I see all these custom fields below the WordPress editor, and I know there are plugins to make use of them, but what do they do and how could I use them?
It’s been a while since anyone’s asked about Custom Fields! Here’s an older tutorial that should cover the basics. There’s also a link to download a PDF from that page, which includes much more detail.
Hope this helps!
I watched it that explains it. Now I have to see how I can use that. And how ACF can be tweaked to do what I need.
