Property Details

$actions public property

List of action IDs that this rule applies to. The comparison is case-sensitive. If not set or empty, it means this rule applies to all actions.

public array $actions null
$allow public property

Whether this is an 'allow' rule or 'deny' rule.

public boolean $allow null
$controllers public property

List of the controller IDs that this rule applies to.

The comparison uses yii\base\Controller::uniqueId, so each controller ID is prefixed with the module ID (if any). For a product controller in the application, you would specify this property like ['product'] and if that controller is located in a shop module, this would be ['shop/product'].

The comparison is case-sensitive.

If not set or empty, it means this rule applies to all controllers.

Since version 2.0.12 controller IDs can be specified as wildcards, e.g. module/*.

public array $controllers null
$denyCallback public property

A callback that will be called if this rule determines the access to the current action should be denied. This is the case when this rule matches and $allow is set to false.

If not set, the behavior will be determined by yii\filters\AccessControl, either using yii\filters\AccessControl::denyAccess() or yii\filters\AccessControl::$denyCallback, if configured.

The signature of the callback should be as follows:

function ($rule, $action)

where $rule is this rule, and $action is the current action object.

See also yii\filters\AccessControl::$denyCallback.

public callable $denyCallback null
$ips public property

List of user IP addresses that this rule applies to. An IP address can contain the wildcard * at the end so that it matches IP addresses with the same prefix. For example, '192.168.*' matches all IP addresses in the segment '192.168.'. If not set or empty, it means this rule applies to all IP addresses.

See also yii\web\Request::userIP.

public array $ips null
$matchCallback public property

A callback that will be called to determine if the rule should be applied. The signature of the callback should be as follows:

function ($rule, $action)

where $rule is this rule, and $action is the current action object. The callback should return a boolean value indicating whether this rule should be applied.

public callable $matchCallback null
$permissions public property (available since version 2.0.12)

List of RBAC (Role-Based Access Control) permissions that this rules applies to. yii\web\User::can() will be called to check access.

If this property is not set or empty, it means this rule applies regardless of permissions.

See also:

public array $permissions null
$roleParams public property (available since version 2.0.12)

Parameters to pass to the yii\web\User::can() function for evaluating user permissions in $roles.

If this is an array, it will be passed directly to yii\web\User::can(). For example for passing an ID from the current request, you may use the following:

['postId' => Yii::$app->request->get('id')]

You may also specify a closure that returns an array. This can be used to evaluate the array values only if they are needed, for example when a model needs to be loaded like in the following code:

'rules' => [
    [
        'allow' => true,
        'actions' => ['update'],
        'roles' => ['updatePost'],
        'roleParams' => function($rule) {
            return ['post' => Post::findOne(Yii::$app->request->get('id'))];
        },
    ],
],

A reference to the yii\filters\AccessRule instance will be passed to the closure as the first parameter.

See also $roles.

$roles public property

List of roles that this rule applies to (requires properly configured User component). Two special roles are recognized, and they are checked via yii\web\User::isGuest:

  • ?: matches a guest user (not authenticated yet)
  • @: matches an authenticated user

If you are using RBAC (Role-Based Access Control), you may also specify role names. In this case, yii\web\User::can() will be called to check access.

Note that it is preferred to check for permissions instead.

If this property is not set or empty, it means this rule applies regardless of roles.

See also:

public array $roles null
$verbs public property

List of request methods (e.g. GET, POST) that this rule applies to. If not set or empty, it means this rule applies to all request methods.

See also yii\web\Request::method.

public array $verbs null
