 * I am redoing a google widget wordpress directions with version 3. But while doing
   it I wanted to not have to have someone enter the latitude and longitude of address
   and just use a geo-code call off of the address. Now I only want to call the 
   geocode when the wordpress widget is updated but am having a hard time finding
   out if I can do it. I figure I could just pass the instance through a function
   before updating like below.
    function update($new_instance, $old_instance) { 
   $coords = gmap_geocode($new_instance[‘address’]); $instance[‘address_longitude’]
   = strip_tags(($coords[‘long’])); return $instance; } With gmap_geocode function
   returning the long and lat in a array and then putting the information into an
   instance saved to display on the widgets front end. Is this capable or should
   I just run the geocode every time on the front end? I don’t think that would 
   be best.
