moodle2.4 DIY 导航block的实例

//这里我改成 这样 后面有一个配置文件 读取 导航菜单的数据
//moodle/lib/navigationlib.php 1261行 或者搜索 "// Remove any empty root nodes"
foreach ($this->rootnodes as $node) {
            // Dont remove the home node
            if ( $node->key !== 'courses' &&!in_array( $node->key , array(1,2,3,4,5,6,7,8,9)) ) {
                $node->remove();
            }
        }
//moodle/lib/navigationlib.php 1068行 或者搜索 "$this->rootnodes['users'] = $this->add(get_string('users'), null, self::TYPE_ROOTNODE, null, 'users');"

// @添加几行代码
        chmod( $CFG->dirroot . '/navigation.config.php' , 0777);
        $navigation_data = require( $CFG->dirroot . '/navigation.config.php');

        foreach ( $navigation_data as $key => $value) {
            $this->rootnodes[$key] = $this->add( $value['text'] , null , self::TYPE_ROOTNODE , null , $key);
            
            foreach( $value['branch'] as $url){
                $this->rootnodes[$key]->add_node( navigation_node::create( $url['text'], new moodle_url( $url['url']), self::NODETYPE_BRANCH, null, null, new pix_icon( $url['icon'] , '') ));
            }
        }



//现在写个根目录下的配置文件 navigation.config.php
<?php
return array(
	1 => array(
		'text' => '学习中心',
		'branch' => array(
				0	=> array(
					'text'	=> '我的课程',
					'url' 	=> '/course/',
					'icon' 	=> 'i/db',
					),
				1 	=> array(
					'text'	=> '成绩',
					'url'	=> '/grades/',
					'icon'	=> 'i/manual_item',
					),
				2 	=> array(
					'text'	=>'问答',
					'url'	=>'/quest/',
					'icon'	=>'i/feedback',
					),

		),
	),

	2 => array(
		'text' => '账户管理',
		'branch' => array(
				0	=> array(
					'text'	=>'账户',
					'url'	=>'/user/',
					'icon'	=>'i/lock',
				),

				1	=> array(
					'text'	=>'订单',
					'url'	=>'/order/',
					'icon'	=>'i/payment',
				),
		),
	),
);
再刷新 moodle页面，导航就被修改成自己需要的样子了。因为moodle不带自定义功能，所以只能这样修改
