UPDATE
Big thanks to Coen who updated a few things — for example, meta.php will be hook-able. Awesome. I will be using his solution.
Thanks to helgatheviking for reminding me about attributes and for explaining that they were taxonomies.
I still don’t like bacon… some of your google posts came in handy though. Great work.
Thanks to royo for reminding me that I need to read more and your overall support is appreciated. I am going to say something silly now: “you guys don’t want me to start learning codes — else you will be out of work — seriously — I would be THAT good!!!” Hey I am joking, take it easy… ?? I’ll keep doing what I do best… nuthin… niente. I only read adult magazines with pictures, NOT.
For those interested;
My working solution was to use a plugin called GD Custom Posts And Taxonomies Tools, which allowed me to create new WC taxonomies properly, and I’d call them manually in meta.php.
If you feel rich (or broke, doesn’t matter really…), say thanks to Coen.
PS: did I tell you about the guy with the dog?
