Just get all categories and create a db-request for each of them. as i told, you wont be able to avoid learing php.
Code:
$all_cats = // get all cat, how every you want/got to
foreach($all_cats as $cat){
$data['all_my_stuff'][] = // getting ur stuff with $cat
}
$this->load->view('view',$data);
this way you could use $all_my_stuff in the view.
