Display Features on Invoices

[MrTino]

Hi all,

 

So, I want to display some features on invoices. I found some other threads with examples on how to do so. But, when I tried it, I am always getting an empty array. 

Here is my code:

{assign var="features" value=Product::getFrontFeaturesStatic($conf.pdf_id_lang, $order_detail.product_id)}
{$features|@debug_print_var} 

All I get is "Array (0)"

So, I noticed "$conf.pdf_id_lang" is no set. It returns NULL.

If I manually enter 1 or 2 it works.

Any idea in which variable I can get the language of the invoice?

Thanks!

Where and how have you used that snippet? It looks like a M4 PDF Extensions code.

Thanks for the answer.

I think you are right, used the code without reading the thread and didn't notice it was from an addon.

I'll have a look at your addon!

Thanks,
