PHP HMVC框架kohana 小结1
之前kohana 3的安装见:http://jackyrong.iteye.com/admin/blogs/1186006
1 在bootstrap中设置开发模式:
Kohana::$environment = Kohana::DEVELOPMENT;
再增加如下代码:
if (isset($_SERVER['KOHANA_ENV']))
{
Kohana::$environment = $_SERVER[?KOHANA_ENV?];
}
相关的值有:
PRODUCTION, STAGING, TESTING, and DEVELOPMENT.
2 设置时区
date_default_timezone_set('America/Chicago');
3 启用相关的module
Kohana::modules(array( 中的注释按需要打开
4 创建默认的config文件(这点比CI差了)
在application\config下设置一个比如site.php的文件,放置日常用的变量,比如:
return array(
'name' => 'Egotist',
'tag_line' => "Let's talk about me!"
);
则获得其变量时,这样:
$site_config = Kohana::config('site');
$site_name = $site_config['name'];
$tag_line = $site_config['tag_line'];
甚至可以这样只加载其中的某个变量:
$site_name = Kohana::config('site.name');
也可以数组的形式加载变量,比如:
return array(
'name' => 'Egotist',
'details' => array(
'tag_line' => "Let's talk about me!",
'alt_tag_line' => "Today's subject: ME!";
);
);
加载:
$site_config = Kohana::config('site');
// Echo site name and details
echo $site_config['name']; // Egotist
echo $site_config['details']['tag_line'] // Lets talk about me!
echo $site_config['details']['alt_tag_line'] // Today's subject: ME!
也可以:
echo Kohana::config('site.details.tag_line');
5 controller的命名规范,必须符合如下
Controller_xxxx,XXX放在classes/controller/xxx.php,比如
Controller_User_Profile则为 classes/controller/user/profile.php
6 给view传递数据
controller中:
public function action_index()
{
//3.2只能用这个方法
$view = View::factory('welcome')
->set('site_name', 'Egotist')
->set('random', rand(1,10));
$this->response->body($view);
}
view中:
