country,state,city.

write code on country combobox change index event.
select state from [table] where country='selected country'

store result in dataset or datatable and bind it with state

Answer / mustkeem

You try this ...script...

<?php
require_once("cities/dao/BaseDao.php");

class CitiesDao extends BaseDao {

public function getCountries() {
$query = "select * from tb_countries order by country asc";
return
$this->execute($this->connection->prepareQuery($query,
Array()));
}

public function getCountryById($idCountry) {
$query = "select * from tb_countries where id_country =
:id_country";
return
$this->getSingleRow($this->connection->prepareQuery($query,
Array("id_country" => $idCountry)));
}

public function getStatesByCountry($idCountry) {
$query = "select * from tb_states where id_country =
:id_country order by state asc";
return
$this->execute($this->connection->prepareQuery($query,
Array("id_country" => $idCountry)));
}

public function getStateById($idState) {
$query = "select * from tb_states where id_state = :id_state";
return
$this->getSingleRow($this->connection->prepareQuery($query,
Array("id_state" => $idState)));
}

public function getCitiesByCountryAndState($idCountry,
$idState) {
$query = "select * from tb_cities where id_country =
:id_country and id_state = :id_state order by city asc";
return
$this->execute($this->connection->prepareQuery($query,
Array("id_country" => $idCountry, "id_state" => $idState)));
}

public function getCityById($idCity) {
$query = "select * from tb_cities where id_city = :id_city";
return
$this->getSingleRow($this->connection->prepareQuery($query,
