No, it’s not that bad! I do know how to echo / print etc. things in php. I just don’t know, where to put that code. Should I create a new php file or should I modify an existing one. Putting the code on a new wordpress-site or post will not work, I think.

Sorry for the confusion and thank you!

Thanks for your help, but I can’t get it working.

I’m trying to create a list of all orders, ordered by category. Doesn’t matter if it’s a CSV Export or a table on a single page. Maybe there is an easier way to achieve this? Could you please give me another hint?

Thanks in advance!
