How to get term id of custom taxonomy

  • I have made a custom taxonomy called ‘item’, and make a list of terms of it with code:

    $args_list = array(
	'taxonomy' => 'item', // Registered tax name
	'show_count' => true,
	'hierarchical' => true,
'hide_empty' => '0',
'title_li' => '',
	'echo' => '0',
);
echo wp_list_categories($args_list);

    Taxonomy terms are like:
    Country
    – USA
    – Canda
    Planet
    – earth
    – mars

    Now, I trying to get list of child terms of current term in another place of template, but can’t get current term ID. How can I get it? Thanx

    thanx very much, your code working fine, but one problem for me.

    This code returns an unordered list of all child terms, but my structure has many levels, and I want now to display only one child level of current page, something like ‘depth=1’ in wp_list_categories.

    How may i modify this code? Woul be very pleasant for u!

    Try it with this:

    $term_slug = get_query_var( 'term' );
  $taxonomyName = get_query_var( 'taxonomy' );
  $current_term = get_term_by( 'slug', $term_slug, $taxonomyName );
  $termchildren = get_term_children( $current_term->term_id, $taxonomyName);
  if($termchildren && ( !is_wp_error( $termchildren ))){
    echo '<ul>';
    foreach ($termchildren as $child) {
      $term = get_term_by( 'id', $child, $taxonomyName );
      if($current_term->term_id == $term->parent){
        echo '<li><a href="' . get_term_link( $term->name, $taxonomyName ) . '">' . $term->name . '</a></li>';
      }
    }
    echo '</ul>';
  }

    Or this ??

    $term_slug = get_query_var( 'term' );
$taxonomyName = get_query_var( 'taxonomy' );
$current_term = get_term_by( 'slug', $term_slug, $taxonomyName );
$args_list = array(
    'taxonomy' => 'item', // or use $taxonomyName for all taxonomies
    'show_count' => true,
    'hierarchical' => true,
    'child_of' => $current_term->term_id,
    'hide_empty' => '0',
    'title_li' => '',
    'echo' => '0',
);
echo wp_list_categories($args_list);

    to avoid the message No categories if there is no child categories, you can use after 3rd string ($current_term…) keesiemeijer’s condition code ??

    $termchildren = get_term_children( $current_term->term_id, $taxonomyName);
if($termchildren && ( !is_wp_error( $termchildren ))) {
 // whole section with $args_list and wp_list_categories($args_list) here;
}
