# Deprecation: #100721 - Label-related methods and arguments {#deprecation-100721-1682333511}

See [forge#100721](https://forge.typo3.org/issues/100721)

## Description {#description}

The method `\TYPO3\CMS\Core\Localization\LanguageService->getLL()` has been
marked as deprecated.

Along with the deprecation the method
`\TYPO3\CMS\Core\Localization\LanguageService->includeLLFile()` has been
marked as internal, as it is still used in TYPO3 Core for backwards-compatibility
internally, but not part of TYPO3's Core API anymore.

With the introduction of [Locales](https://docs.typo3.org/permalink/changelog:feature-99694-1674552209), it is also now not recommended anymore to use
custom alternative language keys.

For this reason the argument "alternativeLanguageKeys" of the
`<f:translate>` ViewHelper has been deprecated as well, along with the
method argument of the same name in
`\TYPO3\CMS\Extbase\Utility\LocalizationUtility::translate()`.

## Impact {#impact}

Calling the method `\TYPO3\CMS\Core\Localization\LanguageService->getLL()`
will trigger a PHP deprecation warning.

Calling `\TYPO3\CMS\Extbase\Utility\LocalizationUtility::translate()` with
the argument "alternativeLanguageKeys" will also trigger a PHP deprecation warning,
which is the underlying deprecation warning when using the argument
"alternativeLanguageKeys" of the `<f:translate>` ViewHelper.

## Affected installations {#affected-installations}

TYPO3 installations within backend modules using the method `getLL()` or
extensions or templates using the translate methods.

The former usually happens in extensions which have been migrated from older
TYPO3 versions with legacy functionality in backend modules along
with `$GLOBALS['LANG']` as `LanguageService` object.

## Migration {#migration}

It is highly recommended to use the full path to a label file along
with the `sL()` method of `\TYPO3\CMS\Core\Localization\LanguageService`:

Before:

```php
$GLOBALS['LANG']->includeLLfile('EXT:my_extension/Resources/Private/Language/db.xlf');
$label = htmlspecialchars($GLOBALS['LANG']->getLL('my_label'));
```

After:

```php
$label = $GLOBALS['LANG']->sL('LLL:EXT:my_extension/Resources/Private/Language/db.xlf:my_label');
$label = htmlspecialchars($label);
```
