IdenticalTo
Edit this pageWarning: You are browsing the documentation for Symfony 3.0, which is no longer maintained.
Read the updated version of this page for Symfony 6.3 (the current stable version).
IdenticalTo
Validates that a value is identical to another value, defined in the options. To force that a value is not identical, see NotIdenticalTo.
Caution
This constraint compares using ===, so 3 and "3" are not
considered equal. Use EqualTo to compare
with ==.

Basic Usage
The following constraints ensure that:
firstNameofPersonclass is equal toMaryand is a stringageis equal to20and is of type integer
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
// src/AppBundle/Entity/Person.php
namespace AppBundle\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class Person
{
/**
* @Assert\IdenticalTo("Mary")
*/
protected $firstName;
/**
* @Assert\IdenticalTo(
* value = 20
* )
*/
protected $age;
}Options
value
type: mixed [default option]
This option is required. It defines the value to compare to. It can be a string, number or object.
message
type: string default: This value should be identical to {{ compared_value_type }} {{ compared_value }}.
This is the message that will be shown if the value is not identical.
payload
type: mixed default: null
This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to you.
For example, you may want to use several error levels to present failed constraints differently in the front-end depending on the severity of the error.
