I'm trying to output links to custom taxonomy assigned to a single post on a single post page. I've tried other thing but get errors. This is the closest I can get. It just needs to find the terms for the current post instead of outputting all terms of a taxonomy.

    $term_id = 6;
    $taxonomy_name = 'categories';
    $termchildren = get_term_children( $term_id, $taxonomy_name );
        foreach ( $termchildren as $child ) {
        $term = get_term_by( 'id', $child, $taxonomy_name );
        echo '<a href="' . get_term_link( $child, $taxonomy_name ) . '">' . $term->name . '</a> ';

@Howdy_McGee I tried the following code, where 'adoption-status' is a term for the custom taxonomy 'categories'. I'm looking for children of 'adoption-status'. It doesn't output anything. No errors either.

<?php get_the_terms( $post->ID, 'adoption-status' ); ?>

The following code almost works but displays all 'categories' of the current post, not just those of the term (or sub-category) 'adoption-status'

<?php echo get_the_term_list( $post->ID, 'categories', '', '', '' );?>
  • I think what you're looking for is get_the_terms(): codex.wordpress.org/Function_Reference/get_the_terms

  • Yeah, I tried that already but doesn't work. Commented Feb 19, 2015 at 16:24
  • @TroyTempleman what was the output that didn't make it work? Could you post your implementation?

  • Could you possibly edit your question with the implementation you tried? Michelle is right, get_the_terms is usually the best bet for what you need.

    @Howdy_McGee OK. To clarify, this is for a single post page. There are categories for each post (a custom taxonomy, not built in post categories). One of the categories is "Adoption Status", which has a few "sub-categories". I want to display which one of these sub-categories is selected for each post. Commented Feb 19, 2015 at 17:41

I hope I understand your question. You are looking for all terms connected to a single post, but only terms that are children to the adoption-status term

To get all the terms from a specific post, you can make use of wp_get_post_terms(). This will return all the terms of a specific taxonomy connected to the post.

You will also need to make use of get_term_children() to get all the child terms from your adoption-status term

Once you have all that, it is simply to compare the two, and only returning the terms that are associated with the post and is a child term to your given term.

You can try something like the following (NOTE: Change the term ids and taxonomy names accordingly)

$child_terms = get_term_children(21, 'category');
$all_terms   = wp_get_post_terms($post->ID, 'category');

foreach ( $all_terms as $term ) {

    if( !in_array($term->term_id, $child_terms ) ) 

    echo $term->name;

  • I tried changing the term id and taxonomy name to $child_terms = get_term_children(6, 'categories'); but get an error. Commented Feb 19, 2015 at 17:48
  • What error. You should change taxonomy in wp_get_post_terms as well. Most probably because the taxonomy don't exist Commented Feb 19, 2015 at 17:59
  • Pieter, I changed that too 'categories' also but get the error "Parse error: syntax error, unexpected T_ENDIF"? Commented Feb 19, 2015 at 18:04
  • My bad, I had an extra if statement left in there by mistake. I take it out and get nothing, and no error. Commented Feb 19, 2015 at 18:07
  • Recheck your code and ID's. On my installation, I have a child term and a grandchild term which belongs to term 21. With this code, only the child term and grandchild term are retrieved Commented Feb 19, 2015 at 18:11
