I require the taxonomy title to be hidden if there are no posts associated with it.

Here is my code:

  • I must misunderstand because the default hide_empty argument for get_terms is to not show terms without posts associated with them. – s_ha_dum Commented Apr 4, 2014 at 0:22
  • I know, thats what I thought but it is showing them?? – user49899 Commented Apr 4, 2014 at 0:23
  • Perhaps a plugin or your theme has added a filter? You can try explicitly setting that argument though that is a long shot. – s_ha_dum Commented Apr 4, 2014 at 0:25
  • I have tried.. $wine_type_terms = get_terms( 'wine-type', array('hide_empty' => 1)); – user49899 Commented Apr 4, 2014 at 0:28
