Trait InstanceConfigTrait
A trait for reading and writing instance config
Implementing objects are expected to declare a $_defaultConfig property.
Property Summary
-
$_config protected
arrayRuntime config
-
$_configInitialized protected
boolWhether the config property has already been configured with defaults
Method Summary
-
_configDelete() protected
Deletes a single config key.
-
_configRead() protected
Reads a config key.
-
_configWrite() protected
Writes a config key.
-
config() public deprecated
Gets/Sets the config.
-
configShallow() public
Merge provided config with existing config. Unlike
config()which does a recursive merge for nested keys, this method does a simple merge. -
getConfig() public
Returns the config.
-
setConfig() public
Sets the config.
Method Detail
_configDelete() ¶ protected
_configDelete(string $key): voidDeletes a single config key.
Parameters
-
string$key Key to delete.
Returns
voidThrows
Cake\Core\Exception\Exceptionif 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(string|array $key, mixed $value, bool|string $merge = false): voidWrites a config key.
Parameters
-
string|array$key Key to write to.
-
mixed$value Value to write.
-
bool|string$merge optional True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.
Returns
voidThrows
Cake\Core\Exception\Exceptionif attempting to clobber existing config
config() ¶ public
config(string|array|null $key = null, mixed|null $value = null, bool $merge = true): mixedGets/Sets the config.
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 The key to get/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
mixedConfig value being read, or the object itself on write operations.
Throws
Cake\Core\Exception\ExceptionWhen trying to set a key that is invalid.
configShallow() ¶ public
configShallow(string|array $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:
$this->configShallow(['one' => 'value', 'another' => 'value']);Parameters
-
string|array$key The key to set, or a complete array of configs.
-
mixed|null$value optional The value to set.
Returns
$thisgetConfig() ¶ public
getConfig(string|null $key = null): mixedReturns the config.
Usage
Reading the whole config:
$this->getConfig();Reading a specific value:
$this->getConfig('key');Reading a nested value:
$this->getConfig('some.nested.key');Parameters
-
string|null$key optional The key to get or null for the whole config.
Returns
mixedConfig value being read.
setConfig() ¶ public
setConfig(string|array $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:
$this->setConfig(['one' => 'value', 'another' => 'value']);Parameters
-
string|array$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\ExceptionWhen trying to set a key that is invalid.
