Help with ComboBox, datasource from database

Question

Hi there,
i am new to Flex technology and desperately need help with
combobox.
I have a combobox in my app and the datasource comes from
MySQL database. I use a PHP script to populate the combobox. Say in
the datatabse table, I have the following result:
id name
1 dog
2 cat
3 horse
In the app, the combobox will have the list as the name of
the animals: dog, cat, horse. But when the user selects dog, how do
I get the selected id 1 instead of the label "dog".
Any help/suggestion will be appreciated.

Answer 1

Hi again,
the xml for the combobox datasource is as follows
<animals>
<animal>
<id>1</id>
<name>dog</name>
</animal>
<animal>
<id>2</id>
<name>cat</name>
</animal>
<animal>
<id>3</id>
<name>horse</name>
</animal>
</animals>
and my <mx:HTTPService> is:
<mx:HTTPService id="dropDown" useProxy="false" url="
http://localhost/~ronnyk/combobox.php"
resultFormat="e4x" result="get_drop_down(event)" />
public function get_drop_down(e:ResultEvent):void{
var dropArr:XML = e.result as XML;
cb.dataProvider = dropArr.animal;
cb.labelField = "name";
cb.data = "id";
public function clickme():void{
txtinput.text = cb.selectedItem as String;
I can't figure out which part I did wrong, in order to get
the id instead of the name when the user clicks the button
