[Typo3-dev] getting values from locallang_db.php for frontend output

[Thorsten Kahler]

Hi Joey,

t3lib_div (and some other t3lib classes and objects, e.g.  
$GLOBALS['TYPO3_DB']) are available in the FE, of course, since they're  
needed there also.

Back to you problem:
tslib_fe::readLLfile() uses t3lib_div::getFileAbsFileName() to get the  
real filename. You can use tslib_fe::readLLfile() the way you want to, but  
you have to put the extension key after "EXT:". Something like

$labels =  
$GLOBALS['TSFE']->readLLfile('EXT:some_extension/locallang_db.php');

should do.

But in your OP you asked for the "preferrable way" to include LL labels.  
When I looked at tslib_fe I also found (just before readLLfile()) the  
function tslib_fe::sL(). It does the same for FE as language::sL() does  
for BE. $GLOBALS['LANG'] is one of the classes/objects that's not  
available in FE, but some of it's functionality is realized in tslib_fe.  
The syntax for the label key is similar to the syntax used for "title" in  
the "ctrl" section of $TCA [1]. The contents of every file that's opened  
by tslib_fe::sL() are cached so there's no performance issue. Additionaly  
this function also takes care of charset conversion.

IMHO the "preferrable way" is to leave the label management to the core  
and use tslib_fe::sL() like

$label =  
$GLOBALS['TSFE']->sL('LLL:EXT:some_extension/locallang_db.php:label_key');

Regards
Thorsten

PS: I should keep this in mind for my extensions, too ;-)

It's not a bug - it's an undesired feature.
