GuestAccessValidator extends AccessValidator
in package

AccessValidators are responsible for validating a given set of rules.

Rules consist of an array with at leas an rule name and optional further rule settings. If only a rule name is given, the rule is considered global, otherwise it may be restricted to specific actions by providing an action setting e.g.:

// Global myRule
['myRule']

// MyRule restricted to action1 and action2
['myRule' => ['action1', 'action2']]

// Alternative action configuration
['myRule', 'actions' => ['action1', 'action2']]

A Validator has an unique name which is used to detect related rules and can filter out non related rules by means of the filterRelatedRules() function.

AccessValidators have access to a ControllerAccess instance, which holds the ruleset and validation state.

This abstract validator class furthermore provides some helper functions as:

  • isActionRelated(): Checks if a given rule is related to the current action
  • extractActions(): Extracts the action settings from a given rule array
  • getRuleName(): Extracts the rule name from a given rule array

Properties

$actionFilter

public bool $actionFilter = true

determines if this validator is only interested in action related rules or all validator related rules

Methods

__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

Tags
throws
UnknownMethodException

when calling unknown method

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

Tags
throws
UnknownPropertyException

if the property is not defined

throws
InvalidCallException

if the property is write-only

see
__set()
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

Tags
see
https://www.php.net/manual/en/function.isset.php
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

Tags
throws
UnknownPropertyException

if the property is not defined

throws
InvalidCallException

if the property is read-only

see
__get()

__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

Tags
throws
InvalidCallException

if the property is read only.

see
https://www.php.net/manual/en/function.unset.php

canGetProperty()

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

Tags
see
canSetProperty()
Return values
bool —

whether the property can be read

canSetProperty()

Returns a value indicating whether a property can be set.

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

A property is writable if:

  • the class has a 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

bool —

whether the method is defined

hasProperty()

Returns a value indicating whether a property is defined.

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