I used the Tax-meta-class by bainternet but i still can’t get it to display any of the results.

There’s a slight catch to using bainternet’s Tax Meta Class: the way you save and retrieve data changes depending on your WordPress version.

If you are using the latest version of WordPress then use
get_term_meta instead of get_tax_meta.

I believe the exact version is WordPress 4.4.

  • If your WP version is before 4.4, use get_tax_meta.
  • If you are 4.4 and above, use get_term_meta.
