大家好我是一个新手，上周开始接触CI, 我一贯很懒，学习速度很慢，刚开始学的时候自己做个空项目很难做成东西。所以每次学新的技术下载大量的代码，修改改善原有的项目来学习其中的知识。周一的时候下载STBLOG安装，看了一天代码，觉得Saturn 以及 STBLOG组写的这个程序非常好，非常容易看懂。当发现菜单时用一个插件来生成而不是后台管理的时候就有了自己写一下的冲动  ， 因为插件只生成独立页面的菜单，我相信很多童鞋还想要某个分类或每个分类的菜单。所以动手写了一些这个功能。再声明一下本人是菜鸟，写这个也是为了学习所以希望高手们多多指导。
首先列出新建的文档：
PHP复制代码
APPHOME/controllers/admin/menu.php
APPHOME/views/admin/manage_menu.php
APPHOME/views/admin/menu_cate_form.php
APPHOME/models/menu_mdl.php
首先在数据库中创建一个menu表
SQL复制代码
DROP TABLE IF EXISTS `menu`;
CREATE TABLE `menu` (
`menu_id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '项目主键',
`name` VARCHAR(200) DEFAULT NULL COMMENT '名称',
`url` VARCHAR(50) NOT NULL COMMENT '菜单地址',
`description` VARCHAR(200) DEFAULT NULL COMMENT '选项描述',
`status` tinyint(1) NOT NULL DEFAULT '1' COMMENT '项目状态',
`order` INT(10) UNSIGNED DEFAULT '0' COMMENT '项目排序',
PRIMARY KEY (`menu_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=8 ;
再创建相关的MVC,
一下是新增文档源代码：
PHP复制代码 APPHOME/controllers/admin/menu.php :
PHP复制代码
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Menu extends ST_Auth_Controller {
/**

$this->_data ['type'] = $menu_array['1'];

修改的文档：
PHP复制代码
APPHOME /views /admin /menu .php
APPHOME /controllers /admin /settings .php
APPHOME /views /admin /settings_general .php
数据库中 ->settings 表 增加一个值 menu_status
Themes /default/header.php
现在我们在后台菜单中增加菜单管理菜单项即可
打开 APPHOME/views/admin/menu.php 文档，找到 “管理”， 在合适的地方添加如下代码。
PHP复制代码
<li <?php echo ($currentPage=='manage-menu')? ' class="focus"':'';?>> <?php echo anchor (site_url ('admin/menu/manage/'),'菜单',array('title'=>'菜单'));?></li>
即可在后台管理下出现菜单一项。
现在只剩下一个问题了 如何在首页呈现菜单。
因为已有Saturn 开发的一个插件是生产菜单，所以为了避免与其冲突在后台设置增加了菜单开关。
打开 APPHOME/views/admin/settings_general.php 文档，找到 “站点关闭”的label， 在其之前添加如下代码：(推荐添加到这里，你还可以添加到任何你想要的合适的位置)
HTML复制代码 <label class="typecho-label">
是否关闭菜单 </label>
<span>
<input name="menu_status" id="blog_status_0" type="radio" value="on" <?php echo set_radio('menu_status','on',('on' == $menu_status)?TRUE:FALSE); ?> />
<label for="blog_status_0">
不关闭 </label>
</span>
<span>
<input name="menu_status" type="radio" value="off" id="blog_status_1" <?php echo set_radio('menu_status','off',('off' == $menu_status)?TRUE:FALSE ); ?> />
<label for="blog_status_1">
关闭 </label>
</span>
<p class="description warn" >
关闭菜单时，需要激活菜单插件。菜单插件功能十分简单所以我们推荐您不要关闭菜单。 </p>
</li>
</ul>
多加了一个label到View就得改变其Controller

$setting['blog_slogan'] = $this->input->post('blog_slogan',TRUE);
$setting['blog_description'] = $this->input->post('blog_description',TRUE);
$setting['blog_keywords'] = $this->input->post('blog_keywords',TRUE);
$setting['offline_reason'] = $this->input->post('offline_reason',TRUE);
$setting['upload_dir'] = $this->input->post('upload_dir',TRUE);
$setting['upload_exts'] = $this->input->post('upload_exts',TRUE);
$setting['blog_status'] = $this->input->post('blog_status',TRUE);
$setting['menu_status'] = $this->input->post('menu_status',TRUE);
//Added by Tugh 只增加了这行就可以了
if(empty($setting['upload_dir']))
你在数据库settings表中增加一个记录，name=menu_status.
SQL复制代码
INSERT INTO settings(name)
VALUES ('menu_status')
现在只剩下最后一步工作了 也就是在首页视图中添加菜单生成的语句。
打开 Themes/default/header.php 文件： 找到<div id="menu">
其改成如下
HTML复制代码 <div id="menu">
<ul>
<li><?php echo anchor(site_url(), '首页');?></li>
<?php if(setting_item('menu_status')=='on'): $menus = get_menus(); // 如果菜单功能打开了，就得到菜单并输出?>
<?php if($menus->num_rows() > 0):?>
<?php foreach($menus->result() as $cate):?>
<li><?php echo anchor($cate->url, $cate->name);?> </li>
<?php endforeach;?>
<?php endif;?>
<?php
else: //如果关闭状态则启用菜单插件， 不过记得 插件是激活了才能使用
$this->plugin->trigger('Widget::Navigation', ' <li><a href="{permalink}">{title} </a></li>');
?>
<?php endif;?>
</ul>
</div>
代码都贴出来有点长了 不知道会不会有人看。 最后贴几张效果图：
