Ip

Validates that a value is a valid IP address. By default, this will validate the value as IPv4, but a number of different options exist to validate as IPv6 and many other combinations.

Applies to

property or method

Class

Symfony\Component\Validator\Constraints\Ip

Validator

Symfony\Component\Validator\Constraints\IpValidator

Basic Usage

Note

As with most of the other constraints, null and empty strings are considered valid values. This is to allow them to be optional values. If the value is mandatory, a common solution is to combine this constraint with NotBlank.

Options

groups

type: array | string

It defines the validation group or groups of this constraint. Read more about validation groups.

message

type: string default: This is not a valid IP address.

This message is shown if the string is not a valid IP address.

You can use the following parameters in this message:

Parameter

Description

{{ value }}

The current (invalid) value

{{ label }}

Corresponding form field label

New in version 5.2: The {{ label }} parameter was introduced in Symfony 5.2.

normalizer

type: a PHP callable default: null

This option allows to define the PHP callable applied to the given value before checking if it is valid.

For example, you may want to pass the 'trim' string to apply the :phpfunction:`trim` PHP function in order to ignore leading and trailing whitespace during validation.

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.
