Entity validator for Doctrine ORM 3

By default, entity validation based on attached \Doctrine\ORM\Mapping\Column attributes and attributes inherited ColumnValidator interface.

Also, you can add custom validators by EntityValidator::addValidator() or create instance of ColumnValidator interface.

Validator skip validation:

• If Column attribute declared as not updatable and/or insertable
• Validation on persist/insert and property have \Doctrine\ORM\Mapping\Id attribute

Validator checks by column type:

• If property value is null (or not defined), but Column attribute not declared as nullable or/and don't have default value (options: ['default' => '...'])
• If Column attribute have numeric type (integer, float, decimal and etc.):
  • If defined unsigned option, then property value must be more than zero
  • If type decimal and defined precision, then check size of value
• If Column attribute have string type (sting, text and etc.):
  • If defined fixed option and length, then check string length
  • If defined only length, then check string length
• If Column attribute have enum type:
  • If defined enumType, then check is proprerty value is declared in enum class

ColumnValidator attributes:

• MinLength
• Greater
• Number
• Regexp
• Type
• Filter
• Slug
• Ip
• Url
• Email

Events

The postValidate(EntityValidator::EVENT_POST_VALIDATE) event triggers after successful validation, the syntax of listener method: function (LifecycleEventArgs $args): void.

Examples

Validates Product entity before insert/update data:

use Doctrine\DBAL\Types\Types;
use Doctrine\ORM\Mapping as ORM;
use \EnsoStudio\Doctrine\ORM\ColumnValidators;
use EnsoStudio\Doctrine\ORM\EntityValidator;
use EnsoStudio\Doctrine\ORM\EntityValidationException;

#[ORM\Entity]
#[ORM\Table(name: 'products')]
#[ORM\HasLifecycleCallbacks]
class Product
{
    ...

    #[ORM\Column(type: Types::STRING, length: 200)]
    #[ColumnValidators\MinLength(2)]
    #[ColumnValidators\Slug]
    private string $slug;

    #[ORM\Column(type: Types::STRING, length: 150)]
    #[ColumnValidators\Type('print')]
    private string $name;

    #[ORM\PrePersist]
    public function beforeInsert(): void
    {
        $validator = new EntityValidator($this);
        // Callback same to ColumnValidators\MinLength(3)
        $validator->addValidator(
            'name', 
            static function (string $propertyValue, string $propertyName, object $entity) {
                if (mb_strlen($propertyValue) < 3) {
                    throw new EntityValidationException(
                        ['% less than 3 characters', $propertyName],
                        $propertyName,
                        $entity
                    );
                }
            }
        );
        $validator->validate();
    }

    #[ORM\PreUpdate]
    public function beforeUpdate(): void
    {
        $validator = new EntityValidator($this);
        ...
        $validator->validate(true);
    }
}

Or you can use EntityValidationSubscriber to validates all entities:

use Doctrine\ORM\EntityManager;
use EnsoStudio\Doctrine\ORM\EntityValidationSubscriber;

...
$entityManager = new EntityManager($connection, $config);
$entityManager->getEventManager()
    ->addEventSubscriber(new EntityValidationSubscriber(true));

Requirements

• PHP >= 8.1 (with mbstring extension)
• doctrine/orm >= 3.3
