NotIdenticalTo ============== Validates that a value is **not** identical to another value, defined in the options. To force that a value is identical, see :doc:`/reference/constraints/IdenticalTo`. .. caution:: This constraint compares using ``!==``, so ``3`` and ``"3"`` are considered not equal. Use :doc:`/reference/constraints/NotEqualTo` to compare with ``!=``. ========== =================================================================== Applies to :ref:`property or method ` Options - `groups`_ - `message`_ - `payload`_ - `propertyPath`_ - `value`_ Class :class:`Symfony\\Component\\Validator\\Constraints\\NotIdenticalTo` Validator :class:`Symfony\\Component\\Validator\\Constraints\\NotIdenticalToValidator` ========== =================================================================== Basic Usage ----------- The following constraints ensure that: * ``firstName`` of ``Person`` is not equal to ``Mary`` *or* not of the same type * ``age`` of ``Person`` class is not equal to ``15`` *or* not of the same type .. configuration-block:: .. code-block:: php-annotations // src/Entity/Person.php namespace App\Entity; use Symfony\Component\Validator\Constraints as Assert; class Person { /** * @Assert\NotIdenticalTo("Mary") */ protected $firstName; /** * @Assert\NotIdenticalTo( * value = 15 * ) */ protected $age; } .. code-block:: yaml # config/validator/validation.yaml App\Entity\Person: properties: firstName: - NotIdenticalTo: Mary age: - NotIdenticalTo: value: 15 .. code-block:: xml Mary .. code-block:: php // src/Entity/Person.php namespace App\Entity; use Symfony\Component\Validator\Constraints as Assert; use Symfony\Component\Validator\Mapping\ClassMetadata; class Person { public static function loadValidatorMetadata(ClassMetadata $metadata) { $metadata->addPropertyConstraint('age', new Assert\NotIdenticalTo('Mary')); $metadata->addPropertyConstraint('age', new Assert\NotIdenticalTo([ 'value' => 15, ])); } } Options ------- .. include:: /reference/constraints/_groups-option.rst.inc ``message`` ~~~~~~~~~~~ **type**: ``string`` **default**: ``This value should not be identical to {{ compared_value_type }} {{ compared_value }}.`` This is the message that will be shown if the value is identical.
