__debugInfo() ¶ public
__debugInfo(): array<string, mixed>Returns an array that can be used to describe the internal state of this object.
Returns
array<string, mixed>__get() ¶ public
__get(string $name): Cake\View\Helper|nullLazy loads helpers.
Parameters
-
string$name Name of the property being accessed.
Returns
Cake\View\Helper|null_configDelete() ¶ protected
_configDelete(string $key): voidDeletes a single config key.
Parameters
-
string$key Key to delete.
Returns
voidThrows
Cake\Core\Exception\CakeExceptionif attempting to clobber existing config
_configRead() ¶ protected
_configRead(string|null $key): mixedReads a config key.
Parameters
-
string|null$key Key to read.
Returns
mixed_configWrite() ¶ protected
_configWrite(array<string, mixed>|string $key, mixed $value, string|bool $merge = false): voidWrites a config key.
Parameters
-
array<string, mixed>|string$key Key to write to.
-
mixed$value Value to write.
-
string|bool$merge optional True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.

'class'.
Returns
array<string, mixed>configShallow() ¶ public
configShallow(array<string, mixed>|string $key, mixed|null $value = null): $thisMerge 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:
$this->configShallow(['one' => 'value', 'another' => 'value']);Parameters
-
array<string, mixed>|string$key The key to set, or a complete array of configs.
-
mixed|null$value optional The value to set.
Returns
$thisget() ¶ public
get(string|null $key = null): mixedGets user data
Parameters
-
string|null$key optional Key of something you want to get from the identity data
Returns
mixedgetConfig() ¶ public
getConfig(string|null $key = null, mixed $default = null): mixedReturns the config.
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:
$this->getConfig('some-key', 'default-value');Parameters
-
string|null$key optional The key to get or null for the whole config.
-
mixed$default optional The return value when the key does not exist.
Returns
mixedgetConfigOrFail() ¶ public
getConfigOrFail(string $key): mixedReturns the config for this specific key.
The config value for this key must exist, it can never be null.
Parameters
-
string$key The key to get.
Returns
mixedThrows
InvalidArgumentExceptiongetId() ¶ public
getId(): array|string|int|nullGets the id of the current logged in identity
Returns
array|string|int|nullgetView() ¶ public
getView(): Cake\View\ViewGet the view instance this helper is bound to.
Returns
Cake\View\ViewimplementedEvents() ¶ public
implementedEvents(): array<string, mixed>Get the View callbacks this helper is interested in.
By defining one of the callback methods a helper 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 helpers to listen to non-standard events.
Returns
array<string, mixed>initialize() ¶ public
initialize(array<string, mixed> $config): voidConstructor hook method.
Implement this method to avoid having to overwrite the constructor and call parent.
Parameters
-
array<string, mixed>$config The configuration settings provided to this helper.
Returns
voidis() ¶ public
is(string|int $id, string $field = 'id'): boolThis check can be used to tell if a record that belongs to some user is the current logged in user and compare other fields as well
If you have more complex requirements on visibility checks based on some kind of permission you should use the Authorization plugin instead:
https://github.com/cakephp/authorization
This method is mostly a convenience method for simple cases and not intended to replace any kind of proper authorization implementation.
Parameters
-
string|int$id Identity id to check against
-
string$field optional Name of the field in the identity data to check against, id by default
Returns
boolsetConfig() ¶ public
setConfig(array<string, mixed>|string $key, mixed|null $value = null, bool $merge = true): $thisSets the config.
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:
$this->setConfig(['one' => 'value', 'another' => 'value']);Parameters
-
array<string, mixed>|string$key The key to set, or a complete array of configs.
-
mixed|null$value optional The value to set.
-
bool$merge optional Whether to recursively merge or overwrite existing config, defaults to true.
Returns
$thisThrows
Cake\Core\Exception\CakeExceptionWhen trying to set a key that is invalid.
