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

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