我从一个类似的问题中总结出了这一点。如果其他人需要：

<?php
$terms = get_terms( array(
    \'taxonomy\' => \'features\',
    \'hide_empty\' => false
    ) );

    if (!empty($terms) && ! is_wp_error( $terms )) {
        echo \'<section>\';
        foreach ($terms as $term) {
            $class = has_term( $term->term_id, \'features\' ) ? \'active\' : \'unassigned\';
            echo \'<div class="term \' . $class . \'"><h6>\' . $term->name . \'</h6>\';
            echo \'<div class="availability"></div>\';
            echo \'<p>\'.$term->description.\'</p></div>\';
        }  
        echo \'</section>\';  
} ?>
