Why does this work to remove a single term?

$existingTerms = wp_get_post_terms($postID, 'custom_taxonomy');
        $newTerms = array();
        foreach($existingTerms as $term) {
            if ($term->slug != 'remove_this_term') {
                $newTerms[] = $term->term_id;
            }
        }
wp_set_post_terms($postID, $newTerms, 'custom_taxonomy');

But this doesn't?:

wp_remove_object_terms($postID, 'remove_this_term', 'custom_taxonomy');

Am I misunderstanding what wp_remove_object_terms does?

  • Should work as expected. Did you notice the two terms differ in the set and remove function? You added a s. So maybe you get early returned by wp_remove_object_terms. Apr 1, 2018 at 8:19
  • That was just a test variable sorry. In my real code both are the same

    If the term argument is a string it is interpreted as the term slug. Use integers for ids. Apr 1, 2018 at 16:39

I know this is old but I ran across this issue, adding true to the end of the hook resolved the issue. In this instance wp_remove_object_terms($postID, 'remove_this_term', 'custom_taxonomy', true); will run the hook.

    It doesn't have a fourth parameter. I believe their term_id was a string, not integer.

  • Just would like to add my two cents, even tho wp_remove_object_terms documentation state string|int|array $terms that isn't true. Only int are permitted when using ids. wp_remove_object_terms((int)$postID, (int)$termID, 'custom_taxonomy'); Mar 23 at 13:34
