Four steps to add a new language to a Sulu website
Multilingual Websites - Step 1

Add one line of XML to add a new language, and one more to set up the URL structure

Each locale is defined by a developer in XML. Sulu’s neatly organized approach keeps configuration out of the database, which makes it much easier to deploy in different environments and keep track of changes. It also simplifies exchanging data between different environments — a true time-saver when testing with real content.

Multilingual Websites - Step 2

Frontend developers can create a language switcher in Twig with one straightforward variable

Sulu passes all available localized URLs as the “localizations” variable. From there, developers can work with Twig — a mature, well supported templating language from the creator of the Symfony framework.

Multiportal and Multisite - Step 3

Editors start managing content

Once you’ve set up a language, Sulu’s intuitive administration interface has everything your editors need to manage multilingual content with ease, and work seamlessly across locales. They can define non-translatable fields, which is useful for content such as images that are not language-specific. Similarly, shadow pages offer fallbacks for when a piece of content doesn’t exist in one or more languages. Editors can store assets and snippets centrally and use them across webspaces and locales so they don’t have to duplicate content and maintain many copies.

Multilingual Websites - Step 4

See the page content at the correct URL

Once your locale is set up and your content entered, Sulu takes care of many details. These include canonical URLs — which can be set automatically or manually — and a sitemap showing all localization variants, so search engines index your site favourably. Web pages are rendered using the widely adopted, reliable Twig templating language for excellent developer experience and productivity.
