How to pass userpref variables in an igoogle widget

Hi I've made my igoogle app simple though it is basically using an xml/php file and getting a series of articles and displaying them. Simple and nice.

Now I just need to finish it off with passing how many stories the use would like to sh开发者_如何学Cow. I've got the dropdown working for when they click edit settings in the google area but I'm at a loss on how to pass the information back to my php/xml file and display the number of stories the user has selected.

Can anyone help.

do a <form>

with auto-submit

<select name='myfield' onchange='this.form.submit()'>
<option .... >
...
</select>
</form>

then you got $_POST['myfield']
