I hope someone can help me.

  • I have a custom post type called Site members with slug site-members
  • I have a custom field (which is a select field) called aab-ew-select-visible and in this field users can select either of the options display or hide
  • The taxonomy slug is test-all-members-cpt-tax
  • The term slug is test-all-members-ew-tax

Whenever anyone posts a new post to this custom post type, they can choose to either 'hide' or 'display' a section of their post on the website. If they choose to 'display' with the select field, then they should automatically be assigned to the taxonomy term 'test-all-members-ew-tax' mentioned above.

If anyone can help with the code for this, that would be massively appreciated.

Thank you for your time, Andrew

The following should do what you need:

add_action ('save_post_site-members', 'add_term') ;

add_term ($post_id)
    if (defined ('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
        return ;

    $meta_key = 'aab-ew-select-visible' ;
    $tax = 'test-all-members-cpt-tax' ;
    $term_slug = 'test-all-members-ew-tax' ;

    $meta_value = isset ($_REQUEST[$meta_key]) ? $_REQUEST[$meta_key] : '' ;
    if ('display' == $meta_value) {
        $term = get_term_by ('slug', $term_slug, $tax) ;
        if ($term) {
            wp_set_object_terms ($post_id, $term->term_id, $tax, true) ;

    return ;
  • Thanks so much @Paul - but for some reason that hasn't worked either. I just created a new post, selected 'display' as the value of the field, and the term wasn't assigned on saving the post. Do you know anywhere I could be going wrong? I really appreciate your time - thank you. Feb 18, 2017 at 16:45
  • I just edited my answer, with a more direct way of setting $meta_value. The original code assumed that you had some other func that hooked into save_post-site-members that was storing the meta...and if the func I wrote was being called before that other func then it wouldn't work. The revised code should be fine. Feb 18, 2017 at 17:06
  • Thanks for updating the code. I just ran it again, then created a new post, and still it didn't work. Feel cursed Feb 18, 2017 at 17:19
  • I've tested (both versions of) my code and it works in a test env I have. So, seeing a little bit more of your code would be helpful in figuring out why it's not working for you. Feb 18, 2017 at 17:26
  • You might also try writing $meta_value & $term to a log file so that you can see what their values are when the save_post action is fired (i.e., maybe that term doesn't actually exist). Feb 18, 2017 at 17:29
