Available Helpers

HeadIcons

This helper just extends the standard HeadLink view helper with some useful shorcuts and amends the acceptable attributes to include the 'sizes' attribute for Apple touch icons.

Example in a layout View

	$this->headIcons()->setWindowsIcon($this->basePath('favicon.ico'));
	$this->headIcons()->setShortcutIcon($this->basePath('favicon.png'));
	$this->headIcons()->addAppleTouchIcon($this->basePath('apple-touch-icon-144x144.png'), 144, 'image/png', true);
	$this->headIcons()->addAppleTouchIcon($this->basePath('apple-touch-icon-114x114.png'), 114, 'image/png', true);
	$this->headIcons()->addAppleTouchIcon($this->basePath('apple-touch-icon-72x72.png'), 72, 'image/png', true);
	$this->headIcons()->addAppleTouchIcon($this->basePath('apple-touch-icon.png'), NULL, 'image/png', true);
	echo $this->headIcons()->setSeparator("\n\t");

HeadOg

This helper extends Zend\View\Helper\HeadMeta and overrides isValid() so that we can output meta properties for pages with an HTML5 doctype. There's a bunch of methods that are helpful in views. It's a bit ugly and doesn't do video and many other useful things but it'll get there...

$this->headOg()->setOgTitle('Set a specific OG Title');
$this->headOg()->setOgDescription('And a specific description');

Easier manipulation of the Facebook Admins Property:

$this->headOg()->setFacebookAdmins(array('ID1', 'ID2'));
$this->headOg()->addFacebookAdmin('ID3');
// would render <meta property="fb:admins" content="ID1,ID2,ID3">

Convenience setters/getters for og:type and og:site_name

$this->headOg()->setOgType('website');
$this->headOg()->setOgSiteName('Foo');
var_dump($this->headOg()->getOgType()); // 'website'

Add multiple images easily:

// String url required at a bare minimum
$this->headOg()->addImage('http://example.com/image1.png');

// Specify any other valid image property
$this->headOg()->addImage(array(
	'url' => 'http://example.com/image2.png',
	'type' => 'image/png',
	'width' => 100,
	'height' => 100,
	'secure_url' => 'https://example.com/image2.png',
));

Applies the head title and meta description to corresponding og:title and og:description automatically by default to reduce FB Lint errors/warnings

Is constructed by the service manager so you can set options for all pages and selectively add or alter within views only the important stuff

return array(
	'open_graph' => array(
		// Setup any scalar property you like
		'headProperties' => array(
			'fb:page_id' => 'some id',
			'og:site_name' => 'Foo',
			'twitter:card' => 'summary',
			// etc...
		),
		// Arrays of image specs, though as a full uri is required - you would probably add the images from your layout/view
		'images' => array(
			array(
				'url' => 'http://example.com/image2.png',
				'type' => 'image/png',
				'width' => 100,
				'height' => 100,
				'secure_url' => 'https://example.com/image2.png',
			),
		),
		
		// Options:
		'useHeadTitleByDefault' => true, // Get contents of headTitle() helper and bung into a property
		'useMetaDescriptionByDefault' => true, // The same for meta desc
		'addOgUrlByDefault' => true, // Add the full uri of the current request to 'og:url' prop
	),
);

Todo

As always... Tests...
OpenGraph Helper - Zend's HeadMeta helper will not render <meta property> tags with an HTML5 doctype - whilst they appear to be perfectly valid to me (W3C Validator allows it anyway) It would also be nice to have some concrete methods like addFacebookAdmin() for example
