  • xili-language plugin provides an automatic selection of language in theme according to the language of displayed post, series of posts, page or articles. If the post is in gaelic, the texts of the theme will be in gaelic if the author checks the post as gaelic and if the theme contains the right .mo file for this target language.

  • A very readable interface with a list of titles (and links) to help you write/edit/modify articles and their translations.

  • To help authoring, current user can choose language of his dashboard.

  • xili-language select on the fly the multilingual .mo files present in the theme’s folder (no cookies, no redirections like “301”).

  • xili-language uses a custom taxonomy to specify language of post, page and custom post. Full compatible with WP JSON REST API

  • xili-language plugin works on WordPress installation in mono (standalone) or on one site belonging to a multisite (network) install.

  • xili-language plugin works on WordPress installation for WebApp with JSON REST API – see changelog because WP JSON REST API 1.2.1 in under full development but yet powerful.

  • As educational plateform in constant changing since 2009, xili-language trilogy tries to use most of the WordPress Core functions and features (Custom taxonomy, API, metabox, pointer, help, pomo libraries, …). The options are adjustable.


According some users, current versions can be stable with recent WP versions. BUT since 2 years, a new version is fully rewritten and tested in few websites. These new versions are available in Github and here in WP repository in tag Advanced View. Your feedback will be very valuable.

Other compatible plugins by xiligroup dev

including xili-language plugin

Please verify that you have installed the latest versions of:

  • xili-dictionary plugin: With xili-dictionary, it is easier to create or update online, via admin/dashboard UI, the files .mo of each language.
  • xili-tidy-tags plugin: With xili-tidy-tags, it is now possible to display sub-selection (cloud) of tags according language and semantic trans-language group (trademark,…).

That this plugin does not

With around 8000 php lines, xili-language is not everything…

  • xili-language plugin does not create additional tables in the database, do not create cookies and only use 4 lines in Options table. xili-language simply makes proper use of the taxonomy tables and postmeta table offered by WordPress to define language and link items between them. Because xili-language plugin does not modify deeply the post edit UI, it is possible to use iPhone / iPod Touch WordPress app to prepare and draft the post.

  • xili-language plugin does not replace the author or the editor. No automatic translation. Content strategist is the master of the languages, the contents and the navigation inside the website. With xili-dictionary, webmaster can translate the theme’s items and when .mo files are in place, xili-dictionary can be deactivated. For design, the creator is free to choose text or graphic. xili-language does not provide flags (or few as example in child-theme example like twentytwelve-xili )!

Newbie, WP user, Developer,…

  • Dear Newbie: originally built for webmaster and developer, the plugin trilogy progress since 6 years to be more and more plug and play for newbies who can read and spend a little time mainly for translation.

  • xili-language is also dedicated for theme’s creator or webmaster with knowledges in CMS and WP and having (or not) tools to create .mo language files. Through API (hook), the plugin add automatic tools (or links or filters) for sidebar or top menus. Categories or Archives lists are translated also.

  • xili-language provides also series of functions which can be hooked in the functions.php file of the theme that you create i.e. for a cms like multilingual website.
