Breaking: #23736 - Page Language detection set earlier in Frontend Request Process¶
Previous TYPO3 sites without Site Handling
used TypoScript conditions like
[globalVar = GP:L = 1] to switch
between languages. For this, TYPO3's Frontend Request Process needed a parsed TypoScript before
doing the language overlay of the currently visited page.
This made it impossible to use conditions for accessing the translated page record like
[page["nav_title"] == "Bienvenue"],
which was a long outstanding conceptual issue that was finally made possible through Site Handling.
Now, the translated page is resolved directly after the actual page and rootline resolving.
The translated page record (based on the fallback handling in the
Site Configuration) is now available in
$TSFE->page at a much earlier stage of the Frontend Request process.
This means, TypoScript conditions based on the page record (see example above) might be different.
In addition, the two hooks
are called earlier, no TypoScript is available yet.
TYPO3 installations with custom extensions using the hooks mentioned above or that have language-specific "page-based" conditions.
Review the hooks or use a PSR-15 middleware to use the same place to extend TYPO3's Frontend Request process after TypoScript was initialized.
Also, be sure to review any of the TypoScript conditions (possible
Web->Template module) if they are related to values only
available in the default language, which seems to be a very rare case however.
