How output field in $view->result?
Views rows and entities are objects so I would think it should be this:

$view-&gt;result[0]-&gt;_field_data['nid']['entity']-&gt;event_calendar_status[LANGUAGE_NONE][0]['tid'];


but I'm guessing a little bit.

Also note the use of quotes in the array keys and the use of the LANGUAGE_NONE constant instead of 'und' for the field language.

If you still have trouble then try using the Devel module to see the structure of the view object variable.

There is information available via Google for how to use the Devel module to debug.
