Sure, here’s a direct idea that you can use to display the taxonomy hierarchy on your WordPress website:

You can use the get_ancestors() function in WordPress to retrieve the ancestors of a taxonomy term. This function returns an array of term IDs, which you can then use to display the hierarchy.

Here’s an example code snippet that you can use:

<?php
// Get the current taxonomy term
$term = get_queried_object();

// Get the ancestors of the current term
$ancestors = get_ancestors( $term->term_id, $term->taxonomy );

// If there are ancestors, display them
if ( $ancestors ) {
// Reverse the order of ancestors to display them from parent to child
$ancestors = array_reverse( $ancestors );

// Loop through the ancestors and display them
for each ( $ancestors as $ancestor ) {
$ancestor_term = get_term( $ancestor, $term->taxonomy );
echo esc_html( $ancestor_term->name ) . ‘ – ‘;
}
}

// Display the current term
echo esc_html( $term->name );
?>
This code will retrieve the ancestors of the current taxonomy term and display them with the current term, separated by a dash. You can modify the output as per your requirements.
