Help with GET

Hello, everybody,
I have a problem with the GET.
I want to transfer three values where two values are present or not (where_or).
But somehow none of the values are transferred and I don't know why.

            $data['title'] = 'Edition Liste';
            $data['edition_listes'] = $this->Edition_model->edition_listess($slug);
            $this->load->view('templates/header', $data);
            $this->load->view($url, $data);
            $this->load->view('templates/footer');

edition.php (test page)

Code:

<?php echo validation_errors(); ?>
<?php echo $slug; ?>

show the contents of your routes file, there might be an error there

Which "GET" do you mean? The this->db->get(), or php's super-global $_GET?
Please, give us an example of the complete url to call the edition/edition method with 3 values.

Where are you getting the $url from? You need to show more code and what type of get your using.

If your trying to pull these off of the url then you need to use CodeIgniter segment methods.

What did you Try? What did you Get? What did you Expect?
