You can use get_ancestors
:
<?php
if ( $term_ids = get_ancestors( get_queried_object_id(), \'category\', \'taxonomy\' ) ) {
$crumbs = [];
foreach ( $term_ids as $term_id ) {
$term = get_term( $term_id, \'category\' );
if ( $term && ! is_wp_error( $term ) ) {
$crumbs[] = sprintf( \'<a href="%s">%s</a>\', esc_url( get_term_link( $term ) ), esc_html( $term->name ) );
}
}
echo implode( \' > \', array_reverse( $crumbs ) );
}
