桂电在线-php-提取菜单到配置文件

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