array<string, mixed>__get()
Lazy loads helpers.
public
__get(string $name) : Helper|null|void
Parameters
- $name : string
-
Name of the property being accessed.
Return values
Helper|null|void —Helper instance if helper with provided name exists
addClass()
Adds the given class to the element options
public
addClass(array<string, mixed> $options, string $class[, string $key = 'class' ]) : array<string, mixed>
Parameters
- $options : array<string, mixed>
-
Array options/attributes to add a class to
- $class : string
-
The class name being added.
- $key : string = 'class'
-
the key to use for class. Defaults to
'class'
.
Return values
array<string, mixed> —Array of options with $key set.
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
$thisgetConfig()
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.
Tags
Return values
mixed —Configuration data at the named key
getView()
Get the view instance this helper is bound to.
public
getView() : View
Return values
View —The bound view instance.
hexToRgb()
Converts hex colors to rgb.
public
hexToRgb(string $hexCode) : int
Parameters
- $hexCode : string
-
The hex code of the color. This detects the '#' char.
Return values
int —The RGB code.
implementedEvents()
Get the View callbacks this helper is interested in.
public
implementedEvents() : array<string, mixed>
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.
Return values
array<string, 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

-
The configuration settings provided to this helper.
rgbToHlls()
Gets the hue, lightness, luminosity, and saturation of the color.
public
rgbToHlls(int $RGB) : Hlls

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']);

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