page; no source, no error.
Here is my model:
<?php
class OrderModel extends Model{
function OrderModel()
{
parent::Model();
$db = $this->load->database();
}
function get_all_workorder_names()
{
$this->db->select('name');
$query = $this->db->get('WorkOrder');
return $query->result();
}
}
?>
This is the calling controller:
<?php
class Home extends Controller{
function Home()
{
parent::Controller();
$this->load->model('ordermodel');
$this->load->helper('url');
}
function index()
{
$data['query'] = $this->OrderModel->get_all_workorder_names();
$this->load->view('Header');
//$this->load->view('Home',$data);
$this->load->view('Footer');
}
}
?>
What am I doing wrong? A side question: Is there a debugger available for PHP in Eclipse?
Use $this->ordermodel. The variable name will match whatever you use with load->model()
