Method Detail
_getUsersource protected
_getUser( )
Similar to AuthComponent::user() except if the session user cannot be found, connected authentication objects will have their getUser() methods called. This lets stateless authentication methods function correctly.
Returns
booleantrue if a user can be found, false if one cannot.
_isAllowedsource protected
_isAllowed( Controller $controller )
Checks whether current action is accessible without authentication.
Parameters
-
Controller$controller - A reference to the instantiating controller object
Returns
booleanTrue if action is accessible without authentication else false
_isLoginActionsource protected
_isLoginAction( Controller $controller )
Normalizes $loginAction and checks if current request URL is same as login action.
Parameters
-
Controller$controller - A reference to the controller object.
Returns
booleanTrue if current action is login action else false.
_setDefaultssource protected
_setDefaults( )
Attempts to introspect the correct values for object properties.
Returns
booleanTrue
_unauthenticatedsource protected
_unauthenticated( Controller $controller )
Handles unauthenticated access attempt. First the unathenticated() method of the last authenticator in the chain will be called. The authenticator can handle sending response or redirection as appropriate and return true to indicate no furthur action is necessary. If authenticator returns null this method redirects user to login action. If it's an ajax request and $ajaxLogin is specified that element is rendered else a 403 http status code is returned.
Parameters
-
Controller$controller - A reference to the controller object.
Returns
booleanTrue if current action is login action else false.
_unauthorizedsource protected
_unauthorized( Controller $controller )
Handle unauthorized access attempt
Parameters
-
Controller$controller - A reference to the controller object
Returns
booleanReturns false
Throws
ForbiddenExceptionForbiddenException
See
AuthComponent::$unauthorizedRedirectallowsource public

$this->Auth->allow(array('edit', 'add')); or $this->Auth->allow('edit', 'add'); or $this->Auth->allow(); to allow all actions

http://book.cakephp.org/2.0/en/core-libraries/components/authentication.html#making-actions-require-authorizationflashsource public
flash( string $message )
Set a flash message. Uses the Session component, and values from AuthComponent::$flash.
Parameters
- string
$message - The message to set.
identifysource public
identify( CakeRequest $request , CakeResponse $response )
Use the configured authentication adapters, and attempt to identify the user by credentials contained in $request.
Parameters
-
CakeRequest$request - The request that contains authentication data.
-
CakeResponse$response - The response
Returns
arrayUser record data, or false, if the user could not be identified.
initializesource public
initialize( Controller $controller )
Initializes AuthComponent for use in the controller.
Parameters
-
Controller$controller - A reference to the instantiating controller object
Overrides
Component::initialize() isAuthorizedsource public
isAuthorized( array $user null , CakeRequest $request null )
Check if the provided user is authorized for the request.
Uses the configured Authorization adapters to check whether or not a user is authorized. Each adapter will be checked in sequence, if any of them return true, then the user will be authorized for the request.
Parameters
- array
$useroptional null - The user to check the authorization of. If empty the user in the session will be used.
-
CakeRequest$requestoptional null - The request to authenticate for. If empty, the current request will be used.
Returns
booleanTrue if $user is authorized, otherwise false
loggedInsource public
loggedIn( )
Check whether or not the current user has data in the session, and is considered logged in.
Deprecated
3.0.0 Since 2.5. Use AuthComponent::user() directly.Returns
booleantrue if the user is logged in, false otherwise
loginsource public
login( array $user null )
Log a user in.
If a $user is provided that data will be stored as the logged in user. If $user is empty or not specified, the request will be used to identify a user. If the identification was successful, the user record is written to the session key specified in AuthComponent::$sessionKey. Logging in will also change the session id in order to help mitigate session replays.
Parameters
- array
$useroptional null - Either an array of user data, or null to identify a user using the current request.
Returns
booleanTrue on login success, false on failure

logout( )
Log a user out.
Returns the logout action to redirect to. Triggers the logout() method of all the authenticate objects, so they can perform custom logout logic. AuthComponent will remove the session data, so there is no need to do that in an authentication object. Logging out will also renew the session id. This helps mitigate issues with session replays.
Returns
stringAuthComponent::$logoutRedirect

mapActions( array $map array() )
Maps action names to CRUD operations.
Used for controller-based authentication. Make sure to configure the authorize property before calling this method. As it delegates $map to all the attached authorize objects.

password( string $password )

stringHashed password
redirectsource public
redirect( string|array $url null )
Backwards compatible alias for AuthComponent::redirectUrl().

Returns
stringRedirect URL
redirectUrlsource public
redirectUrl( string|array $url null )
Get the URL a user should be redirected to upon login.
Pass a URL in to set the destination a user should be redirected to upon logging in.
If no parameter is passed, gets the authentication redirect URL. The URL returned is as per following rules:
- Returns the normalized URL from session Auth.redirect value if it is present and for the same domain the current app is running on. - If there is no session value and there is a $loginRedirect, the $loginRedirect value is returned. - If there is no session and no $loginRedirect, / is returned.
Parameters
- string|array
$urloptional null - Optional URL to write as the login redirect URL.
Returns
stringRedirect URL
startupsource public
startup( Controller $controller )
Main execution method. Handles redirecting of invalid users, and processing of login form data.
Parameters
-
Controller$controller - A reference to the instantiating controller object
Returns
booleanbool
Overrides
Component::startup() usersource public static
user( string $key null )
Get the current user.
Will prefer the static user cache over sessions. The static user cache is primarily used for stateless authentication. For stateful authentication, cookies + sessions will be used.
Parameters
- string
$keyoptional null - field to retrieve. Leave null to get entire User record
Returns
mixed|nullUser record. or null if no user is logged in.

requestActionsource public
requestAction( string|array $url , array $extra array() )
Calls a controller's method from any location. Can be used to connect controllers together or tie plugins into a main application. requestAction can be used to return rendered views or fetch the return value from controller actions.
Under the hood this method uses Router::reverse() to convert the $url parameter into a string URL. You should use URL formats that are compatible with Router::reverse()
Passing POST and GET data
POST and GET data can be simulated in requestAction. Use $extra['url'] for GET data. The $extra['data'] parameter allows POST data simulation.
Parameters
- string|array
$url - String or array-based URL. Unlike other URL arrays in CakePHP, this URL will not automatically handle passed and named arguments in the $url parameter.
- array
$extraoptional array() - if array includes the key "return" it sets the AutoRender to true. Can also be used to submit GET/POST data, and named/passed arguments.
Returns
mixedBoolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.
toStringsource public
toString( )
Object-to-string conversion. Each class can override this method as necessary.
Returns
stringThe name of this class
