您可以从wordpress菜单面板中输入自定义链接。

你可以用钩子做你的主题wp_nav_menu_items :

add_filter(\'wp_nav_menu_items\', \'wpse_104145_custom_home_link\', 10, 2);
function wpse_104145_custom_home_link($items, $args) {

if( $args->theme_location == \'primary\' )
    global $post;
    if($post->post_parent) {
    $permalink = get_permalink($post->post_parent);
    $homeLink = \'<li id="home_link"><a href="\' . $permalink . \'">\'.get_the_title($post->post_parent).\'</a></li>\';
    return $homeLink . $items;
    } else {
    return $items;
    }
}
