What can this extension do?[edit]

If supplied with location data it will return a JSON stream of various weather data. This extension creates the tag <wunderground>...</wunderground>, it takes various arguments e.g <wunderground arg="somewhere"> This arg can then be used to push to wunderground to return weather data based on this location.

See http://www.wunderground.com/weather/api/d/documentation.html for specifics of what you can push to wunderground.


In this case I am using ICAO codes for airport data, this is passed to wunderground as non ambiguous location data. Cities, Lat/Long and others can also be used. See Docs above and note slight change of URL ebing called. " /q/"airport" vs "/q/STATE/CITY"

NOTE: the Wunderground API has been discontinued, thus making this extension non-functinoal.
YOU WILL NEED TO APPLY FOR AN API KEY. It takes 2 minutes and is free. Here
