Bug #100030

Translation handling: Fallback chain is broken if backend user is logged in.
100%
Description
According to https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ApiOverview/Localization/XliffFormat.html TYPO3 supports a fallbackchain for locallang.xlf files with region-specific prefix.
As I understand correctly the feature SHOULD work this way:
If I have a locale of e.g. de-DE.UTF-8 TYPO3 will use the language labels in de_DE.locallang.xlf. If this file does not exist the label from de.locallang.xlf will be used. And last but not least the original label from locallang.xlf comes into effect.
This behaviour is broken in 12.2.0
If a BE user is logged in and uses the Backend (!) with german translation, the file 'de_DE.locallang.xlf' is ignored when rendering the frontend! (thanks for the acceptance test in our project which has detected this error ;)
If no BE user is logged in, the file de.locallang.xlf is ignored.
So, as a temporary workaround I have a symlink de.locallang.xlf which points to de_DE.locallang.xlf to tackle both use cases.
I expect this bug is related to vendor/typo3/cms-extbase/Classes/Utility/LocalizationUtility.php
/**
* Resolves the currently active language key.
*/
protected static function getLanguageKey(): string
{
if (($GLOBALS['TYPO3_REQUEST'] ?? null) instanceof ServerRequestInterface
&& ApplicationType::fromRequest($GLOBALS['TYPO3_REQUEST'])->isFrontend()
) {
// Frontend application
$siteLanguage = self::getCurrentSiteLanguage();
// Get values from site language
if ($siteLanguage !== null) {
return $siteLanguage->getTypo3Language();
}
} elseif (!empty($GLOBALS['BE_USER']->user['lang'])) {
return $GLOBALS['BE_USER']->user['lang'];
}
return 'default';
}

Hi Marc,
just to get this right... you have a be_users, which logs into the backend, and you expect this user to get the labels from "de_DE.locallang.xlf" but it does not respect that?
So my question would be... does you backend user record contains the value "de_DE" in the "lang" field?

Hi Benni,
Please see attached screenshot. I have a label in the frontend ("to top", "nach oben") which is delivered by a f:translate-VH in the page layout. I expect that this label is chosen according the language which is used in the frontend. In both cases this is german, which is configured as de_DE.UTF-8 in the sites configuration).
In the left part of the screenshot I am logged in as BE user (with language de), in the right part it's an anonymous browser without logged in BE user. As you can see in the one case (BE user logged in with german backend) I get the translated string; in the other the original string from locallang.xml.
I expect that the BE user and it's chosen backend language is not affected to the frontend translation, but it is.
In this case we have had v11 TYPO3 (now updated to 12.2) with the respecting translation files (locallang.xlf and de.locallang.xlf) which is also sufficient for this website. But I have to copy/symlink de.locallang.xlf to de_DE.locallang.xlf to get the translated string "nach oben" in both cases (BE user is logged in//BE user is not logged in).
If you have further questions, I'm happy to help.

I would go even further and would not expect the configured backend language of the user to affect the frontend language (especially not only of f:translate) at all!
Regarding the fallback chain I would expect the system to try de_DE.locallang.xlf, if not present de.locallang.xlf, if not present locallang.xlf.
This would allow us to have language versions of the website like de_DE, de_AT and de_CH and only require a de.locallang.xlf which might get overrides from files like de_CH.locallang.xlf if a label needs to be overridden for that language version.

That was my exact intention (and I wonder why it's not working).

Is there any more feedback needed (aka "is the ticket status correct")?

Hi Marc,
so I had a quick look at your issue.
I can see that my frontend (v12.3-dev) also returns "de" but this is because my site configuration contains a "typo3Language: de" setting. If I remove this, it worked. Can you recheck this, also with the latest v12.3 status?
