PHP Class yii\filters\AccessControl

AccessControl is an action filter. It will check its [[rules]] to find the first rule that matches the current context variables (such as user IP address, user role). The matching rule will dictate whether to allow or deny the access to the requested controller action. If no rule matches, the access will be denied. To use AccessControl, declare it in the behaviors() method of your controller class. For example, the following declarations will allow authenticated users to access the "create" and "update" actions and deny all other users from accessing these two actions. php public function behaviors() { return [ 'access' => [ 'class' => \yii\filters\AccessControl::className(), 'only' => ['create', 'update'], 'rules' => [ deny all POST requests [ 'allow' => false, 'verbs' => ['POST'] ], allow authenticated users [ 'allow' => true, 'roles' => ['@'], ], everything else is denied ], ], ]; }

Public Properties

Property	Type	Description
$denyCallback		a callback that will be called if the access should be denied to the current user. If not set, AccessControl::denyAccess will be called. The signature of the callback should be as follows: php function ($rule, $action) where $rule is the rule that denies the user, and $action is the current [[Action\|action]] object. $rule can be null if access is denied because none of the rules matched.
$ruleConfig		the default configuration of access rules. Individual rule configurations specified via [[rules]] will take precedence when the same property of the rule is configured.
$rules		a list of access rule objects or configuration arrays for creating the rule objects. If a rule is specified via a configuration array, it will be merged with [[ruleConfig]] first before it is used for creating the rule object.
$user		the user object representing the authentication status or the ID of the user application component. Starting from version 2.0.2, this can also be a configuration array for creating the object.
