codeigniter template header white Data - php

Question

how can I embed a foreach with my header?
I have already tried as in the code.
But with the output I get only "Undefined variable: header_warenkorbs" raus.
Although I am involved in the controller with the value data.
What am I doing wrong?
Controller:
<?php
class Warenkorb extends CI_Controller
{
function __construct()
{
parent::__construct();
}
public function header()
{
$data['header_warenkorbs'] = $this->Admin_model->header_warenkorbs();
$this->load->view('templates/header', $data);
// $this->load->view('test/index');
// $this->load->view('templates/footer');
}
}
Model:
<?php
class Warenkorb_model extends CI_Model
{
public function header_warenkorbs()
{
$this->db->select('*');
$this->db->from('db_artikel');
$query = $this->db->get();
return $query->result_array();
}
}
View:
<ul class="nav navbar-nav navbar-right">
<li class="dropdown">
<span class="glyphicon glyphicon-shopping-cart"></span><span class="cart-items-count"><span class=" notification-counter">243</span></span>
<ul class="dropdown-menu dropdown-cart" role="menu">
<?php foreach($header_warenkorbs as $warenkorb): ?>
<li>
<span class="item">
<span class="item-left">
<span class="item-info">
<span>Item name</span>
<span>23$</span>
</span>
</span>
<span class="item-right">
<button class="btn btn-xs btn-danger pull-right">x</button>
</span>
</span>
</li>
<?php endforeach; ?>
<li class="divider"></li>
<li><a class="text-center" href="<?php echo base_url(); ?>warenkorb/index">Warenkorb</a></li>
</ul>
</li>
</ul>

Answer 1

Unless it is a typo or you're not showing us something the problem could be with this line.
$data['header_warenkorbs'] = $this->Admin_model->header_warenkorbs();
The model code you show is Warenkorb_model not Admin_model. Seems like the above code should maybe be
$data['header_warenkorbs'] = $this->Warenkorb_model->header_warenkorbs();
You don't show where you load the model. It is loaded somewhere... right? It is common practice to load models in the constructor of the Controller that uses the model.
class Warenkorb extends CI_Controller
{
function __construct()
{
parent::__construct();
$this->load->model('Warenkorb_model');
}
// other code
}
Do you realize you are not actually doing anything with the $header_warenkorbs in your foreach loop? You never use $warenkorb.

Answer 2

you need to echo it (example:)
<?php
echo '<table>
<tr>
<td>Name</td>
<td> .$name.</td>
</tr>
</table>';
?>
just edit it to your needs, im too lazy
