Amaury Balmer

A plugin for WordPress that allow to translate any post type in another languages.
The user features can be summarized in the ability to switch between multiple languages and on the single view of content. Thus, a page can be translated in X languages.
The architecture chosen for development is fully consistent with WordPress 3.0, we created a content type translation, and we created a taxonomy for the site languages. 
We customized the WordPress admin console to provide the translation functionality, a bit of AJAX to make the convenient interface. Finally, we created a widget that displays the languages available for the currently loaded content.
A translator role is automatically created with the plugin, it allows a user to this role only to create and manage translations.
The plugin offers settings:
<ul>
<li>Automatic insertion of languages available to the end of the article</li>
<li>Language detection URL : via a “lang” parameter in the address or via a prefix beginning of the address:
<ul>
<li>http://www.herewithme.fr/contenu/?lang=de</li>
<li>or http://www.herewithme.fr/de/contenu</li>
</ul>
</li>
<li>Enabling translations on their choice of post types</li>
<li>2 modes for the translation mechanism, which I will explain in FAQ.</li>
</ul>
