Im using the following code to get an array of children taxonomies and write them out with links in an unordered list.
<?php
$termID = 10;
$taxonomyName = "products";
$termchildren = get_term_children( $termID, $taxonomyName );
echo '<ul>';
foreach ($termchildren as $child) {
$term = get_term_by( 'id', $child, $taxonomyName );
echo '<li><a href="' . get_term_link( $term->name, $taxonomyName ) . '">' . $term->name . '</a></li>';
}
echo '</ul>';
?>
What I’m trying to achieve is to get the actual term (category) id so I can replace it on $termID and don’t have to hardcode the id of the term.
Any help would be kindly appreciated!
Thanks!

Here is a function I use to list subterms:
/**
* Lists all subentries of a taxonomy.
*
* @return void
*/
function ttt_get_subterms( $args = array () )
{
if ( ! isset ( get_queried_object()->taxonomy ) )
{
return;
}
$options = array (
'child_of' => get_queried_object_id()
, 'echo' => 0
, 'taxonomy' => get_queried_object()->taxonomy
, 'title_li' => FALSE
, 'use_desc_for_title' => FALSE
);
$settings = array_merge( $options, $args );
$subtermlist = wp_list_categories( $settings );
// Without results WP creates a dummy item. It doesn't contain links.
! empty ( $subtermlist ) and FALSE !== strpos( $subtermlist, '<a ' )
and print "<ul class=subterms>$subtermlist</ul>";
}
Use it like wp_list_categories()
.
Avoid get_term_by()
. It is very expensive and not necessary.
