AccessControl extends ActionFilter
in package

Application

Handles the AccessControl for a Controller.

Controller level AccessRules can be provided by either setting the [[rules]] array, or by implementing a getAccessRules() function within the controller itself (prefered).

Examples:

Disable guest access for all controller actions:

protected function getAccessRules()
{
    return [
         ['login']
    ];
}

Disable guest access for specific controller actions:

protected function getAccessRules()
{
    return [
         ['login' => ['action1', 'action2']]
    ];
}

All users have to be logged in + additional permission check for 'action1' and 'action2':

protected function getAccessRules()
{
    return [
         ['login'],
         ['permission' => MyPermission::class, 'actions' => ['action1', 'action2']]
    ];
}

Custom inline validator for action 'action1':

protected function getAccessRules()
{
    return [
         ['validateMyCustomRule', 'someParameter' => 'someValue', 'actions' => ['action1']]
    ];
}

public function validateMyCustomRule($rule, $access)
{
    if($rule['someParameter'] !== 'someValue') {
         $access->code = 401;
         $access->reason = 'Not authorized!';
         return false;
    }

     return true;
}

The list of available rules is given by the [[\humhub\components\access\ControllerAccess]] class set by a controller. By default the base [[\humhub\components\access\ControllerAccess]] class will be used.

The default ControllerAccess class can be overwritten by implementing the getAccess() function within a controller, which should return an instance of ControllerAccess.

Note: You can also use the [[\humhub\components\Controller::access]] property to define a ControllerAccess class string.

$adminOnly

Only allow admins access to this controller


    public
        bool
    $adminOnly
     = false

$except


    public
        array<string|int, mixed>
    $except
     = []

list of action IDs that this filter should not apply to.

$guestAllowedActions

Action ids which are allowed when Guest Mode is enabled


    public
        array<string|int, mixed>
    $guestAllowedActions
     = []

$loggedInOnly

Only allow logged in users access to this controller


    public
        mixed

     = false

$only


    public
        array<string|int, mixed>
    $only
     = []

list of action IDs that this filter should apply to. If this property is not set, then the filter applies to all actions, unless they are listed in [[except]]. If an action ID appears in both [[only]] and [[except]], this filter will NOT apply to it.

Note that if the filter is attached to a module, the action IDs should also include child module IDs (if any) and controller IDs.

Since version 2.0.9 action IDs can be specified as wildcards, e.g. site/*.

$owner


    public
        Component|null
    $owner

the owner of this behavior

$rules

Rules for access to controller


    public
        array<string|int, mixed>
    $rules
     = null

__call()

Calls the named method which is not a class method.


    public
                    __call(string $name, array<string|int, mixed> $params) : mixed

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

Parameters

$name : string: the method name
$params : array<string|int, mixed>: method parameters

Return values

mixed —

the method return value

__construct()

Constructor.


    public
                    __construct([array<string|int, mixed> $config = [] ]) : mixed

The default implementation does two things:

Initializes the object with the given configuration $config.
Call [[init()]].

If this method is overridden in a child class, it is recommended that

the last parameter of the constructor is a configuration array, like $config here.
call the parent implementation at the end of the constructor.

Parameters

$config : array<string|int, mixed> = []: name-value pairs that will be used to initialize the object properties

__get()

Returns the value of an object property.


    public
                    __get(string $name) : mixed

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $object->property;.

Parameters

$name : string: the property name

Return values

mixed —

the property value

__isset()

Checks if a property is set, i.e. defined and not null.


    public
                    __isset(string $name) : bool

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($object->property).

Note that if the property is not defined, false will be returned.

Parameters

$name : string: the property name or the event name

Return values

bool —

whether the named property is set (not null).

__set()

Sets value of an object property.


    public
                    __set(string $name, mixed $value) : mixed

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $object->property = $value;.

Parameters

$name : string: the property name or the event name
$value : mixed: the property value

__unset()

Sets an object property to null.


    public
                    __unset(string $name) : mixed

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing unset($object->property).

Note that if the property is not defined, this method will do nothing. If the property is read-only, it will throw an exception.

Parameters

$name : string: the property name

afterAction()

This method is invoked right after an action is executed.


    public
                    afterAction(Action $action, mixed $result) : mixed

You may override this method to do some postprocessing for the action.

Parameters

$action : Action: the action just executed.
$result : mixed: the action execution result

Return values

mixed —

the processed action result.

afterFilter()


    public
                    afterFilter(ActionEvent $event) : mixed

                    attach(mixed $owner) : mixed

Parameters

$owner : mixed: the component that this behavior is to be attached to.

beforeAction()

This method is invoked right before an action is to be executed (after all possible filters.) You may override this method to do last-minute preparation for the action.


    public
                    beforeAction(mixed $action) : bool

Parameters

$action : mixed: the action to be executed.

Return values

bool —

whether the action should continue to be executed.

beforeFilter()


    public
                    beforeFilter(ActionEvent $event) : mixed

Returns a value indicating whether a property can be read.


    public
                    canGetProperty(string $name[, bool $checkVars = true ]) : bool

A property is readable if:

the class has a getter method associated with the specified name (in this case, property name is case-insensitive);
the class has a member variable with the specified name (when $checkVars is true);

Parameters

$name : string: the property name
$checkVars : bool = true: whether to treat member variables as properties

Return values

bool —

whether the property can be read

the fully qualified name of this class.

detach()

Detaches the behavior object from the component.


    public
                    detach() : mixed

events()

Declares event handlers for the [[owner]]'s events.


    public
                    events() : array<string|int, mixed>

Child classes may override this method to declare what PHP callbacks should be attached to the events of the [[owner]] component.

The callbacks will be attached to the [[owner]]'s events when the behavior is attached to the owner; and they will be detached from the events when the behavior is detached from the component.

The callbacks can be any of the following:

method in this behavior: 'handleClick', equivalent to [$this, 'handleClick']
object method: [$object, 'handleClick']
static method: ['Page', 'handleClick']
anonymous function: function ($event) { ... }

The following is an example:

[
    Model::EVENT_BEFORE_VALIDATE => 'myBeforeValidate',
    Model::EVENT_AFTER_VALIDATE => 'myAfterValidate',
]

Return values

array<string|int, mixed> —

events (array keys) and the corresponding event handler methods (array values).

hasMethod()

Returns a value indicating whether a method is defined.


    public
                    hasMethod(string $name) : bool

The default implementation is a call to php function method_exists(). You may override this method when you implemented the php magic method __call().

Parameters

$name : string: the method name

Return values

bool —

whether the method is defined

hasProperty()

Returns a value indicating whether a property is defined.

the class has a getter or setter method associated with the specified name (in this case, property name is case-insensitive);
the class has a member variable with the specified name (when $checkVars is true);

Parameters

$name : string: the property name
$checkVars : bool = true: whether to treat member variables as properties

Return values

bool —

whether the property is defined
