New in Symfony 4.1 Misc. improvements (part 3)

Allow to set the rounding strategy for MoneyType

Contributed by syastrebov in #26767

In Symfony 4.1, the MoneyType form field defines a new option called rounding_mode to control how the values are rounded. Before, all values were rounded towards "the nearest neighbor" (ROUND_HALF_UP) so 15.999 was rounded as 16.00. Now you can set it for example to ROUND_DOWN to display it as 15.99:

1
2
3
4
5
6
7

use Symfony\Component\Form\Extension\Core\DataTransformer\NumberToLocalizedStringTransformer;
use Symfony\Component\Form\Extension\Core\Type\MoneyType;
// ...

$builder->add('price', MoneyType::class, array(
    'rounding_mode' => NumberToLocalizedStringTransformer::ROUND_DOWN,
));

Adding and removing LDAP attributes more efficiently

Contributed by Jean-Guilhem Rouel in #21856

Updating LDAP entries with the update() is slow in some scenarios. That's why in Symfony 4.1 there are two new methods called addAttributeValues() and removeAttributeValues() that add/remove values to a multi-valued attribute:

1
2
3
4
5
6
7
8
9

use Symfony\Component\Ldap\Ldap;
 use Symfony\Component\Ldap\Entry;
 // ...

$entry = $ldap->query('...', '...')->execute()[0];

$entityManager = $ldap->getEntryManager();
$entityManager->addAttributeValues($entry, 'telephoneNumber', ['+1.111.222.3333', '+1.222.333.4444']);
$entityManager->removeAttributeValues($entry, 'telephoneNumber', ['+1.111.222.3333', '+1.222.333.4444']);

Keep query string after redirecting

Contributed by Hamza Amrouche in #26281

In Symfony 4.1, routes can define (in YAML, XML or PHP) a new option called keepQueryParams. By default it's false, but if you set it to true, the query parameters (if any) are added to the redirected URL:

1
2
3
4
5
6
7

legacy_search:
    path: /search-engine
    controller: Symfony\Bundle\FrameworkBundle\Controller\RedirectController::redirectAction
    defaults:
        route: search
        permanent: true
        keepQueryParams: true

In this example, if the original URL is /search-engine?q=symfony, the app redirects to /search?q=symfony

Added support for hasser accessors in PropertyInfo

Contributed by Sébastien Decrême in #23617

The PropertyInfo component introspects information about class properties by using different sources of metadata. In Symfony 4.1, one of those sources (the ReflectionExtractor class) added support for hasser methods.

This will allow for example to make a property readable by defining methods like hasChildren() instead of just getChildren().
