PHP HMVC框架kohana 小结1

heshao2005

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：
  <?php defined('SYSPATH') or die('No direct script access.');
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：
  <h1>Welcome to <?php echo $site_name; ?></h1>
<?php echo $random; ?> is a number between 1 and 10


  也可以用bind绑定
   
$view = View::factory('welcome')->bind('site_name', $site_name)
->bind('random', $random);
$site_name = 'Egotist';
$random = rand(1, 10);

$this->response->body($view);

7 使用template controller
    class Controller_Welcome extends Controller_Template
  {
     $content = View::factory('welcome')
->bind('random', $random);
$random = rand(1, 10);
$content->site_name = 'Egotist Beta';
$this->template->content = $content;
}
    }
   
   页面中直接输出：
    <?php echo $content;?>

8 设置全局变量，以方便在各页面中直接读取
      View::set_global('site_name', 'Egotist Beta');
   之后可以在任何view中读取：
        <?php echo $site_name; ?>
9 在控制层中，写一个基类，保存一些基本的信息，比如CSS，JAVASCRIPT，常量可以这

样：
    abstract class Controller_Application extends Controller_Template {
public function before()
{
parent::before();
View::set_global('site_name', 'Egotist Beta');
$this->template->content = '';
$this->template->styles = array();
$this->template->scripts = array();
}
   
   其他PHP控制层文件再继承之，十分好用
