Common functions that many Drupal modules will need to reference.


function entity_language($entity_type, $entity) {
  $info = entity_get_info($entity_type);

  // Invoke the callback to get the language. If there is no callback, try to
  // get it from a property of the entity, otherwise NULL.
  if (isset($info['language callback']) && function_exists($info['language callback'])) {
    $langcode = $info['language callback']($entity_type, $entity);
  elseif (!empty($info['entity keys']['language']) && isset($entity->{$info['entity keys']['language']})) {
    $langcode = $entity->{$info['entity keys']['language']};
  else {
    // The value returned in D8 would be LANGUAGE_NONE, we cannot use it here to
    // preserve backward compatibility. In fact this function has been
    // introduced very late in the D7 life cycle, mainly as the proper default
    // for field_attach_form(). By returning LANGUAGE_NONE when no language
    // information is available, we would introduce a potentially BC-breaking
    // API change, since field_attach_form() defaults to the default language
    // instead of LANGUAGE_NONE. Moreover this allows us to distinguish between
    // entities that have no language specified from ones that do not have
    // language support at all.
    $langcode = NULL;

  return $langcode;


Note that this method was apparently added in D7.15 and is not available in earlier releases of D7. Use with caution in contrib code!
