Phalcon - Asset Management

Assets are all about the additional components apart from the existing framework in Phalcon. Phalcon has an asset manager which helps to manage all the asset components like CSS or JS files.
The common methods used are −

Method	Importance
__construct(variable $options)	Initializes the component Phalcon\Assets\Manager
addCss(string $path, variable $local, variable $filter, variable $attributes)	Adds a CSS resource from the 'css' collection to a particular view
addJs(string $path, variable $local, variable $filter, variable $attributes)	Adds a JavaScript resource to the 'js' collection

Example

Consider the sample project of Phalcon “vokuro” which is the best illustration for adding css files. It will include assets/Manager for invoking all the css files.
The default controller for the project will invoke all the css files.

<?php 

namespace Vokuro\Controllers; 
use Phalcon\Assets\Manager;  

/** 
   * Display the default index page. 
*/ 

class IndexController extends ControllerBase {  
   /** 
      * Default action. Set the public layout (layouts/public.volt) 
   */ 
   public function indexAction() { 
      $this->assets->addCss("public/style.css"); 
      $this->view->setVar('logged_in', is_array($this->auth->getIdentity())); 
      $this->view->setTemplateBefore('public'); 
   } 
}

Style.css

div.remember { 
   margin-top: 7px; 
   color: #969696; 
}  
div.remember label { 
   padding-top: 15px; 
}  
div.forgot { 
   margin-top: 7px; 
   color: #dadada; 
}  
footer { 
   background: url("../img/feature-gradient.png") no-repeat scroll center 100% white; 
   color: #B7B7B7; 
   font-size: 12px; 
   padding: 30px 0; 
   text-align: center; 
}  
footer a { 
   margin-left: 10px; 
   margin-right: 10px; 
}  
table.signup td { 
   padding: 10px; 
}  
table.signup .alert { 
   margin-bottom: 0; 
   margin-top: 3px; 
}  
table.perms select { 
   margin-top: 5px; 
   margin-right: 10px; 
}  
table.perms label { 
   margin-right: 10px; 
}  
div.main-container { 
   min-height: 450px; 
} 

The assets will be managed inside views, which will display css files as an output.

Index.volt

{{ content() }} 
{{ assets.outputCss() }} 

<header class = "jumbotron subhead" id = "overview"> 
   <div class = "hero-unit"> 
      <h1>Welcome!</h1> 
      <p class = "lead">This is a website secured by Phalcon Framework</p> 
      <div align = "right"> 
         {{ link_to('session/signup', '<i class="icon-ok icon-white">
            </i> Create an Account', 'class': 'btn btn-primary btn-large') }} 
      </div> 
   </div> 
</header>
