Installation

The preferred way to install this extension is through composer.

Either run

$ php composer.phar require --prefer-dist simialbi/yii2-schema-org

or add

"simialbi/yii2-schema-org": "^2.0.0"

to the require section of your composer.json

Usage

In order to use this module, you will need to:

Configure your application so that the module is available.
Generate the Schemas you intend to use.

Setup Module

Configure the module named schema in the modules section of your Yii configuration file.

Remember to do this for console and for web application configuration file.

'modules' => [
	'schema' => [
		'class' => 'simialbi\yii2\schemaorg\Module',
		//'autoCreate' => false,
		//'autoRender' => false
	]
]

Also add the module schema to the bootstrap section of your configuration file:

'bootstrap' => ['log', 'schema']

If you don't use autoRender, be sure to manually call JsonLDHelper::render() in your layout file, like so:

<?php
/* @var $this \yii\web\View */
/* @var $content string */
use yii\helpers\Html;
use app\assets\AppAsset;
use simialbi\yii2\schemaorg\helpers\JsonLDHelper;

AppAsset::register($this);
?>
<?php $this->beginPage() ?>
<!DOCTYPE html>
<html lang="<?= Yii::$app->language ?>">
<head>
    <meta charset="<?= Yii::$app->charset ?>">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <?= Html::csrfMetaTags() ?>
    <title><?= Html::encode($this->title) ?></title>
    <?php JsonLDHelper::render(); ?>
    <?php $this->head() ?>
</head>

Model generation

Minimal (standard) configuration

Without passing any parameters all schemas will be generated in the folder @vendor/simialbi/yii2-schema-org/src/models. The namespace of the models will be simialbi\yii2\schemaorg\models.

$ php yii schema/models/generate

Customized

If you want to customize the namespace and path you can do it via --namespace and --folder parameters. E.g. to generate schemas Car and AutoDealer in common/schemas with common\schemas namespace:

$ php yii schema/models/generate 'latest' --schemas=Car,AutoDealer --namespace='common\schemas' --folder='@common/schemas/'

The console command will take care of computing schemas dependencies and will generate the classes based on your needs.

Automatic model update on composer update

If you'd like to always update your schema when you run composer update you can configure your composer.json like this:

{
  // [...]
  "require": {
    "yiisoft/yii2": "^2.0.13",
    "simialbi/yii2-schema-org": "^2.0.0"
  },
  "scripts": {
    "post-update-cmd": [
      "simialbi\\yii2\\schemaorg\\composer\\Installer::postInstallUpdate"
    ]
  },
  "extra": {
    "simialbi\\yii2\\schemaorg\\composer\\Installer::postInstallUpdate": {
      "generateModels": {
        "schemas": ["Car", "AutoDealer"], // optional
        "namespace": "common\\schemas", // optional
        "folder": "common/schema" // optional
      }
    }
  }
  // [...]
}

Example Usage

To e.g. add a person to json+ld, you can do the following:

use simialbi\yii2\schemaorg\helpers\JsonLDHelper;
use simialbi\yii2\schemaorg\models\Person;

$child = new Person();
$child->name = 'George W. Bush';
$child->disambiguatingDescription = '43rd President of the United States';
$person = new Person();
$person->name = 'George Bush';
$person->disambiguatingDescription = '41st President of the United States';
$person->children = [$child];

JsonLDHelper::add($person);
