header white Data

Hello everybody,
I wanted to include a loop in my template header.php.
Unfortunately I get with the foreach an error message.
What have I done wrong?

Controller:

PHP Code:

<?php
    class Warenkorb extends CI_Controller
        {
            function __construct()
                {
                    parent::__construct();
                }

            public function header()
                {
                    $data['header_warenkorbs'] = $this->Warenkorb_model->header_warenkorbs();
                    $this->load->view('templates/header', $data);
                    // $this->load->view('test/index');
                    // $this->load->view('templates/footer');
                }
        } 


Model:

PHP Code:

<?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();
                }
        } 


header.php

Code:

<?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; ?>

You should always check a foreach variable is not empty before doing the foreach loop. The error is telling you your variable is not set. If it is not set, but you are trying to set it with your model call, then your model must not be returning the values you expected.

Looking at your models called function, which looks fine, are you sure you have any data in the table you refer to?

PS You could write it like this btw:

PHP Code:

public function header_warenkorbs()
{
      return $this->db->select('*')
            ->from('db_artikel')
            ->get()
            ->result_array();
} 


And since select * is the default, and get accepts a table name, you could do:

PHP Code:

public function header_warenkorbs()
{
      return $this->db->get('db_artikel')->result_array();
}
