GET will not be transmitted - php

Question

I have a problem with this GET.
I want to pass on three values (ygo, dane, 1) with a link to index, so that these values are entered in the respective WHERE.
But unfortunately there is no value on the page and I just don't know why.

$array = explode ('/',$url);

$this->load->view('templates/header', $data);
$this->load->view($url, $data);
$this->load->view('templates/footer');

$url = 'edition/edition';

It looks like you are not passing the third argument to edition($tcg,$id,$short). That likely means your model is using null for the value of $short in the call to $this->db->or_where('db_edition.tb_edition_kurzel', $short); so it is probably not returning any records.
Your code could be a lot easier to read. Here is code-snippet suggestion on how to create the link to the edition controller
...
<div class="list-group">
<?php
$tcg = $edition_liste['tb_edition_tcg'];
if($edition_liste['tb_edition_kurzel'] !== '') // use a more reliable test for an empty string than > ''
{
$id = $edition_liste['tb_edition_kurzel'];
}
else
{
$id = $edition_liste['tb_edition_id'];
}
$short = 1;
?>
<a href="<?= base_url("edition/edition/$tcg/$id/$short"); ?>" class="list-group-item list-group-item-action list-group-item-secondary">
...
In case you are not familiar with the syntax <?= is exactly the same as <?php echo - but with a lot less typing.
Now, a bonus suggestion. I'm not sure exactly why you are using this code
$url = 'edition/index';
There is a way to get the current controller and method without hard-coding it.
$url = $this->router->class . '/' . $this->router->method;
That way if you rename the controller or the method you don't have to change the hard-coded string. Yeah!
CodeIgniter does not document the router class, but the source code is in /system/core/Router.php and every controller will have an instance of the router class available as the property $this->router.
