A Fluent Builder For Schema.org Types And ld+json Generator
spatie/schema-org
provides a fluent builder for all Schema.org types and their properties. The code in src
is generated from Schema.org's RFDa standards file, so it provides objects and methods for the entire core vocabulary. The classes and methods are also fully documented as a quick reference.
use Spatie\SchemaOrg\Schema;
$localBusiness = Schema::localBusiness()
->name('Spatie')
->email('info@spatie.be')
->contactPoint(Schema::contactPoint()->areaServed('Worldwide'));
$localBusiness->toScript();
<script type="application/ld+json">
{
"@context": "http:\/\/schema.org",
"@type": "LocalBusiness",
"name": "Spatie",
"email": "info@spatie.be",
"contactPoint": {
"@type": "ContactPoint",
"areaServed": "Worldwide"
}
}
</script>
Installation
You can install the package via composer:
composer require spatie/schema-org
Usage
All types can be instantiated though the Spatie\SchemaOrg\Schema
factory class, or with the new
keyword.
$localBusiness = Schema::localBusiness()->name('Spatie');
// Is equivalent to:
$localBusiness = new LocalBusiness();
$localBusiness->name('Spatie');
All types also accept arrays of the expected data type, for example
sameAs
accepts a string or an array of strings.
All types also implement the SPL's ArrayAccess
for accessing the properties via array notation:
$anotherLocalBusiness = new LocalBusiness();
var_dump(isset($anotherLocalBusiness['name'])); // => false
$anotherLocalBusiness['name'] = 'Spatie';
var_dump(isset($anotherLocalBusiness['name'])); // => true
var_dump($anotherLocalBusiness['name']); // => 'Spatie'
unset($anotherLocalBusiness['name']);
var_dump(isset($anotherLocalBusiness['name'])); // => false
Types can be converted to an array or rendered to a script.
$localBusiness->toArray();
$localBusiness->toScript();
echo $localBusiness; // Same output as `toScript()`
Additionally, all types can be converted to a plain JSON string by just calling json_encode()
with your object:
echo json_encode($localBusiness);
Enumerations
As of v1.6.0, all Enumeration child types are available as classes with constants.
Schema::book()->bookFormat(Spatie\Schema\BookFormatType::Hardcover);
There's no full API documentation for types and properties. You can refer to the source or to the schema.org website.
If you don't want to break the chain of a large schema object, you can use the if
method to conditionally modify the schema.
use Spatie\SchemaOrg\LocalBusiness;
use Spatie\SchemaOrg\Schema;
$business = ['name' => 'Spatie'];
$localBusiness = Schema::localBusiness()
->name($business['name'])
->if(isset($business['email']), function (LocalBusiness $schema) {
$schema->email($business['email']);
});
I recommended double checking your structured data with Google's structured data testing tool
Advanced Usage
If you'd need to set a custom property, you can use the setProperty
method.
$localBusiness->setProperty('foo', 'bar');
If you'd need to retrieve a property, you can use the getProperty
method. You can optionally pass in a second parameter to provide a default value.
$localBusiness->getProperty('name'); // 'Spatie'
$localBusiness->getProperty('bar'); // null
$localBusiness->getProperty('bar', 'baz'); // 'baz'
All properties can be retrieved as an array with the getProperties
method.
$localBusiness->getProperties(); // ['name' => 'Spatie', ...]
Multiple properties can be set at once using the addProperties
method.
$localBusiness->addProperties(['name' => 'value', 'foo' => 'bar']);
Context and type can be retrieved with the getContext
and getType
methods.
$localBusiness->getContext(); // 'http://schema.org'
$localBusiness->getType(); // 'LocalBusiness'
Graph - multiple items
The Graph has a lot of methods and utilities - the type-safe and simplest way is to use the overloaded methods of the Spatie\SchemaOrg\Schema
class itself. These methods will get an already created or new instance of the requested schema.
$graph = new Graph();
// Create a product and prelink organization
$graph
->product()
->name('My cool Product')
->brand($graph->organization());
// Hide the organization from the created script tag
$graph->hide(\Spatie\SchemaOrg\Organization::class);
// Somewhere else fill out the organization
$graph
->organization()
->name('My awesome Company');
// Render graph to script tag
echo $graph;
With these tools the graph is a collection of all available schemas, can link these schemas with each other and prevent helper schemas from being rendered in the script-tag.
Known Issues
Type Inheritance
The spec rdfa document that's used to generate this code uses single inheritance for the types. However, the spec on http://schema.org uses multiple inheritance in some cases. Read the docs and use Google's structured data testing tool to ensure you're on the right track!
For example, according to the rdfa, a LocalBusiness
inherits properties from Organization
. However, if you visit the spec page on Schema.org, it inherits properties from Organization
and Place
. The current solution is by manually specifying properties on the item, as described above in advanced usage.
Schema::localBusiness()
// `address` is part of `Organization`, so the method exists
->address(/* ... */)
// `openingHoursSpecification` is part of `Place`, so we need to manually add it
->setProperty('openingHoursSpecification', /* ... */);
Other Minor Issues
- The
Float
type isn't available since it's a reserved keyword in PHP - The
Physician
type isn't available since it extends a type from thehealth
extension spec
