Important

We are updating the images for OroCommerce version 6.1 to align with the latest changes in the back-office design. During this transition, some images may still show older versions. Thank you for your patience as we work to update all visuals to reflect these changes.

Validation for Extended Fields

By default, all extended fields are not validated. In general, extended fields are rendered as usual forms, the same way as not extended, but there is a way to define validation constraints for all extended fields by their type.

This is done through the configuration of oro_entity_extend.validation_loader:

oro_entity_extend.validation_loader:
    class: Oro\Bundle\EntityExtendBundle\Validator\ExtendFieldValidationLoader
    arguments:
        - '@oro_entity_config.provider.extend'
        - '@oro_entity_config.provider.form'
    calls:
        -
            - addConstraints
            -
                - integer
                -
                    - Regex:
                        pattern: '^(-?[1-9]\d*|0)$'
                        message: 'This value should contain only numbers.'

        - [addConstraints, ['percent', [{ Type: {type: 'numeric'} }]]]

There are two ways to pass the constraints:

• use a compiler pass to add the ‘addConstraints’ call with the necessary constraint configuration

• directly call the service

For example:

src/Acme/Bundle/DemoBundle/DependencyInjection/Compiler/AcmeExtendValidationPass.php

namespace Acme\Bundle\DemoBundle\DependencyInjection\Compiler;

use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;

class AcmeExtendValidationPass implements CompilerPassInterface
{
    private const INTEGER_CONSTRAINT = [
        'Regex' => [
            'pattern' => '/^(-?[1-9]\d*|0)$/',
            'message' => 'This value should contain only numbers!'
        ]
    ];

    #[\Override]
    public function process(ContainerBuilder $container): void
    {
        if (!$container->has('oro_entity_extend.validation_loader')) {
            return;
        }

        $definition = $container->findDefinition('oro_entity_extend.validation_loader');
        $definition->addMethodCall(
            'addConstraints',
            ['integer', [self::INTEGER_CONSTRAINT]]
        );
    }

Make sure to insert CompilerPass to the bundle root file.

src/Acme/Bundle/DemoBundle/AcmeDemoBundle.php

namespace Acme\Bundle\DemoBundle;
use Acme\Bundle\DemoBundle\DependencyInjection\Compiler\AcmeExtendValidationPass;
use Oro\Bundle\DataAuditBundle\Model\AuditFieldTypeRegistry;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\Bundle\Bundle;

class AcmeDemoBundle extends Bundle
{
    #[\Override]
    public function build(ContainerBuilder $container): void
    {
        parent::build($container);

        $container->addCompilerPass(new AcmeExtendValidationPass());
    }
}

Keep in mind that all constraints defined here are applied to all extended fields with a corresponding type.
