I’m am looking to add the the custom fields to my installation, and I found this code in the “tips” section.
1) Can you clarify where this code needs to be added?
2) It appears this is several years (and versions) old. Is this still correct with the latest version?
You have to add this code to you theme’s functions.php file. Please note this require at least moderate knowledge about PHP language.
Yes, that snippet are still relevant.
