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
Options	groups message normalizer payload version
Class	`Ip`
Validator	`IpValidator`

Basic Usage¶

Annotations

// src/Entity/Author.php
namespace App\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Author
{
    /**
     * @Assert\Ip
     */
    protected $ipAddress;
}

YAML

# config/validator/validation.yaml
App\Entity\Author:
    properties:
        ipAddress:
            - Ip: ~

XML

<!-- config/validator/validation.xml -->
<?xml version="1.0" encoding="UTF-8" ?>
<constraint-mapping xmlns="http://symfony.com/schema/dic/constraint-mapping"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://symfony.com/schema/dic/constraint-mapping https://symfony.com/schema/dic/constraint-mapping/constraint-mapping-1.0.xsd">

    <class name="App\Entity\Author">
        <property name="ipAddress">
            <constraint name="Ip"/>
        </property>
    </class>
</constraint-mapping>

PHP

// src/Entity/Author.php
namespace App\Entity;

use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\Mapping\ClassMetadata;

class Author
{
    public static function loadValidatorMetadata(ClassMetadata $metadata)
    {
        $metadata->addPropertyConstraint('ipAddress', new Assert\Ip());
    }
}

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 this constraint belongs to. 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

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 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.

version¶

type: string default: 4

This determines exactly how the IP address is validated and can take one of a variety of different values:

All ranges

4: Validates for IPv4 addresses
6: Validates for IPv6 addresses
all: Validates all IP formats

No private ranges

4_no_priv: Validates for IPv4 but without private IP ranges
6_no_priv: Validates for IPv6 but without private IP ranges
all_no_priv: Validates for all IP formats but without private IP ranges

No reserved ranges

4_no_res: Validates for IPv4 but without reserved IP ranges
6_no_res: Validates for IPv6 but without reserved IP ranges
all_no_res: Validates for all IP formats but without reserved IP ranges

Only public ranges

4_public: Validates for IPv4 but without private and reserved ranges
6_public: Validates for IPv6 but without private and reserved ranges
all_public: Validates for all IP formats but without private and reserved ranges
