Tips & Tricks

Do not use flags for the language selection
Using flag icons for languages is a very bad idea. Flags represent countries and not languages. Not every language belongs to only one country! Would you take the American flag, the British flag or the Australian flag for English? What flags do you use for Chinese Simplified and Chinese Traditional (two different forms of writing for the same Chinese language)?

Use a select menu for language selection
Easy: go to your front end module settings and select nav_dropdown in the Navigation template option. BAM!, you're done :-)
Customizing alternate link tags
By default, ChangeLanguage will add <link rel="alternate"> markup to your page's head section. This will tell Google and other search engines which pages belong together for better search results.

If you want to customize the alternate tags, you can create a copy of the block_alternate_links.html5 template and customize the output.

Common issues

"You must not have more than one auto_item parameter" error message
This error is a misconfiguration based on all of the following conditions:
  1. You do have auto_item functionality enabled in the system settings.
  2. Multiple modules (e.g. news and events) have the same Redirect page set.
  3. There are news and events with the same alias.
To fix the error message, you must correctly set up your page structure and modules.

Frequently Asked Questions

Where can I get support for ChangeLanguage?
Please use the official Contao community forums at https://community.contao.org for support on all our free extensions.
I have found a bug, where do I report it?
Please use the GitHub issue tracker to report bugs. Please make sure to first check if the problem has already been reported.
I need feature X, can you add that?
It depends. You can use GitHub issues to create feature requests. If your business depends on the feature, it's best to pay a developer to implement it for you and then give something back to the community. Make sure to read our Open Source manifest on this topic.
How can I add localization for my native language?
Translations for ChangeLanguage are managed on Transifex. To add your language, simply register yourself for the ChangeLanguage project and add the new language. New localizations will be published with each new release by default.

Known limitations

  • The option in Contao 3.5 to disable the use of page aliases (tl_settings.disableAlias) is no longer supported.
