Behavior
in package

Application

implements EventListenerInterface uses InstanceConfigTrait

Base class for behaviors.

Behaviors allow you to simulate mixins, and create reusable blocks of application logic, that can be reused across several models. Behaviors also provide a way to hook into model callbacks and augment their behavior.

Mixin methods

Behaviors can provide mixin like features by declaring public methods. These methods will be accessible on the tables the behavior has been added to.

function doSomething($arg1, $arg2) {
  // do something
}

Would be called like $table->doSomething($arg1, $arg2);.

Callback methods

Behaviors can listen to any events fired on a Table. By default, CakePHP provides a number of lifecycle events your behaviors can listen to:

beforeFind(EventInterface $event, Query $query, ArrayObject $options, boolean $primary) Fired before each find operation. By stopping the event and supplying a return value you can bypass the find operation entirely. Any changes done to the $query instance will be retained for the rest of the find. The $primary parameter indicates whether this is the root query, or an associated query.
buildValidator(EventInterface $event, Validator $validator, string $name) Fired when the validator object identified by $name is being built. You can use this callback to add validation rules or add validation providers.
buildRules(EventInterface $event, RulesChecker $rules) Fired when the rules checking object for the table is being built. You can use this callback to add more rules to the set.
beforeRules(EventInterface $event, EntityInterface $entity, ArrayObject $options, $operation) Fired before an entity is validated using by a rules checker. By stopping this event, you can return the final value of the rules checking operation.
afterRules(EventInterface $event, EntityInterface $entity, ArrayObject $options, bool $result, $operation) Fired after the rules have been checked on the entity. By stopping this event, you can return the final value of the rules checking operation.
beforeSave(EventInterface $event, EntityInterface $entity, ArrayObject $options) Fired before each entity is saved. Stopping this event will abort the save operation. When the event is stopped the result of the event will be returned.
afterSave(EventInterface $event, EntityInterface $entity, ArrayObject $options) Fired after an entity is saved.
beforeDelete(EventInterface $event, EntityInterface $entity, ArrayObject $options) Fired before an entity is deleted. By stopping this event you will abort the delete operation.
afterDelete(EventInterface $event, EntityInterface $entity, ArrayObject $options) Fired after an entity has been deleted.

In addition to the core events, behaviors can respond to any event fired from your Table classes including custom application specific ones.

You can set the priority of a behaviors callbacks by using the priority setting when attaching a behavior. This will set the priority for all the callbacks a behavior provides.

Finder methods

Behaviors can provide finder methods that hook into a Table's find() method. Custom finders are a great way to provide preset queries that relate to your behavior. For example a SluggableBehavior could provide a find('slugged') finder. Behavior finders are implemented the same as other finders. Any method starting with find will be setup as a finder. Your finder methods should expect the following arguments:

findSlugged(Query $query, array $options)

Interfaces

EventListenerInterface: Objects implementing this interface should declare the `implementedEvents()` method to notify the event manager what methods should be called when an event is triggered.

Properties

$_config : array<string, mixed>: Runtime config
$_configInitialized : bool: Whether the config property has already been configured with defaults
$_defaultConfig : array<string, mixed>: Default configuration
$_reflectionCache : array<string, array<string|int, mixed>>: Reflection method cache for behaviors.
$_table : Table: Table instance.

Methods

__construct() : mixed: Constructor
configShallow() : $this: Merge provided config with existing config. Unlike `config()` which does a recursive merge for nested keys, this method does a simple merge.
getConfig() : mixed: Returns the config.
getConfigOrFail() : mixed: Returns the config for this specific key.
getTable() : Table: Get the table instance this behavior is bound to.
implementedEvents() : array<string, mixed>: Gets the Model callbacks this behavior is interested in.
implementedFinders() : array<string|int, mixed>: implementedFinders
implementedMethods() : array<string|int, mixed>: implementedMethods
initialize() : void: Constructor hook method.
setConfig() : $this: Sets the config.
table() : Table: Get the table instance this behavior is bound to.
verifyConfig() : void: verifyConfig
_configDelete() : void: Deletes a single config key.
_configRead() : mixed: Reads a config key.
_configWrite() : void: Writes a config key.
_reflectionCache() : array<string|int, mixed>: Gets the methods implemented by this behavior
_resolveMethodAliases() : array<string|int, mixed>: Removes aliased methods that would otherwise be duplicated by userland configuration.

$_config

Runtime config


    protected
        array<string, mixed>
    $_config
     = []

$_configInitialized

Whether the config property has already been configured with defaults


    protected
        bool
    $_configInitialized
     = false

$_defaultConfig

Default configuration


    protected
        array<string, mixed>
    $_defaultConfig
     = []

These are merged with user-provided configuration when the behavior is used.

$_reflectionCache

Reflection method cache for behaviors.


    protected
    static    array<string, array<string|int, mixed>>
    $_reflectionCache
     = []

Stores the reflected method + finder methods per class. This prevents reflecting the same class multiple times in a single process.

$_table

Table instance.


    protected
        Table
    $_table

__construct()

Constructor


    public
                    __construct(Table $table[, array<string, mixed> $config = [] ]) : mixed

Merges config with the default and store in the config property

Parameters

$table : Table: The table this behavior is attached to.
$config : array<string, mixed> = []: The config for this behavior.

configShallow()

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


    public
                    configShallow(array<string, mixed>|string $key[, mixed|null $value = null ]) : $this

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']);

Parameters

$key : array<string, mixed>|string: The key to set, or a complete array of configs.
$value : mixed|null = null: The value to set.

Return values

$this

getConfig()

Returns the config.


    public
                    getConfig([string|null $key = null ][, mixed $default = null ]) : mixed

Usage

Reading the whole config:

$this->getConfig();

Reading a specific value:

$this->getConfig('key');

Reading a nested value:

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

Reading with default value:

$this->getConfig('some-key', 'default-value');

Parameters

$key : string|null = null: The key to get or null for the whole config.
$default : mixed = null: The return value when the key does not exist.

Return values

mixed —

Configuration data at the named key or null if the key does not exist.

getConfigOrFail()

Returns the config for this specific key.


    public
                    getConfigOrFail(string $key) : mixed

The config value for this key must exist, it can never be null.

Parameters

$key : string: The key to get.

Return values

mixed —

Configuration data at the named key

getTable()

Get the table instance this behavior is bound to.


    public
                    getTable() : Table

Use table() instead.

Return values

Table —

The bound table instance.

implementedEvents()

Gets the Model callbacks this behavior is interested in.


    public
                    implementedEvents() : array<string, mixed>

By defining one of the callback methods a behavior 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 your behavior to listen to non-standard events.

Return values

array<string, mixed>

implementedFinders()

implementedFinders


    public
                    implementedFinders() : array<string|int, mixed>

Provides an alias->methodname map of which finders a behavior implements. Example:

 [
   'this' => 'findThis',
   'alias' => 'findMethodName'
 ]

With the above example, a call to $table->find('this') will call $behavior->findThis() and a call to $table->find('alias') will call $behavior->findMethodName()

It is recommended, though not required, to define implementedFinders in the config property of child classes such that it is not necessary to use reflections to derive the available method list. See core behaviors for examples

Return values

array<string|int, mixed>

implementedMethods()

implementedMethods


    public
                    implementedMethods() : array<string|int, mixed>

Provides an alias->methodname map of which methods a behavior implements. Example:

 [
   'method' => 'method',
   'aliasedMethod' => 'somethingElse'
 ]

With the above example, a call to $table->method() will call $behavior->method() and a call to $table->aliasedMethod() will call $behavior->somethingElse()

Return values

array<string|int, mixed>

initialize()

Constructor hook method.


    public
                    initialize(array<string, mixed> $config) : void

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

Parameters

$config : array<string, mixed>: The configuration settings provided to this behavior.

setConfig()

Sets the config.


    public
                    setConfig(array<string, mixed>|string $key[, mixed|null $value = null ][, bool $merge = true ]) : $this

Usage

Setting a specific value:

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

Setting a nested value:

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

Updating multiple config settings at the same time:

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

Parameters

$key : array<string, mixed>|string: The key to set, or a complete array of configs.
$value : mixed|null = null: The value to set.
$merge : bool = true: Whether to recursively merge or overwrite existing config, defaults to true.

Return values

$this

table()

Gets the methods implemented by this behavior


    protected
                    _reflectionCache() : array<string|int, mixed>
