Setting a global variable in a controller?

Hannes i think you are looking at the wrong code

Code:

// Get the table fields
        $fields = $this->db->list_fields('categories');
        $omit = array(
                         'ID',
                     );
        
        while (list ($key, $val) = each ($fields)) {
        
          if (in_array ($key, $omit)) unset ($fields[$key]);
        
        }

He uses it to remove fields he got from the db->list_fields method.
