Show parent taxonomy in custom post type

Solution

I didn't test the following script, but I hope it will bring you a step forward to the solution.

// begin loop
$args = array('post_type' => 'school');
query_posts($args); if ( have_posts() ) : while ( have_posts() ) : the_post();

// variable for location
$term_list = '';
$terms     = get_the_terms( $post->ID, 'location' );
$prefix    = '';

foreach( $terms as $term ) {
    $parent_term = get_term( $term->parent, 'location' );
    $term_list  .= $prefix . $parent_term->name . ' - ' . $term->name;
    $prefix      = ', ';
}

// output
echo get_the_title() . ' - ' . $term_list;

// end loop
endwhile; endif;

Problem

I have a set of schools in a custom post type with locations ordered as follows: ``` London - 1 Oxford Road - 2 Cambridge Road Paris - 1 Napoleon Road - 2 Tower Road ``` How do I change the following so that the location parent is outputted instead of the location child: ``` // begin loop $args = array('post_type' => 'school'); query_posts($args); if ( have_posts() ) : while ( have_posts() ) : the_post(); // variable for location $location = get_the_term_list( $post->ID, 'location', '', ', ', '' ); // output echo get_the_title() . ' - ' . $location; // end loop endwhile; endif; ``` Thank you.
