AssetBundle represents a collection of asset files, such as CSS, JS, images.
Each asset bundle has a unique name that globally identifies it among all asset bundles used in an application. The name is the fully qualified class name of the class representing it.
An asset bundle can depend on other asset bundles. When registering an asset bundle with a view, all its dependent asset bundles will be automatically registered.
For more details and usage information on AssetBundle, see the guide article on assets.

Property Details
The Web-accessible directory that contains the asset files in this bundle.
If $sourcePath is set, this property will be overwritten by yii\web\AssetManager when it publishes the asset files from $sourcePath.
You can use either a directory or an alias of the directory.
The base URL for the relative asset files listed in $js and $css.
If $sourcePath is set, this property will be overwritten by yii\web\AssetManager when it publishes the asset files from $sourcePath.
You can use either a URL or an alias of the URL.
List of CSS files that this bundle contains. Each CSS file can be specified in one of the three formats as explained in $js.
Note that only a forward slash "/" should be used as directory separator.
The options that will be passed to yii\web\View::registerCssFile() when registering the CSS files in this bundle.
List of bundle class names that this bundle depends on.
For example:
public $depends = [
'yii\web\YiiAsset',
'yii\bootstrap\BootstrapAsset',
];
List of JavaScript files that this bundle contains. Each JavaScript file can be specified in one of the following formats:
- an absolute URL representing an external asset. For example,
https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js
or//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js
. - a relative path representing a local asset (e.g.
js/main.js
). The actual file path of a local asset can be determined by prefixing $basePath to the relative path, and the actual URL of the asset can be determined by prefixing $baseUrl to the relative path. - an array, with the first entry being the URL or relative path as described before, and a list of key => value pairs that will be used to overwrite $jsOptions settings for this entry. This functionality is available since version 2.0.7.
Note that only a forward slash "/" should be used as directory separator.
The options that will be passed to yii\web\View::registerJsFile() when registering the JS files in this bundle.
The options to be passed to yii\web\AssetManager::publish() when the asset bundle is being published. This property is used only when $sourcePath is set.
The directory that contains the source asset files for this asset bundle. A source asset file is a file that is part of your source code repository of your Web application.
You must set this property if the directory containing the source asset files is not Web accessible. By setting this property, yii\web\AssetManager will publish the source asset files to a Web-accessible directory automatically when the asset bundle is registered on a page.
If you do not set this property, it means the source asset files are located under $basePath.
You can use either a directory or an alias of the directory.
See also $publishOptions.
Method Details
Defined in: yii\base\BaseObject::__call()
Calls the named method which is not a class method.
Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.
public mixed __call ( $name, $params ) | ||
$name | string |
The method name |
$params | array |
Method parameters |
return | mixed |
The method return value |
---|---|---|

{
throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
Defined in: yii\base\BaseObject::__construct()
Constructor.
The default implementation does two things:
- Initializes the object with the given configuration
$config
. - Call init().
If this method is overridden in a child class, it is recommended that
- the last parameter of the constructor is a configuration array, like
$config
here. - call the parent implementation at the end of the constructor.
public void __construct ( $config = [] ) | ||
$config | array |
Name-value pairs that will be used to initialize the object properties |
public function __construct($config = [])
{
if (!empty($config)) {
Yii::configure($this, $config);
}
$this->init();
}
Defined in: yii\base\BaseObject::__get()
Returns the value of an object property.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $value = $object->property;
.
See also __set().
public mixed __get ( $name ) | ||
$name | string |
The property name |
return | mixed |
The property value |
---|---|---|
throws | yii\base\UnknownPropertyException |
if the property is not defined |
throws | yii\base\InvalidCallException |

public function __get($name)
{
$getter = 'get' . $name;
if (method_exists($this, $getter)) {
return $this->$getter();
} elseif (method_exists($this, 'set' . $name)) {
throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
}
throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
}
Defined in: yii\base\BaseObject::__isset()
Checks if a property is set, i.e. defined and not null.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing isset($object->property)
.
Note that if the property is not defined, false will be returned.
public boolean __isset ( $name ) | ||
$name | string |
The property name or the event name |
return | boolean |
Whether the named property is set (not null). |
---|

if (method_exists($this, $getter)) {
return $this->$getter() !== null;
}
return false;
}
Defined in: yii\base\BaseObject::__set()
Sets value of an object property.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $object->property = $value;
.
See also __get().
public void __set ( $name, $value ) | ||
$name | string |
The property name or the event name |

} else {
throw new UnknownPropertyException('Setting unknown property: ' . get_class($this) . '::' . $name);
}
}
Defined in: yii\base\BaseObject::__unset()
Sets an object property to null.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing unset($object->property)
.
Note that if the property is not defined, this method will do nothing. If the property is read-only, it will throw an exception.
public void __unset ( $name ) | ||
$name | string |
The property name |
throws | yii\base\InvalidCallException |

$checkVars
is true);
See also canGetProperty().
