Inheritanceyii\validators\IpValidator » yii\validators\Validator » yii\base\Component » yii\base\BaseObject
Implementsyii\base\Configurable
Available since version2.0.7
Source Code https://github.com/yiisoft/yii2/blob/master/framework/validators/IpValidator.php

The validator checks if the attribute value is a valid IPv4/IPv6 address or subnet.

It also may change attribute's value if normalization of IPv6 expansion is enabled.

The following are examples of validation rules using this validator:

['ip_address', 'ip'], // IPv4 or IPv6 address
['ip_address', 'ip', 'ipv6' => false], // IPv4 address (IPv6 is disabled)
['ip_address', 'ip', 'subnet' => true], // requires a CIDR prefix (like 10.0.0.1/24) for the IP address
['ip_address', 'ip', 'subnet' => null], // CIDR prefix is optional
['ip_address', 'ip', 'subnet' => null, 'normalize' => true], // CIDR prefix is optional and will be added when missing
['ip_address', 'ip', 'ranges' => ['192.168.0.0/24']], // only IP addresses from the specified subnet are allowed
['ip_address', 'ip', 'ranges' => ['!192.168.0.0/24', 'any']], // any IP is allowed except IP in the specified subnet
['ip_address', 'ip', 'expandIPv6' => true], // expands IPv6 address to a full notation format

clientValidateAttribute() public method

$model
$attribute
$view
getClientOptions() public method

{@inheritdoc}

public void getClientOptions ( $model, $attribute )
$model
$attribute
getRanges() public method

public array getRanges ( )
return array

The IPv4 or IPv6 ranges that are allowed or forbidden.
init() public method

{@inheritdoc}

public void init ( )
setRanges() public method

Set the IPv4 or IPv6 ranges that are allowed or forbidden.

The following preparation tasks are performed:

  • Recursively substitutes aliases (described in $networks) with their values.
  • Removes duplicates
public void setRanges ( $ranges )
$ranges array|string

The IPv4 or IPv6 ranges that are allowed or forbidden.

When the array is empty, or the option not set, all IP addresses are allowed.

Otherwise, the rules are checked sequentially until the first match is found. An IP address is forbidden, when it has not matched any of the rules.

Example:

[
     'ranges' => [
         '192.168.10.128'
         '!192.168.10.0/24',
         'any' // allows any other IP addresses
     ]
]

In this example, access is allowed for all the IPv4 and IPv6 addresses excluding the 192.168.10.0/24 subnet. IPv4 address 192.168.10.128 is also allowed, because it is listed before the restriction.
