注册菜单有两个功能：1。register\\u nav\\u菜单2。register\\u nav\\u菜单。第一个只注册一个菜单位置，另一个接受菜单数组。因此，如果要添加新的菜单位置，则需要使用register\\u nav\\u menus（）；

    register_nav_menus( array(
                    \'your_current_menu_location\' => __( \'Your current menu label\', \'your_theme\' ),
                    \'additional_location_\' => __( \'Your additional menu label\', \'your_theme\'),

        //etc...
                ) );

您需要将其添加到函数中。php文件，并删除现有的nav\\u菜单功能：

<?php
add_action( \'init\', \'register_my_menus\' );
function register_my_menus() {
register_nav_menus(
  array(
    // Add Your Current Menu Register Here And Replace The Current Code With This
    \'secondary\' => \'secondary\' ,
    \'tertiary\' =>  \'tertiary\',
    )
  );
}
?>

To use the menu\'s you would place this in the template desired:

<?php wp_nav_menu( array( \'theme_location\' => \'secondary\' ) ); ?>

OR:

<?php wp_nav_menu( array( \'theme_location\' => \'tertiary\' ) ); ?>
