Loading Header and Footer in codeigniter

[eluser]victorche[/eluser]
thanks for this, really usefull
but i have a question
in my header.php, which is included in the main template, i have:

Code:

<p>Wellcome, &lt;?php echo $user; ?&gt;</p>

and because i have this header on every page, i want to extend CI_Controller with MY_Controller. And in MY_Controller i have:

Code:

$user = $this->auth->get_user();
$data['user'] = $user->username;

in my template.php file, i also have:

Code:

<?php $this->load->view('header'); ?>

but the result is ... "Undefined variable: User"
any ideas how to include something globally, with MY_Controller and this simple template library ?
