您可以检查用户ID：

// admin_init action works better than admin_menu in modern wordpress (at least v5+)
add_action( 'admin_init', 'my_remove_menu_pages' );
function my_remove_menu_pages() {

  global $user_ID;

  if ( $user_ID != 1 ) { //your user id

   remove_menu_page('edit.php'); // Posts
   remove_menu_page('upload.php'); // Media
   remove_menu_page('link-manager.php'); // Links
   remove_menu_page('edit-comments.php'); // Comments
   remove_menu_page('edit.php?post_type=page'); // Pages
   remove_menu_page('plugins.php'); // Plugins
   remove_menu_page('themes.php'); // Appearance
   remove_menu_page('users.php'); // Users
   remove_menu_page('tools.php'); // Tools
   remove_menu_page('options-general.php'); // Settings
  }
}

您可以使用以下命令删除给定电子邮件的帖子菜单：

function custom_menu_page_removing() {
    if ( get_currentuserinfo()->user_email != 'shaun@seedcreativity.co.uk' )
        remove_menu_page( 'edit.php' );
}
add_action( 'admin_menu', 'custom_menu_page_removing' );

如果用户能猜到正确的URL，例如/wp-admin/edit.php，它不会阻止用户使用已删除的页面

你可以试试这个代码。

function remove_menus(){
     $current_user = wp_get_current_user();
    if( 'shaun@seedcreativity.co.uk' !==  $current_user->user_email){
        remove_menu_page( 'item1' ); 
        remove_menu_page( 'item2' ); 
    }

}
add_action( 'admin_menu', 'remove_menus' );

item1、item2是您的页面名称，例如http://test.com/wp-admin/admin.php?page=item1http://test.com/wp-admin/admin.php?page=item2

要隐藏woocommerce，营销，acf字段和分析菜单使用下面的代码

add_action( 'admin_init', 'remove_menu_pages' );
function remove_menu_pages() {

  global $user_ID;

  if ( $user_ID != 1 ) { 
   remove_menu_page( 'edit.php?post_type=acf-field-group' );
   remove_menu_page( 'edit.php?post_type=product' );
   remove_menu_page('woocommerce');
   remove_menu_page('wc-admin&path=/analytics/overview');
   remove_menu_page('woocommerce-marketing');
  }
}
