Help with Controller

[eluser]Unknown[/eluser]
I just started using CI about weeks ago, and I'm trying to experiment what this framework can do by creating my own CMS-sort of portal.

I have a page called dashboard (editor.php). It is basically everything - events, uploads, posts, etc.
Now, I have a controller for dashboard which is admin.php

It looks like this:

Code:

class Admin extends CI_Controller
{
function __construct()
{
  parent::__construct();
  $this->is_logged_in();
}

function index()
{
  $this->load->view('login');
}

function dashboard()
{
  $this->load->model('gallery_model');
  $this->load->model('site_model');
  
  $data = array();
  
  $data['images'] = $this->gallery_model->get_images();
  $data['events'] = $this->site_model->get_events();

  $this->load->view('admin/editor', $data);
}
function is_logged_in()
{
  $is_logged_in = $this->session->userdata('is_logged_in');
  
  if (!isset($is_logged_in) || $is_logged_in != true)
  {
   echo '[removed]alert("You are not logged in.");[removed]';
   redirect('login', 'refresh');
  }
}
}

Now, basically my problem is at the 'dashboard' function. Because I need to call 2 or more models. Like you can see:

Code:

$this->load->model('gallery_model');
$this->load->model('site_model');

And of course, I need to call their methods.

Code:

$data['images'] = $this->gallery_model->get_images();
$data['events'] = $this->site_model->get_events();

But, it's giving me errors:

A PHP Error was encountered
Severity: Notice
Message: Undefined property: Admin::$site_model
Filename: controllers/admin.php
Line Number: 24

Fatal error: Call to a member function get_events() on a non-object in ...\application\controllers\admin.php on line 24

It's pertaining to the line where I am calling the get_events function.

I've checked my config files and see everything is loaded okay.

Code:

$autoload['libraries'] = array('database', 'session', 'xmlrpc', 'parser');

because I was expecting to show the events in the left sidebar and the latest uploads (of images) to be shown on the right part of the contents.

I already tried searching some solutions around the net, but didn't work for me. I also saw some same topics about my problem, but we have quite a different scenario.

Can anyone help me out!?
Thank you.

Welcome to the CodeIgniter forums!

Please make sure error reporting is fully enabled. Just put this at the top of your index.php file:

Code:

ini_set('display_errors', '1');
error_reporting(E_ALL);

Also, please post your Site_model model code. I'm currently trying to help someone with a similar issue, and I have to say, I'm a bit baffled.

Are you using a Mac by any chance?
What version of PHP are you using?
Did this ever work, or is it a problem that's only just cropped up?

Thanks for the reply, TheFuzzy0ne.

Btw here's my code for site_model:

Code:

class Site_model extends CI_Model
{
function get_events()
{
  $q = "SELECT * FROM calendar";
  
  $query = $this->db->query($q);
  
  if ($query->num_rows() > 0)
  {
   foreach($query->result() as $row)
   {
    $data[] = $row;
   }
   return $data;
  }
}
}

I also put the error_reporting, and just shows the same error.

Fatal error: Call to a member function get_events() on a non-object in ...\Rustedsoul\application\controllers\admin.php on line 24

No, I am not using MAC. And my PHP version is: PHP Version 5.4.7

Well, at first I only call the first model "gallery model" and everything works fine. So I proceeded to the next model and load it in my function and also access the method just like the ones I did before.
After having these:

Code:

$this->load->model('gallery_model');
$this->load->model('site_model');
  
$data = array();
  
$data['images'] = $this->gallery_model->get_images();
$data['events'] = $this->site_model->get_events();

$this->load->view('admin/editor', $data);

The error appeared, and I'm stuck on this.

Thanks for your response, btw.

I have a theory. I suspect that somewhere you're assigning a value to $this->site_model, and removing the model from it.

Please try the following as your controller constructor:

Code:

function __construct()
{
    parent::__construct();
    $this->load->model('site_model');
    die(print_r($this->site_model->get_events(), TRUE));
}

What I hope to see, is your model method working as expected. If it does, then your problem may have something to do with gallery_model.

Another thing to try would be to make a copy of site_model and rename it (site_model2 will do fine), and then load that and see if it works. It's a peculiar problem, but I suspect there's a simple solution.
