dynamically loading cities.

Copy linkTweet thisAlerts:
Jun 14.2005

Hi, I’m looking to make a page that dynamically loads cities into an option field according to the country/state selected on the same page. Is there anyway to do this without using javascript? All of the cities/states are stored in a database. A tutorial would be greatly appreciated. Thanks for any help.

@NogDogJun 14.2005 — If you want the cities to populate without submitting the page to do the processing, then you'll have to use some sort of client-side technology, whether it be Javascript, Java applet, Flash, etc.

@FirEwAteRauthorJun 14.2005 — I would like to be able to use something like this:
[CODE]function loadState(id) {
var s;

var stateName;
var cstate = new Array();

if(id==2){
<? //get states list from database
$sqlState="select * from ae_states where country_id=2 order by state_name ASC";
$reState=mysql_query($sqlState);
$sct = mysql_num_rows($reState);

$k=0;
while($rowState = mysql_fetch_array($reState)) { ?>
s=<?=$k?>;
stateName='<? echo $rowState["state_name"]; ?>';
cstate[s]=stateName;
<? $k=$k+1;
} ?>

var len = cstate.length;
cstate[len]="All states";
var field2 = document.frm_advSearch.asrch_state;
for(j=0; j<len+1; j++){
newOpt=cstate[j];
field2.length=j+1;
field2.options[j]= new Option(newOpt,newOpt);
}
} [/CODE]

But make the where clause dyncamically select using the id parsed from the country option input.

Success!
