db->get Error

[eluser]Unknown[/eluser]
I have fixed my own issue. Instead of passing $db to the function I used

Code:

$obj = get_instance();

The resulting code for the functions is:

Code:

/* Returns an array containing provinces */
function get_provinces(){
    $obj = get_instance();
    $query=$obj->db->get('provinces');
    $provinces[0] = 'Not in US or Canada';    
    foreach($query->result_array() as $row) {
        $province_id = $row['province_id'];
        $province = $row['province'];    
        $provinces[$province_id]= $province;
    }
    $query->free_result();
    return $provinces;
}

/* Returns an array containing countries */
function get_countries(){
    $obj = get_instance();
    $query=$obj->db->get('countries');
    $countries[0] = 'choose one';
    foreach($query->result_array() as $row) {
        $country_id = $row['country_id'];
        $country = $row['country'];    
        $countries[$country_id] = $country;
    }
    $query->free_result();
    return $countries;
}
