我正在寻找关于如何在特定页面或没有插件的页面上添加特定菜单的帮助。

我知道如何添加和注册这样的新菜单：

//* Register third navigation menu position
function register_additional_menu() {
  register_nav_menu( \'third-menu\' ,__( \'Third Navigation Menu\' ));
}
add_action( \'init\', \'register_additional_menu\' );
add_action( \'genesis_before_content\', \'add_third_nav_genesis\' );

function add_third_nav_genesis() {
    echo\'<div class="osastot-valikko">\';
    wp_nav_menu( array( \'theme_location\' => \'third-menu\', \'container_class\' => \'genesis-nav-menu js-superfish sf-js-enabled sf-arrows\' ) );
    echo\'</div>\';
}

我想有一个名为“额外菜单”的导航菜单只显示在三页上（post=6，post=7，post=8）。我应该在函数中写入什么。php

谢谢

<?php /* Template Name: Page with Menu */ ?>

function add_third_nav_genesis() {
    if( is_page( array( 6, 7, 8 ) ) ) {
        echo\'<div class="osastot-valikko">\';
        wp_nav_menu( array( \'theme_location\' => \'third-menu\', \'container_class\' => \'genesis-nav-menu js-superfish sf-js-enabled sf-arrows\' ) );
        echo\'</div>\';
    }
}
