in HTML before/after fields

Hi,

I’d like to find an elegant method of sending parameters to my functions.php file, just by changing settings from within the widget’s backend interface.

I was thinking of adding an <input type=”hidden” name=”xxxx” value=”yyy”>, and then get it via $_POST method, but it seems that it is somehow filtered out, because it doesn’t appear when I inspect the resulting html.

Text and other html tags (, <div>…) are working OK.
