Asset Manager

Usage

Basic usage would be to include assets throughout your application, in controllers most likely. Perhaps you have a base controller that the rest of your controllers extend where you include your base or default CSS and Javascript files. Then in other controllers you can add or remove assets according to what is needed for the respective action.

/application/controllers/base.php

abstract class Controller_Base extends Controller_Template {

	public function before()
	{
		// Call parent
		parent::before()

		// Setup default styles, javascript, and groups
		Assets::css('global', 'assets/css/global.css', array('grid', 'reset'), array('media' => 'screen'));
		Assets::css('reset', 'assets/css/reset.css');
		Assets::css('grid', 'assets/css/grid.css', 'reset');
		
		Assets::js('jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js');
		Assets::js('global', 'assets/js/global.js', array('jquery'));
		Assets::js('stats', 'assets/js/stats.js', NULL, TRUE);
		
		Assets::group('head', 'keywords', '<meta name="keywords" content="'.$this->keywords.'" />');
		Assets::group('head', 'description', '<meta name="description" content="'.$this->description.'" />');
	}

}

/application/controllers/blog.php

class Controller_Blog extends Controller_Base {

	public function before()
	{
		// Call parent
		parent::before()

		// We don't need 'stats.js' within Blog Controller, so don't load it.
		Assets::remove_js('stats');
	}
	
	public function action_index()
	{
		// Add CSS for the blog index
		Assets::css('blog', 'assets/css/blog.css', array('global'));
		
		// We don't need 'global.js' on this page, so don't load it.
		Assets::remove_js('global');
	}
	
}

Then you would output the assets in your template somewhere

/application/views/template.php

<html>
	<head>
		<title>Kohana Assets</title>
		<?php echo Assets::group('head') ?>
		<?php echo Assets::css() ?>
		<?php echo Assets::js() ?>
	</head>
	<body>
		<!-- Content -->
		<?php echo Assets::js(TRUE) ?>
		<?php echo Assets::group('footer') ?>
	</body>
</html>

You could even include the CSS and Javascript into a group if you want

Assets::group('head', 'css', Assets::css());
Assets::group('head', 'js', Assets::js());

Dependencies

To provide maximum flexibility over assets you don't necessarily have direct control over, you can define assets that other assets depend on to function correctly. For instance, jQuery UI is dependant on jQuery to work. If jQuery is included somewhere else in your application, you wouldn't want to include jQuery UI and have it show up before jQuery in the source. So by providing dependencies, we can make sure that never happens.

Assets::js('jquery-ui', 'https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.10/jquery-ui.min.js', array('jquery'));

Other Functions

Getting a single asset

$global = Assets::js('global');
// returns <script src="/assets/js/global.js"></script>

echo Assets::group('head', 'keywords');

Removing assets

Assets::remove_css('grid');

// Remove all CSS
Assets::remove_css();

Assets::remove_group('head');
