I am trying to populate a drop down box depending which county has been selected the second drop down should populate with the provinces of the chosen county.



I don't understand why the second dropdown is not populating. I am getting a JSON response in the console so the PHP is correct. I am sure it is something silly but I just cant see it. Thanks in advance.

I'm not overly familiar wit jQuery but it seems you need to parse the response using JSON.parse ( or native jQuery method ? ) and then you ought to be able to access the data OK. The following might point you in the right direction - or it might not as it is not tested...



<script>
$( document ).ready( function ()

$( "#country" ).change( function ()
var countryid = $( this ).val();

$.ajax(
url: 'getUsers.php',
type: 'POST',
data:
countryid: countryid
,
dataType: 'json',
success: function ( response )
var json=JSON.parse( response ); /* PARSE the data */
$( "#province" ).empty();

for( var i in json )/* access using object notation */
var obj=json[ i ];
var id=obj.provinceid;
var name=obj.provincename;

$( "#province" ).append( new Option(id,name) );


);
);
);
</script>
