Adding to data array for all functions in model

[eluser]Pascal Kriete[/eluser]
$data is a class variable, so you have to access it in the class scope, by using $this:

Code:

function getCategories(){
    $query = $this->db->query("SELECT * FROM article_categories");
    $categories = $query->result_array();
    $this->data['categories'] = $categories;
    return $this->data;
}
