Quick Example
Business
$context = \JsonLd\Context::create('local_business', [
'name' => 'Consectetur Adipiscing',
'description' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor',
'telephone' => '555-555-5555',
'openingHours' => 'mon,tue,fri',
'address' => [
'streetAddress' => '112 Apple St.',
'addressLocality' => 'Hamden',
'addressRegion' => 'CT',
'postalCode' => '06514',
],
'geo' => [
'latitude' => '41.3958333',
'longitude' => '-72.8972222',
],
]);
echo $context; // Will output the script tagNews Article
$context = \JsonLd\Context::create('news_article', [
'headline' => 'Article headline',
'description' => 'A most wonderful article',
'mainEntityOfPage' => [
'url' => 'https://google.com/article',
],

'height' => 800,
'width' => 800,
],
'datePublished' => '2015-02-05T08:00:00+08:00',

'name' => 'Google',
'logo' => [
'url' => 'https://google.com/logo.jpg',
'width' => 600,
'height' => 60,
]
],
]);
echo $context; // Will output the script tagUsing the JSON-LD in a Laracasts Presenter
Even though this example shows using the JSON-LD inside of a Laracasts\Presenter presenter, Laravel is not required for this package.
/App/Presenters/BusinessPresenter.php
<?php
namespace App\Presenters;
use JsonLd\Context;
use Laracasts\Presenter\Presenter;
class BusinessPresenter extends Presenter
{
/**
* Create JSON-LD object.
*
* @return \JsonLd\Context
*/
public function jsonLd()
{
return Context::create('local_business', [
'name' => $this->entity->name,
'description' => $this->entity->description,
'telephone' => $this->entity->telephone,
'openingHours' => 'mon,tue,fri',
'address' => [
'streetAddress' => $this->entity->address,
'addressLocality' => $this->entity->city,
'addressRegion' => $this->entity->state,
'postalCode' => $this->entity->postalCode,
],
'geo' => [
'latitude' => $this->entity->location->lat,
'longitude' => $this->entity->location->lng,
],
]);
}
}Generate the Tags
The generator comes with a __toString method that will automatically generate the correct script tags when displayed as a string.
Inside of a Laravel View
echo $business->present()->jsonLd();Inside of a Laravel View
{!! $business->present()->jsonLd() !!}
Custom Context Type
The first argument for the create($context, array $data = []) method also accepts class names. This is helpful for custom context types.
<?php
namespace App\JsonLd;
use JsonLd\ContextTypes\AbstractContext;
class FooBar extends AbstractContext
{
/**
* Property structure
*
* @var array
*/
protected $structure = [
'name' => null,
'description' => null,
'image' => null,
'url' => null,
];
}$context = \JsonLd\Context::create(\App\JsonLd\FooBar::class, [
'name' => 'Foo Foo headline',
'description' => 'Bar bar article description',
'url' => 'http://google.com',
]);
echo $context; // Will output the script tag
