Property Details

actions property
public array $actions;

list of action IDs that this rule applies to. The comparison is case-insensitive.

allow property
public boolean $allow;

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

controllers property (available since v1.0.4)
public array $controllers;

list of controler IDs that this rule applies to. The comparison is case-insensitive.

expression property (available since v1.0.3)
public string $expression;

a PHP expression whose value indicates whether this rule should be applied. In this expression, you can use $user which refers to Yii::app()->user. Starting from version 1.0.11, the expression can also be a valid PHP callback, including class method name (array(ClassName/Object, MethodName)), or anonymous function (PHP 5.3.0+). The function/method will be passed a single parameter which is the user object.

ips property
public array $ips;

IP patterns.

roles property
public array $roles;

list of roles this rule applies to. For each role, the current user's CWebUser::checkAccess method will be invoked. If one of the invocations returns true, the rule will be applied. Note, you should mainly use roles in an "allow" rule because by definition, a role represents a permission collection.
