|

*
|
|
* Include one CSS file:

* `echo $this->Html->css('styles.css');`

*

* Include multiple CSS files:

*

* Add the stylesheet to the `$scripts_for_layout` layout var:

*

* - `plugin` False value will prevent parsing path as a plugin
|

* - `fullBase` If true the url will get a full address for the css file.
|
|
*
|
|
* @param string|array $path The name of a CSS style sheet or an array containing names of
|
|
* CSS stylesheets. If `$path` is prefixed with '/', the path will be relative to the webroot
|
|
* of your application. Otherwise, the path will be relative to your CSS path, usually webroot/css.
|
|
* @param string $rel Rel attribute. Defaults to "stylesheet". If equal to 'import' the stylesheet will be imported.
|
|
* @param array $options Array of HTML attributes.
|
|
* @return string CSS <link /> or <style /> tag, depending on the type of link.

|
* If the filename is prefixed with "/", the path will be relative to the base path of your
|
|
* application. Otherwise, the path will be relative to your JavaScript path, usually webroot/js.
|
|
*
|
|
*
|
|
* ### Usage
|
|
*
|
|
* Include one script file:
|
|
*
|
|
* `echo $this->Html->script('styles.js');`
|
|
*
|
|
* Include multiple script files:
|
|
*
|
|
* `echo $this->Html->script(array('one.js', 'two.js'));`
|
|
*
|
|
* Add the script file to the `$scripts_for_layout` layout var:
|
|
*
|
|
* `$this->Html->script('styles.js', array('inline' => false));`
|
|
*
|
|
* Add the script file to a custom block:
|
|
*
|
|
* `$this->Html->script('styles.js', null, array('block' => 'bodyScript'));`
|
|
*
|
|
* ### Options
|
|
*
|
|
* - `inline` Whether script should be output inline or into `$scripts_for_layout`. When set to false,
|
|
* the script tag will be appended to the 'script' view block as well as `$scripts_for_layout`.
|
|
* - `block` The name of the block you want the script appended to. Leave undefined to output inline.
|
|
* Using this option will override the inline option.
|
|
* - `once` Whether or not the script should be checked for uniqueness. If true scripts will only be
|
|
* included once, use false to allow the same script to be included more than once per request.
|
|
* - `plugin` False value will prevent parsing path as a plugin
|
|
* - `fullBase` If true the url will get a full address for the script file.
|
|
*
|
|
* @param string|array $url String or array of javascript files to include
|
|
* @param array|boolean $options Array of options, and html attributes see above. If boolean sets $options['inline'] = value
|
|
* @return mixed String of `<script />` tags or null if $inline is false or if $once is true and the file has been
|
|
* included before.

|
|

*
|
|
* Using a video file:
|
|
*
|
|
* `echo $this->Html->media('video.mp4', array('text' => 'Fallback text'));`
|
|
*
|
|
* Outputs:
|
|
*
|

* ### Options
|

* If tag is not provided it's guessed based on file's mime type.
|
|
* - `text` Text to include inside the audio/video tag
|
|
* - `pathPrefix` Path prefix to use for relative urls, defaults to 'files/'
|
|
* - `fullBase` If provided the src attribute will get a full address including domain name
|
|
*
|
|
* @param string|array $path Path to the video file, relative to the webroot/{$options['pathPrefix']} directory.
