Geonames Les dejo el código... perdon por lo extenso. Probe modificando ws.geonames... por api.geonames... (línea 86,108 y 146) pero no funciono.
Código PHP:

<div id="map_canvas_form"></div>
</div>

<input type="hidden" id="longitude" name="longitude" value="<?=htmlspecialchars(@$item->longitude)?>" />
<input type="hidden" id="latlng" name="latlng" value="<?=htmlspecialchars(@$item->latlng)?>" />
<input type="hidden" id="timezone" name="timezone" value="<?=htmlspecialchars(@$item->timezone)?>" />
