Class Controller

Application controller class for organization of business logic. Provides basic functionality, such as rendering views inside layouts, automatic model availability, redirection, callbacks, and more.

Controllers should provide a number of 'action' methods. These are public methods on the controller that are not prefixed with a '_' and not part of Controller. Each action serves as an endpoint for performing a specific action on a resource or collection of resources. For example: adding or editing a new object, or listing a set of objects.

You can access request parameters, using $this->request. The request object contains all the POST, GET and FILES that were part of the request.

After performing the required actions, controllers are responsible for creating a response. This usually takes the form of a generated View, or possibly a redirection to another controller action. In either case $this->response allows you to manipulate all aspects of the response.

Controllers are created by Dispatcher based on request parameters and routing. By default controllers and actions use conventional names. For example /posts/index maps to PostsController::index(). You can re-map URLs using Router::connect().

Methods inherited from CakeObject

_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'

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.

_set()source protected

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

Returns

mixed

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

boolean
Success of log write

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

mixed

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


toString()source public
