如果我理解正确，您希望显示父类别本身，而不是其帖子，对吗？get_terms 是你需要的。

$top_level_categories = get_terms( \'category\', array(
    \'parent\' => 0, // This will get ONLY top level items
    \'hide_empty\' => false // This will make sure even empty categories are returned
) );
print_r( $top_level_categories );

类别列表（不包括任何子类别）可以通过以下代码显示。不要害怕大量的论点，它们不是强制性的。

         <?php $args = array(
            \'show_option_all\'    => \'\',
            \'show_option_none\'   => \'\',
            \'orderby\'            => \'ID\', 
            \'order\'              => \'ASC\',
            \'show_count\'         => 0,
            \'hide_empty\'         => 0, 
            \'child_of\'           => 0,
            \'exclude\'            => \'0\',
            \'echo\'               => 1,
            \'selected\'           => 0,
            \'hierarchical\'       => 1, 
            \'name\'               => \'category\',
            \'id\'                 => \'\',
            \'class\'              => \'postform\',
            \'depth\'              => 1,
            \'tab_index\'          => 0,
            \'taxonomy\'           => \'category\',
            \'title_li\' => __( \'\' ),
            \'hide_if_empty\'      => false
        ); ?>

        <ul class="top-level">
            <?php wp_list_categories( $args ); ?>
        </ul>

法典：wp_list_categories().
