List in sidebar Wordpress Taxonomy list

Question

I have the following structure:

Custom Taxonomy Car Brands

• Ford
  • Car x
  • Carro Y
  • Car Z
• Audi

I want to list on sidebar all cars from ford registered. How can I do without plugin?

Answer 1

Use the function get_term_by() to retrieve Ford’s ID and wp_list_categories() to list child terms. If taxonomy is not category change in the example by the appropriate name:

<ul>
<?php 
    $parent = get_term_by( 'name', 'Ford', 'category' );
    wp_list_categories( array(
        'childof' => $parent->term_id,
        'taxonomy' => 'category',
    ) );
?> 
</ul>
