__callsource 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\Network\Exception\InternalErrorException
If missing the flash message.

__constructsource 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()

setsource 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

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

__debugInfosource public

__debugInfo( )

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

Returns

array

__getsource 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.

implementedEventssource 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
array

Implementation of

Cake\Event\EventListenerInterface::implementedEvents()

initializesource 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.

_configDeletesource protected

_configDelete( string $key )

Delete a single config key

Parameters

string $key

Key to delete.

Throws

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

_configReadsource protected

_configRead( string|null $key )

Read a config variable

Parameters

string|null $key

Key to read.

Returns

mixed
mixed

_configWritesource protected

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

Write a config variable

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

configsource public

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

Usage

Reading the whole config:

$this->config();

Reading a specific value:

$this->config('key');

Reading a nested value:

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

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']);

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.

configShallowsource 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->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']);

Parameters

string|array $key

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

mixed|null $value optional null

The value to set.

Returns

mixed
$this The object itself.

logsource public

log( mixed $msg , integer|string $level LogLevel::ERROR , string|array $context [] )

Parameters

mixed $msg

Log message.

integer|string $level optional LogLevel::ERROR

Error level.

string|array $context optional []

Additional log data relevant to this message.

Returns

boolean
Success of log write.

error( string $message , array $options [] )
