is there somewhere a manual or howto which describes how to extend the language array for the backend?
i tried to implement my own module and use the oxid translation files. i added a new file to the directory
/out/admin/de/modulename_lang.php
but the script ignores a new file in this directory.
I’m adding new admin languages in format suggested by the OP (modulename_lang.php) but adding them under the ‘modules’ directory and I haven’t had any problems.
Using cust_lang is not not a good work-around IMHO. As soon as you have more the one extension, you don’t want to be stuck sharing that one cust_lang file across multiple projects.
