__call()source public

__call( string $name , array $args )

Magic method for verbose flash methods based on element names.

For example: $this->Flash->success('My message') would use the success.ctp element under src/Template/Element/Flash for rendering the flash message.

If you make consecutive calls to this method, the messages will stack (if they are set with the same flash key)

Note that the parameter element will be always overridden. In order to call a specific element from a plugin, you should set the plugin option in $args.

For example: $this->Flash->warning('My message', ['plugin' => 'PluginName']) would use the warning.ctp element under plugins/PluginName/src/Template/Element/Flash for rendering the flash message.

Parameters

string $name

Element name to use.

array $args

Parameters to pass when calling FlashComponent::set().

Throws

Cake\Http\Exception\InternalErrorException
If missing the flash message.

__construct()source public

__construct( Cake\Controller\ComponentRegistry $registry , array $config = [] )

Constructor

Parameters

Cake\Controller\ComponentRegistry $registry

A ComponentRegistry for this component

array $config optional []

Array of config.

Overrides

Cake\Controller\Component::__construct()

getSession()source protected

getSession( )

Returns current session object from a controller request.

Returns

Cake\Http\Session

set()source public

set( string|Exception $message , array $options = [] )

Used to set a session variable that can be used to output messages in the view. If you make consecutive calls to this method, the messages will stack (if they are set with the same flash key)

In your controller: $this->Flash->set('This has been saved');

Options:

• key The key to set under the session's Flash key
• element The element used to render the flash message. Default to 'default'.
• params An array of variables to make available when using an element
• clear A bool stating if the current stack should be cleared to start a new one
• escape Set to false to allow templates to print out HTML content

Parameters

string|Exception $message

Message to be flashed. If an instance of \Exception the exception message will be used and code will be set in params.

array $options optional []

An array of options

__debugInfo()source public

__debugInfo( )

Returns an array that can be used to describe the internal state of this object.

Returns

array

__get()source public

__get( string $name )

Magic method for lazy loading $components.

Parameters

string $name

Name of component to get.

Returns

mixed
A Component object or null.

getController()source public

getController( )

Get the controller this component is bound to.

Returns

Cake\Controller\Controller
The bound controller.

implementedEvents()source public

implementedEvents( )

Get the Controller callbacks this Component is interested in.

Uses Conventions to map controller events to standard component callback method names. By defining one of the callback methods a component is assumed to be interested in the related event.

Override this method if you need to add non-conventional event listeners. Or if you want components to listen to non-standard events.

Returns

array

Implementation of

Cake\Event\EventListenerInterface::implementedEvents()

initialize()source public

initialize( array $config )

Constructor hook method.

Implement this method to avoid having to overwrite the constructor and call parent.

Parameters

array $config

The configuration settings provided to this component.

_configDelete()source protected

_configDelete( string $key )

Deletes a single config key.

Parameters

string $key

Key to delete.

Throws

Cake\Core\Exception\Exception
if attempting to clobber existing config

_configRead()source protected

_configRead( string|null $key )

Reads a config key.

Parameters

string|null $key

Key to read.

Returns

mixed

_configWrite()source protected

_configWrite( string|array $key , mixed $value , boolean|string $merge = false )

Writes a config key.

Parameters

string|array $key

Key to write to.

mixed $value

Value to write.

boolean|string $merge optional false

True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.

Throws

Cake\Core\Exception\Exception
if attempting to clobber existing config

config()source public deprecated

config( string|array|null $key = null , mixed|null $value = null , boolean $merge = true )

Setting a specific value:

$this->config('key', $value);

Setting a nested value:

$this->config('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->config(['one' => 'value', 'another' => 'value']);

Deprecated

3.4.0 use setConfig()/getConfig() instead.

Parameters

string|array|null $key optional null

The key to get/set, or a complete array of configs.

mixed|null $value optional null

The value to set.

boolean $merge optional true

Whether to recursively merge or overwrite existing config, defaults to true.

Returns

mixed
Config value being read, or the object itself on write operations.

Throws

Cake\Core\Exception\Exception
When trying to set a key that is invalid.

configShallow()source public

configShallow( string|array $key , mixed|null $value = null )

Merge provided config with existing config. Unlike config() which does a recursive merge for nested keys, this method does a simple merge.

Setting a specific value:

$this->configShallow('key', $value);

Setting a nested value:

$this->configShallow('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->configShallow(['one' => 'value', 'another' => 'value']);

mixed|null $value optional null

The value to set.
