We have a multi language website and would like to have the pdf vm invoice in the different languages (german and french) (virtuemart and joomla configuration is ready for multi language)

How can we do this exactly? We didn't understand the documentation and couldn't find any solutions in the forums.

In invoice template -> Help we found this:
"You can enclose language strings by square brackets to be translaed, and even specify language file which have to be loaded (e.g.[com_content:Article])."

Can you explain and give us an example?

thanks

Hello. Currently we translate automatically everything possible from VirtueMart and language strings. You want certain blocks of text be different for every language? We added this option to latest 2.0.38 release, when you can use conditional blocks in template, like that:

{if document_language == "fr-FR"} this is french text {/if}
{if document_language == "de-DE"} this is german text {/if}

As for document language, defaultly it is generated in "order language" field, that was added in some VirtueMart version ago. See related settings in VM Invoice => Global Configuratipon => Page Appearance.

Edit: When you use in template

[SOME_LAGUAGE_STRING:com_componentname]

, Joomla translation files will be used for translation of this string. Defaultly that function is used for various captions on invoice, but you can specify your own (for example by using Joomla Language Override function)
