This module provides support for internationalization of Drupal sites in various ways:
- Translation of the user interface for registered and anonymous users
- Multi-language for content, combined with url aliasing. For this feature to be used, you must enable it in the module configuration and then use url aliasing to keep pages in various languages. I.e. 'en/mypage', 'es/mypage' should be English and Spanish versions of the same page
- Detection of the brower language
- Keeps the language settings accross consecutive requests, using a number of methods: URL rewriting, sessions, cookies
- Provides a block for language selection and two theme functions: i18n_flags and i18n_links
For url rewriting you need to have the file i18n.inc in the includes folder and add the following line to your configuration file:
include 'includes/i18n.inc';
You can try different settings to have only content translation, interface translation or both.
