form_translator

This extension provides a backend module for translating TYPO3 form framework forms and a cli for creating a source xliff file for a given form.

Installation

Either from TYPO3 TER or through composer $ composer req r3h6/form-translator.

Integration

If you like use machine translation by LibreTranslate you must only configure an api host in the extension configuration. See available mirrors.

How it works

The extensions adds a translation file path to the *.form.yaml file when localize through the backend module.

# example.form.yaml
renderingOptions:
  translation:
    translationFiles:
      99: fileadmin/form_definitions/l10n/example.xlf

Customized validation error messages are translated by overriding the form definition at runtime using the afterBuildingFinished hook from the form framework.

Upgrade

From v2 an TYPO3 v12

Rename language files prefixed with a locale like de_DE.locallang.xlf to the corresponding TYPO3 language de.locallang.xlf or setup a custom language.

From v2 an TYPO3 v11

No changes required.

Known issues

• Issues on GitHub

Transalte to English overrides the original form labels

Scenario: German is used as default language and your form definition labels are in German too.

When you translate a form to English, English will override your original labels even on the German version of your site.
You have following options:

1. Create a (duplicated) German translation of the form
2. Add the English locale without charset to the extension configuration typo3LanguageWhitelist

Background: Beginning with v12, TYPO3 uses the locale configured for the site to determine the language.
For English, TYPO3 uses the file named xyz.xlf, it does not load a file named en.xyz.xlf, but it does for en_US.xyz.xlf.

Please note: I will not include other translation api's than LibreTranslate in this extension. If you need an other service, you can create your own by implementing TranslationServiceInterface.
