Cannot load a model in codeigniter - codeigniter

Question

I failed to load a model from my controller
This is the controller file, article.php:
<?php
class Article extends CI_Controller {
function show($id) { //id'ye gore getir
$this->load->model('articles_model');
$parameter = $this->articles_model>getarticle($id);
$this->my_template->build('article_view', $parameter);
}
}
?>
This is the model file, articles_model.php:
<?php
class Articles_model extends CI_Model {
function __construct()
{
// Call the Model constructor
parent::__construct();
}
function Getarticle($id) {
parent::Model();
$query = $this->db->get_where('articles', array('id' => $id));
$data['articles'] = $query->result();
return $data;
$query->free_result();
}
}
?>
just to add, i even tried to load it from autoloader, still no chance, i assume something is wrong with the model, or the whole system broke.
up: the models loads without problems, if i put echo in __construct function, it works, however, i cannot call the getarticle function. geez
UP: I did it! according to http://grasshopperpebbles.com/codeigniter/codeigniter-call-to-a-member-function-on-a-non-object/
i used
$CI =& get_instance();
and called the function
$CI->articles_model->getarticle($id) and it called the function

Answer 1

It should be,
$CI =&get_instance();
$CI->load->model('articles_model');
$parameter = $CI->articles_model>getarticle($id);

Answer 2

There's a parse error in the following line:
$parameter = $this->articles_model>getarticle($id);
It should be:
$parameter = $this->articles_model->getarticle($id);
Does that fix your problem? If not, what error message are you seeing?

Answer 3

Leif's answer is the right one. Just to add one thing: you don't have to use the long variable name like $this->articles_model over and over, by using the second parameter:
$this->load->model('articles_model','artm');
$parameter = $this->artm->getarticle($id);
Just a little faster to type, and can reduce typos like the one in your sample.
