Default Value for Event Venue?

You could try adding something like this to the functions.php of your theme:

function wpt_event_venue( $venue, $event) {
  if(empty($venue)) {
    $venue = 'My default venue';
  }
  return $venue;

}
add_filter('wpt_event_venue', 'set_default_venue', 10, 2);

Thanks for the reply Jeroen but that code within my functions file does not seem to be doing anything unfortunately….
