试着从页面管理链接中只取一个名称，看看它是否有效。类似这样：

function custom_menu_order($menu_ord) {
    if (!$menu_ord) return true;

    return array(
        \'index.php\', // Dashboard
        \'separator1\', // First separator
        \'edit.php\', // Posts

        \'pluginname2\', // Take the name from the page menu admin.php?page=pluginname2

        \'upload.php\', // Media
        \'edit.php?post_type=page\', // Pages
        \'edit-comments.php\', // Comments

        \'pluginname\', // Take the name from the page menu admin.php?page=pluginname

    );
}
add_filter(\'custom_menu_order\', \'custom_menu_order\'); // Activate custom_menu_order
add_filter(\'menu_order\', \'custom_menu_order\');
