OG Data

This library provides a set of interfaces which when implemented on your domain objects can be used to generate OGP data.

You can find the code example shown below in the example directory.

Below is the code required to convert our 2 domain objects(Movie and Person) into HTML ready OGP data.

<?php

use Acme\Movie;
use Acme\Person;

// Set up some auto loading
$autoloader = require __DIR__ . '/../vendor/autoload.php';
$autoloader->addPsr4('Acme\\', __DIR__ . '/Acme/');

// Create the directors and writers for our Movie
$director = new Person('Robert', 'Schwentke', 'male');
$writers = [
    new Person('Bruce',  'Rubin', 'male'),
    new Person('Audrey',  'Niffenegger', 'female'),
];

// Create our movie
$movie =  new Movie([], $director, 6480, new \DateTime('August 14, 2009'), $writers, []);


$renderer = new \Baileylo\Ogp\Render();
$properties = $renderer->render($movie);

foreach($properties as $property) {
    echo sprintf('<meta property="%s" content="%s" />', $property->property, $property->content) . PHP_EOL;
}

This will generate the following output:

<meta property="og:type" content="video.movie" />
<meta property="video:duration" content="6480" />
<meta property="video:release_date" content="2009-08-14T00:00:00-0700" />
<meta property="video:director:first_name" content="Robert" />
<meta property="video:director:last_name" content="Schwentke" />
<meta property="video:director:gender" content="male" />
<meta property="video:writer:first_name" content="Bruce" />
<meta property="video:writer:last_name" content="Rubin" />
<meta property="video:writer:gender" content="male" />
<meta property="video:writer:first_name" content="Audrey" />
<meta property="video:writer:last_name" content="Niffenegger" />
<meta property="video:writer:gender" content="female" />
