1. 新建存储菜单的配置文件 menus.php,并配置菜单

   <?php  if ( ! defined(‘BASEPATH‘)) exit(‘No direct script access allowed‘);/*菜单配置*/$config[‘menus‘] = array();// 校园生活$config[‘menus‘][‘life‘] = array(‘name‘ => ‘学校生活‘,     ‘submenu‘ => array(        ‘news/official_news‘ => array(‘name‘ => ‘官网公告‘),        ‘life/game‘ => array(‘name‘ => ‘校园活动‘, ‘link‘ => ‘life/game‘),        ‘life/flea‘ => array(‘name‘ => ‘跳蚤专场‘, ‘link‘ => ‘life/flea‘),        ‘life/calendar‘ => array(‘name‘ => ‘跳蚤专场‘, ‘link‘ => ‘life/calendar‘),        ‘life/map‘ => array(‘name‘ => ‘校园地图‘, ‘link‘ => ‘life/map‘),        ‘life/scenery‘ => array(‘name‘ => ‘校园美景‘, ‘link‘ => ‘life/scenery‘),        ‘life/schoolcard_lose‘ => array(‘name‘ => ‘一卡通丢失‘, ‘link‘ => ‘life/schoolcard_lose‘),        ‘life/schoolcard_found‘ => array(‘name‘ => ‘一卡通招领‘, ‘link‘ => ‘life/schoolcard_found‘),    ));// 校园学习$config[‘menus‘][‘study‘] = array(‘name‘ => ‘学校生活‘,     ‘submenu‘ => array(        ‘study/translate‘ => array(‘name‘ => ‘翻译一下‘, ‘link‘ => ‘study/translate‘),        ‘study/source‘ => array(‘name‘ => ‘分享资源‘, ‘link‘ => ‘study/source‘),        ‘study/method‘ => array(‘name‘ => ‘小谈学习‘, ‘link‘ => ‘study/method‘),        ‘study/cet‘ => array(‘name‘ => ‘查询四六级成绩‘, ‘link‘ => ‘study/cet‘),    ));// 校园名片$config[‘menus‘][‘card‘] = array(‘name‘ => ‘校园名片‘, ‘link‘ => ‘card/index‘);

2. 新建菜单类，Menu.php，并创建获取菜单配置数据的方法（貌似有点多余）/优化方法，修改为读取配置类，封装获取配置文件

   <?php if ( ! defined(‘BASEPATH‘)) exit(‘No direct script access allowed‘); class Menu{    /**     * 获取菜单配置     */    public function get_menus($param) {        $CI =& get_instance();        $CI->config->load(‘menus‘);        $menus = $CI->config->item(‘menus‘);        return $menus;    }}

3. 控制器index.php 调用菜单类，获取菜单配置数据，赋值模板

   /**     * 首页     */    function index() {        //引入menu类，获取菜单配置        $this->load->library(‘menu‘);        $data[‘menus‘] = $this->menu->get_menus();        $this->load->view(‘index.html‘, $data);    }

4. 模板循环输出菜单

   <ul class="nav navbar-nav navbar-left">                    <li class="active">                        <a href=http://www.mamicode.com/"/"> class="glyphicon glyphicon-home"></i>                        </a>                    </li>                    <?php foreach ($menus as $menu): ?>                        <?php if ( ! isset($menu[‘submenu‘]) ): ?>                            <li>                                <a href=http://www.mamicode.com/"<?=site_url($menu[‘link‘])?>"><?=$menu[‘name‘]?></a>                            </li>                        <?php else: ?>                            <li>                                <a href=http://www.mamicode.com/"" class="dropdown-toggle" data-toggle="dropdown" aria-expanded="false">                                    <?=$menu[‘name‘]?>                                    <span class="caret"></span>                                </a>                                <ul class="dropdown-menu" role="menu">                                    <?php foreach ($menu[‘submenu‘] as $link => $submenu): ?>                                    <li>                                        <a href=http://www.mamicode.com/"<?=site_url($submenu[‘link‘])?>"><?=$submenu[‘name‘]?></a>                                    </li>                                                                    <?php endforeach ?>                                </ul>                            </li>                                                    <?php endif ?>                    <?php endforeach ?>                </ul>

主页菜单部分没完成，困了。明天再配置
