Symfony Framework Integration

Symfony is a PHP framework for web applications and a set of reusable PHP components. Integration for RollerworksSearch in a Symfony application, is provided using the RollerworksSearchBundle.

You need the Symfony FrameworkBundle and optionally Symfony Flex, while not required the following examples assume your using at least Symfony 3.4 and have Symfony Flex installed.

All RollerworksSearch services can be autowired. There service-id’s are shown for reference.

Note

If your new to Symfony, it’s a really good idea to learn about the basics of Symfony first.

These examples assume you know how to work with services, create Controllers and know how to change your app’s configuration.

Installation

Following the installation instructions install the symfony Bundle by running:

$ php composer.phar require rollerworks/search-bundle

Tip

Install the RollerworksSearch Symfony InputValidator extension to utilize validation constraints in your input.

Make sure the framework.validator is enabled in your application’s configuration, unless explicitly disabled this should be automatically enabled.

Basic usage

The purpose of the bundle is to integrate RollerworksSearch into your Symfony application. Because of this most of RollerworksSearch’s documentation can be used as-is.

The main difference is that the integration is already done for you, and you use the service Container instead of initializing classes yourself.

SearchFactory

Get the (default) SearchFactory service using rollerworks_search.factory:

...

$searchFactory = $container->get('rollerworks_search.factory');

$fieldSetBuilder = $searchFactory->createFieldSetBuilder();
$userFieldSet = $searchFactory->createFieldSet(UserFieldSet::class);

$serializer = $searchFactory->getSerializer();
$serializedCondition = $serializer->serialize($searchCondition);
$searchCondition = $serializer->unserialize($serializedCondition);

That’s it. You can now process search requests! See the reference section below to learn more about application wide cache configuring.

Registering types and type extensions

Registering types is only needed when they have injection dependencies (constructor or setter). Type extensions always need to be registered.

Note

Tagging is only required if autoconfigure is not enabled, for the current file.

To register a type, create a service as normal and tag it as rollerworks_search.type.

Condition processors

Second to SearchFactory and SearchProcessor the bundle provides an integration all build-in condition processors (Doctrine DBAL) and Elasticsearch.

Doctrine integration

Doctrine integration requires the DoctrineBundle is installed and properly configured.

See Doctrine integration for more information on usage details.

$ composer require --no-update "doctrine/doctrine-bundle"
$ composer require --no-update "rollerworks/search-doctrine-dbal"
$ composer update

To install the ORM extension run:

$ composer require "rollerworks/search-doctrine-orm:^2.0"

That’s it, the extensions are automatically detected and enabled. To disable/enable the extension use the following:

  • YAML
    1
2
3
4
5
    rollerworks_search:
    doctrine:
        dbal:
            enabled: true
        orm: false # same as ` { enabled: false } `
  • PHP
    1

    /** @var $container \Symfony\Component\DependencyInjection\ContainerBuilder */
$container->loadFromExtension('rollerworks_search', [
    'doctrine' => [
        'orm' => ['enabled' => true],
        'orm' => true,
    ],
]);

Note

The DBAL extension cannot be disabled when ORM extension is enabled.

Basic Usage

Usage of the Doctrine extensions is as you expect, both the DBAL and ORM factories are automatically registered:

1

5
// \Rollerworks\Component\Search\Doctrine\Dbal\DoctrineDbalFactory
$doctrineDbalFactory = $container->get('rollerworks_search.doctrine_dbal.factory');

// \Rollerworks\Component\Search\Doctrine\Orm\DoctrineOrmFactory
$doctrineOrmFactory = $container->get('rollerworks_search.doctrine_orm.factory');

Enable Caching

By default the Doctrine integration doesn’t have caching enabled, to enable caching of generated query conditions configure the rollerworks_search.doctrine.cache pool.

  • YAML
    1
2
3
4
    framework:
    cache:
        rollerworks_search.doctrine.cache:
            adapter: ...
  • PHP

    /** @var $container \Symfony\Component\DependencyInjection\ContainerBuilder */
$container->prependExtensionConfig('framework', [
    'cache' => [
        'pools' => [
            'rollerworks_search.doctrine.cache' => [
                'adapter' => ...,
            ],
        ],
    ],
]);

Caution

Don’t use the cache.system (Filesystem) adapter but instead use a Redis/Memcache adapter for best performance.
