有人能帮我们举一个如何在Kohana 3.2.2 中使用外部文件（css、Javascript和图像）的例子吗
以下是我所做的：在/classes/controller/hello.php中
<?php defined('SYSPATH') OR die('No Direct Script Access');
Class Controller_Hello extends Controller_Template
{
public $template = 'site'; // Default template
public function action_index()
{
$this->template->styles = array('media/css/style.css'=>'screen');
//$this->template->scripts = array('assets/js/jqtest.js');
}
public function before()
{
parent::before();
if($this->auto_render)
{
// Initialize empty values
$this->template->styles = array();
$this->template->scripts = array();
}
}
/**
* Fill in default values for our properties before rendering the output.
*/
public function after()
{
if($this->auto_render)
{
// Define defaults
$styles = array('media/css/style.css' => 'screen');
//$scripts = array(‘http://ajax.googleapis.com/ajax/libs/jquery/1.3.2.js');
// Add defaults to template variables.
$this->template->styles=array_reverse(array_merge
($this->template->styles,$styles));
//$this->template->scripts =array_reverse(array_merge
($this->template->scripts, $scripts));
}
// Run anything that needs to run after this.
parent::after();
}
}
然后在你看来，你只需要使用这个/application/views/site.php
<head>
<?php
foreach($styles as $file => $type)
{
echo HTML::style($file, array('media' => $type)), "";
}
?>
</head>
将图像添加到视图
<li class="social"><?php echo html::image('media/images/phone.png');?>
取决于是否要通过控制器运行它们。如果您想使用HMVC加载媒体文件，请使用示例控制器。
/classes/controller/media.php
class Controller_Media extends Controller {
protected $config = NULL;
public function before()
{
parent::before();
$this->config = Kohana::$config->load('media');
}
public function action_css()
{
$this->handle_request(
'style',
$this->request->param('path'),
$this->config['styles']['extension']
);
}
public function action_js()
{
$this->handle_request(
'script',
$this->request->param('path'),
$this->config['scripts']['extension']
);
}
public function action_img()
{
$image = $this->config['images']['directory'].$this->request->param('path');
$extension = $this->find_image_extension($image);
$this->handle_request(
'image',
$this->request->param('path'),
$extension
);
}
protected function handle_request($action, $path, $extension)
{
$config_key = Inflector::plural($action);
$file = $this->config[$config_key]['directory'].$path;
if ($this->find_file($file, $extension))
{
$this->serve_file($file, $extension);
}
else
{
$this->error();
}
}
protected function find_file($file, $extension)
{
$path_parts = pathinfo($file);
return Kohana::find_file('media', $path_parts['dirname']."/".$path_parts['filename'], $extension);
}
protected function find_image_extension($file)
{
foreach ($this->config['images']['extension'] as $extension)
{
if ($this->find_file($file, $extension) !== FALSE)
{
return $extension;
}
}
return FALSE;
}
protected function serve_file($file, $extension)
{
$path = $this->find_file($file, $extension);
$this->response->headers('Content-Type', File::mime_by_ext($extension));
$this->response->headers('Content-Length', (string) filesize($path));
$this->response->headers('Cache-Control','max-age=86400, public');
$this->response->headers('Expires', gmdate('D, d M Y H:i:s 'G'M'T', time() + 86400));
$this->response->body(file_get_contents($path));
}
protected function error()
{
throw new HTTP_Exception_404('File :file not found.', array(
':file' => $this->request->param('path', NULL),
));
}
}
/config/media.php
return array(
'styles' => array(
'directory' => 'css/',
'extension' => 'css',
),
'scripts' => array(
'directory' => 'js/',
'extension' => 'js',
),
'images' => array(
'directory' => 'img/',
'extension' => array('png', 'jpg', 'jpeg', 'gif', 'ico', 'svg'),
),
);
routes.php
Route::set('media', 'media/<action>(/<path>)', array(
'path' => '.*?',
))
->defaults(array(
'controller' => 'media',
'action' => 'index',
));
默认.htaccess应该处理根目录中的任何内容，而不需要任何额外的代码。
/webroot
--> application/
--> modules/
--> system
--> css/
--> scripts/
来自的任何呼叫http://domain.com/css将正确地在css/中查找，因为.htaccess规则首先查找现有文件/文件夹，然后从Kohana加载index.php。
