mooc7 field_available_languages($entity_type, $field)

Collects the available languages for the given entity type and field.

If the given field has language support enabled, an array of available languages will be returned, otherwise only LANGUAGE_NONE will be returned. Since the default value for a 'translatable' entity property is FALSE, we ensure that only entities that are able to handle translations actually get translatable fields.


$entity_type: The type of the entity the field is attached to, e.g. 'node' or 'user'.

$field: A field structure.

Return value

An array of valid language codes.
