beforeRender( Cake\Event\Event $event )
beforeRender callback.
Cake\Event\Event
$event
Cake\Controller\Controller::beforeRender()
initialize( )
Initialization hook method.
Cake\Controller\Controller::initialize()
__construct( Cake\Http\ServerRequest $request null , Cake\Network\Response $response null , string|null $name null , Cake\Event\EventManager|null $eventManager null , Cake\Controller\ComponentRegistry|null $components null )
Constructor.
Sets a number of properties based on conventions if they are empty. To override the conventions CakePHP uses you can define properties in your class declaration.
Cake\Http\ServerRequest
$request
optional null Request object for this controller. Can be null for testing, but expect that features that use the request parameters will not work.
$response
optional null $name
optional null Cake\Event\EventManager
|null $eventManager
optional null Cake\Controller\ComponentRegistry
|null $components
optional null __get( string $name )
Magic accessor for model autoloading.
$name
__set( string $name , mixed $value )
Magic setter for removed properties.
$name
$value
_loadComponents( )
Loads the defined components using the Component factory.
_mergeControllerVars( )
Merge components, helpers vars from parent classes.
_viewPath( )
Get the viewPath based on controller name and request prefix.
afterFilter( Cake\Event\Event $event )
Called after the controller action is run and rendered.
Cake\Event\Event
$event
beforeFilter( Cake\Event\Event $event )
Called before the controller action. You can use this method to configure and customize components or perform logic that needs to happen before each controller action.
Cake\Event\Event
$event
beforeRedirect( Cake\Event\Event $event , string|array $url , Cake\Network\Response $response )
The beforeRedirect method is invoked when the controller's redirect method is called but before any further action.
If the event is stopped the controller will not continue on to redirect the request. The $url and $status variables have same meaning as for the controller's method. You can set the event result to response instance or modify the redirect location using controller's response instance.
Cake\Event\Event
$event
$url
A string or array-based URL pointing to another location within the app, or an absolute URL
$response
components( Cake\Controller\ComponentRegistry|null $components null )
Get the component registry for this controller.
If called with the first parameter, it will be set as the controller $this->_components property
Cake\Controller\ComponentRegistry
|null $components
optional null Cake\Controller\ComponentRegistry
implementedEvents( )
Returns a list of all events that will fire in the controller during its lifecycle. You can override this function to add your own listener callbacks
Cake\Event\EventListenerInterface::implementedEvents()
invokeAction( )
Dispatches the controller action. Checks that the action exists and isn't private.
Cake\Controller\Exception\MissingActionException
isAction( string $action )
Method to check that an action is accessible from a URL.
Override this method to change which controller methods can be reached. The default implementation disallows access to all methods defined on Cake\Controller\Controller, and allows all public methods on all subclasses of this class.
$action
loadComponent( string $name , array $config [] )
Add a component to the controller's registry.
This method will also set the component to a property. For example:
$this->loadComponent('Acl.Acl');
Will result in a Toolbar
property being set.
$name
$config
optional [] Cake\Controller\Component
paginate( Cake\ORM\Table|string|Cake\ORM\Query|null $object null , array $settings [] )
Handles pagination of records in Table objects.
Will load the referenced Table object, and have the PaginatorComponent paginate the query using the request date and settings defined in $this->paginate
.
This method will also make the PaginatorHelper available in the view.
Cake\ORM\Table
|string|Cake\ORM\Query
|null $object
optional null Table to paginate (e.g: Table instance, 'TableName' or a Query object)
$settings
optional [] Cake\ORM\ResultSet
redirect( string|array $url , integer $status 302 )
Redirects to given $url, after turning off $this->autoRender.
$url
A string or array-based URL pointing to another location within the app, or an absolute URL
$status

Internally redirects one action to another. Does not perform another HTTP request unlike Controller::redirect()
Examples:
setAction('another_action'); setAction('action_with_parameters', $parameter1);
$action
The new action to be 'redirected' to. Any other parameters passed to this method will be passed as parameters to the new action.
$args
setRequest( Cake\Http\ServerRequest $request )
Sets the request objects and configures a number of controller properties based on the contents of the request. Controller acts as a proxy for certain View variables which must also be updated here. The properties that get set are:
Cake\Http\ServerRequest
$request
shutdownProcess( )
Perform the various shutdown processes for this controller. Fire the Components and Controller callbacks in the correct order.
shutdown
callback.afterFilter
method.startupProcess( )
Perform the startup process for this controller. Fire the Components and Controller callbacks in the correct order.
initialize
callbackbeforeFilter
.startup
methods.dispatchEvent( string $name , array|null $data null , object|null $subject null )

$subject
optional null The object that this event applies to ($this by default).
Cake\Event\Event
eventManager( Cake\Event\EventManager $eventManager null )
Returns the Cake\Event\EventManager manager instance for this object.
You can use this instance to register any new listeners or callbacks to the object events, or create your own events and trigger them at will.
Cake\Event\EventManager
$eventManager
optional null Cake\Event\EventManager
tableLocator( Cake\ORM\Locator\LocatorInterface $tableLocator null )
Sets the table locator. If no parameters are passed, it will return the currently used locator.
Cake\ORM\Locator\LocatorInterface
$tableLocator
optional null Cake\ORM\Locator\LocatorInterface
log( mixed $msg , integer|string $level LogLevel::ERROR , string|array $context [] )

$current
$parent
$isAssoc
_mergeVars( array $properties , array $options [] )

associative
- A list of properties that should be treated as associative arrays. Properties in this list will be passed through Hash::normalize() before merging.$properties
$options
optional [] _setModelClass( string $name )
Set the modelClass and modelKey properties based on conventions.
If the properties are already set they will not be overwritten
$name
loadModel( string|null $modelClass null , string|null $modelType null )

Set or get the model type to be used by this class
$modelType
optional null Cake\Datasource\ModelAwareTrait
requestAction( string|array $url , array $extra [] )
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()
A basic example getting the return value of the controller action:
$variables = $this->requestAction('/articles/popular');
A basic example of request action to fetch a rendered page without the layout.
$viewHtml = $this->requestAction('/articles/popular', ['return']);
You can also pass the URL as an array:
$vars = $this->requestAction(['controller' => 'articles', 'action' => 'popular']);
You can pass POST, GET, COOKIE and other data into the request using the appropriate keys. Cookies can be passed using the cookies
key. Get parameters can be set with query
and post data can be sent using the post
key.
$vars = $this->requestAction('/articles/popular', [ 'query' => ['page' => 1], 'cookies' => ['remember_me' => 1], ]);
By default actions dispatched with this method will use the global $_SERVER and $_ENV values. If you want to override those values for a request action, you can specify the values:
$vars = $this->requestAction('/articles/popular', [ 'environment' => ['CONTENT_TYPE' => 'application/json'] ]);
By default actions dispatched with this method will use the standard session object. If you want a particular session instance to be used, you need to specify it.
$vars = $this->requestAction('/articles/popular', [ 'session' => new Session($someSessionConfig) ]);
$url
String or array-based url. Unlike other url arrays in CakePHP, this url will not automatically handle passed arguments in the $url parameter.
$extra
optional [] if array includes the key "return" it sets the autoRender to true. Can also be used to submit GET/POST data, and passed arguments.
Boolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.
createView( string|null $viewClass null )
Constructs the view class instance based on the current configuration.
$viewClass
optional null Cake\View\View
Cake\View\Exception\MissingViewException
set( string|array $name , mixed $value null )
Saves a variable or an associative array of variables for use inside a template.
$name
$value
optional null Value in case $name is a string (which then works as the key). Unused if $name is an associative array, otherwise serves as the values to $name's keys.
viewBuilder( )
Get the view builder being used.
Cake\View\ViewBuilder
viewOptions( string|array|null $options null , boolean $merge true )
Get/Set valid view options in the object's _validViewOptions property. The property is created as an empty array if it is not set. If called without any parameters it will return the current list of valid view options. See createView()
.
$options
optional null $merge
optional true Whether to merge with or override existing valid View options. Defaults to true
