thanks you, I create three dropdown list for region, province and by cities, the first dropdown list is used for the region, if i select from the region the second selector will display the list of province according to region and at desame time my cities list selector will also change according to province i select too. probably i done it well but, the problem i could not get the value to display on selected list.

here are the part of my code.

 

<?php switch($select) { case "city": { if ($select!=all) { $city=$select; $select="city"; } else $city=$select; $heading="Hotels for \"".city::getDisplayName($city)."\""; $hotelsToShow=hotel::getForCity($city); break; } case "region": { if ($select!=all) { $region=$select; $select="region"; } else $region=$select; break; $heading="Hotels for \"".city::getDisplayName($region)."\""; $hotelsToShow=hotel::getForRegion($region); break; } case "province": { if ($select!=all) { $province=$select; $select="province"; } else $province=$select; break; $heading="Hotels for \"".city::getDisplayName($select)."\""; $hotelsToShow=hotel::getForProvince($select); break; } case "all": { $heading=""; $hotelsToShow=hotel::getAll(); break; } } ?>   <script type="text/javascript"> <!--   function formS() { var form1;   form1=document.getElementById("myForm"); form1.submit(); } function myRegion() { var form1;   form1=document.getElementById("myRegion"); form1.submit(); } function myProvince() { var form1;   form1=document.getElementById("myProvince"); form1.submit(); }   // --> </script>       <h2>    Overview of hotels in Mindanao</h2>       Please send additional information or corrections to <a href="mailto:[email protected]">Mindanao Hotels</a> <p> </p> <form id="myRegion" method="get" action="index.php"> <p>      <select name="select" style="width:200px" onchange="myRegion()"> <option value="all">Region</option>   <?php $ForRegion=region::getAllRegion(); if (!isError($ForRegion)){ foreach ($ForRegion as $element => $value) { echo '<option value="'.$value->Region_id.'"'; if ($value->Region_id==@$region) echo ' selected="selected"'; echo '>'.$value->displayName.'</option>'; } } ?> </select> <input type="hidden" name="menu" value="region"></input> </p> </form> <form id="myProvince" method="get" action="index.php"> <p>      <select name="select" style="width:200px" onchange="myProvince()"> <option value="all">Province</option> <?php   $ForProvince=province::getProvinceById($region); if (!isError($ForProvince)){ foreach ($ForProvince as $element => $value) { echo '<option value="'.$value->Province_id.'"'; if ($value->Province_id==@$province) echo ' selected="selected"'; echo '>'.$value->displayName.'</option>'; } } ?> </select> <input type="hidden" name="menu" value="province"></input> </p> </form> <form id="myForm" method="get" action="index.php"> <p>      <select name="select" style="width:200px" onchange="formS()"> <option value="all">All cities</option> <?php $cities=city::getCitiesById($region); if (!isError($cities)){ foreach ($cities as $element => $value) { echo '<option value="'.$value->City_id.'"'; if ($value->City_id==@$city) echo ' selected="selected"'; echo '>'.$value->displayName.'</option>'; } } ?> </select>   <input type="hidden" name="menu" value="city"></input> </p> </form>
