Returns

delete()source public

delete( string $key )

Delete a cookie value

Optional [Name.], required key $this->Cookie->delete('Name.key);

You must use this method before any output is sent to the browser. Failure to do so will result in header already sent errors.

This method will delete both the top level and 2nd level cookies set. For example assuming that $name = App, deleting User will delete both App[User] and any other cookie values like App[User][email] This is done to clean up cookie storage from before 2.4.3, where cookies were stored inconsistently.

Parameters

string $key

Key of the value to be deleted

Link

destroy()source public

destroy( )

Destroy current cookie

You must use this method before any output is sent to the browser. Failure to do so will result in header already sent errors.

Link

read()source public

read( string $key null )

Read the value of the $_COOKIE[$key];

Optional [Name.], required key $this->Cookie->read(Name.key);

Parameters

string $key optional null

Key of the value to be obtained. If none specified, obtain map key => values

Returns

Link

startup()source public

startup( Controller $controller )

Start CookieComponent for use in the controller

Parameters

Controller $controller

Controller instance.

Overrides

type()source public

type( string $type 'cipher' )

Will allow overriding default encryption method. Use this method in ex: AppController::beforeFilter() before you have read or written any cookies.

Parameters

string $type optional 'cipher'

Encryption method

write()source public

write( string|array $key , mixed $value null , boolean $encrypt true , integer|string $expires null )

Write a value to the $_COOKIE[$key];

string|array $key

Key for the value

mixed $value optional null

Value

boolean $encrypt optional true

Returns

beforeRedirect()source public

beforeRedirect( Controller $controller , string|array $url , integer $status null , boolean $exit true )

Called before Controller::redirect(). Allows you to replace the URL that will be redirected to with a new URL. The return of this method can either be an array or a string.

If the return is an array and contains a 'url' key. You may also supply the following:

• status The status code for the redirect
• exit Whether or not the redirect should exit.

If your response is a string or an array that does not contain a 'url' key it will be used as the new URL to redirect to.

Either the string or URL array that is being redirected to.

integer $status optional null

The status code of the redirect

boolean $exit optional true

Called before the Controller::beforeFilter().

Parameters

Controller $controller

Controller with components to initialize

Link

shutdown()source public

Link

_mergeVars()source protected

_mergeVars( array $properties , string $class , boolean $normalize true )

Merges this objects $property with the property in $class' definition. This classes value for the property will be merged on top of $class'

This provides some of the DRY magic CakePHP provides. If you want to shut it off, redefine this method as an empty function.

Parameters

array $properties

The name of the properties to merge.

string $class

The class to merge the property with.

boolean $normalize optional true

Set to true to run the properties through Hash::normalize() before merging.

Parameters

array $properties optional array()

An associative array containing properties and corresponding values.

_stop()source protected

_stop( integer|string $status 0 )

Stop execution of the current script. Wraps exit() making testing easier.

Parameters

integer|string $status optional 0

see http://php.net/exit for values

dispatchMethod()source public

dispatchMethod( string $method , array $params array() )

Calls a method on this object with the given parameters. Provides an OO wrapper for call_user_func_array

string $method

Name of the method to call

array $params optional array()

Parameter list to use when calling $method

Returns

log()source public

log( string $msg , integer $type LOG_ERR , null|string|array $scope null )

Parameters

string $msg

Log message

integer $type optional LOG_ERR

Error type constant. Defined in app/Config/core.php.

null|string|array $scope optional null

The scope(s) a log message is being created in. See CakeLog::config() for more information on logging scopes.

Returns

requestAction()source 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 $extra optional 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

Boolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.

toString()source public

toString( )

CakeObject-to-string conversion. Each class can override this method as necessary.

Returns
