Description

I tried to update the language packs and got this PHP error:

Fatal error: Cannot use string offset as an array in typo3/sysext/lang/Classes/Controller/LanguageController.php on line 208

The problem occurs, if the languagePackIndex is empty (see http://ter.rz.tu-clausthal.de/ter/c/o/core-l10n/core-l10n.xml for example):

<?xml version="1.0" standalone="yes" ?>
<TERlanguagePackIndex>
    <meta>
        <timestamp>1348788881</timestamp>
        <date>2012-09-28 01:34:41</date>
    </meta>
    <languagePackIndex>
    </languagePackIndex>
</TERlanguagePackIndex>

The problem is in the XML parser in TYPO3\CMS\Lang\Utility\Connection\Ter::parseL10nXML($string). It will fill the tag with a string containing the space / linebreaks between the two languagePackIndex XML tags. The isset() check in TYPO3\CMS\Lang\Controller\LanguageController::checkTranslationForExtension($languages, $extensionKey) therefore returns TRUE which results in the error above.

Note: The problem is already solved in the new language module in TYPO3 version 6.0. See http://forge.typo3.org/issues/39963.

Hi Kai,

thanks for the reply.

I'm using the lang module in the current master (all submodules updated) and I'm getting this error.

Am I using the newest version or is it available somewhere else?

Kind regards,
Alex

Hi Kai,

OK, the patch fixes the issue.

I'm a bit unsure if I should abandon my patch because in my eyes it solves a general problem in the XML parser (TYPO3\CMS\Lang\Utility\Connection\Ter::parseL10nXML($string)) with handling empty tags.

When you think it is obsolete you can close the issue and I'll abandon the patch.

Kind regards,
Alex.

The problem is that the functionality has changed. A check with "isset()" now returns FALSE because the value will never been set if it's empty or contains only spaces. It is necessary to make sure that nothing gets broken with this change.

Hi Kai,

I just did a quick search through the files. It seems \TYPO3\CMS\Extensionmanager\Utility\Connection\TerUtility\Ter::fetchTranslationStatus() is only used in the LanguageController (in the current master with the patch for #39963 applied). This method is the only one that uses the parseL10nXML() method.

Kind regards,
Alex
