Creates a Symfony form from a JSON schema.

Installation:

With Composer:

composer require cyve/json-schema-form-bundle

Usage

use Cyve\JsonSchemaFormBundle\Form\Type\SchemaType;
use Cyve\JsonSchemaFormBundle\Validator\Constraint\Schema;

$json = <<<JSON
{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "$id": "http://example.com/product.schema.json",
  "title": "Product",
  "type": "object",
  "properties": {
    "id": {
      "type": "integer"
    },
    "name": {
      "type": "string"
    }
  },
  "required": ["id", "name"]
}
JSON;
$schema = json_decode($json);
$subject = new \StdClass();
$form = $container->get('form.factory')->create(SchemaType::class, $subject, ['data_schema' => $schema, 'constraints' => [new Schema($schema)]]);

The form option data_schema MUST be an object representing a JSON schema.

Validation

To validate the form subject against the JSON schema, add the form option 'constraints' => [new Cyve\JsonSchemaFormBundle\Validator\Constraint\Schema($schema)] to the root form. The validator uses propertyPath to display the violation messages on the proper fields.
The JSON schema validation is made using justinrainbow/json-schema.
