列出您可以使用的名称和描述get_terms(). 这将返回一个包含所有项的数组。例如：

global $post;    
$terms = get_terms( array(
    \'taxonomy\' => \'item_tags\',
    \'hide_empty\' => false,
) );
if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
    foreach ( $terms as $term ) {
        echo \'<h2>\' . $term->name . \'</h2>\';
        echo apply_filters( \'the_content\', $term->description );
        $items = get_posts( array (
            \'post_type\' => \'item\',
            \'tax_query\' => array(
                array(
                    \'taxonomy\' => \'item_tags\',
                    \'terms\'    => $term->term_id,
                ),
            ),
        ) );
        foreach ( $items as $post ) {
            setup_postdata( $post );
            ?>
            <div>
                <h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
                <?php the_excerpt(); ?>
            </div>
            <?php
        }
    }
    wp_reset_postdata();
}
