afterRun() public method (available since version 2.0.11)

This method is invoked right after a widget is executed.

The method will trigger the EVENT_AFTER_RUN event. The return value of the method will be used as the widget return value.

If you override this method, your code should look like the following:

public function afterRun($result)
{
    $result = parent::afterRun($result);
    // your custom code here
    return $result;
}

public mixed afterRun ( $result )
$result	mixed	The widget return result.
return	mixed	The processed widget result.

beforeRun() public method (available since version 2.0.11)

This method is invoked right before the widget is executed.

The method will trigger the EVENT_BEFORE_RUN event. The return value of the method will determine whether the widget should continue to run.

When overriding this method, make sure you call the parent implementation like the following:

public function beforeRun()
{
    if (!parent::beforeRun()) {
        return false;
    }

    // your custom code here

    return true; // or false to not run the widget
}

public boolean beforeRun ( )
return	boolean	Whether the widget should continue to be executed.

begin() public static method

Begins a widget.

This method creates an instance of the calling class. It will apply the configuration to the created instance. A matching end() call should be called later. As some widgets may use output buffering, the end() call should be made in the same view to avoid breaking the nesting of output buffers.

See also end().

public static static begin ( $config = [] )
$config	array	Name-value pairs that will be used to initialize the object properties
return	static	The newly created widget instance

end() public static method

Ends a widget.

Note that the rendering result of the widget is directly echoed out.

See also begin().

public static static end ( )
return	static	The widget instance that is ended.
throws	yii\base\InvalidCallException	if begin() and end() calls are not properly nested

getId() public method

Returns the ID of the widget.

public string getId ( $autoGenerate = true )
$autoGenerate	boolean	Whether to generate an ID if it is not set previously
return	string	ID of the widget.

getView() public method

Returns the view object that can be used to render views or view files.

The render() and renderFile() methods will use this view object to implement the actual view rendering. If not set, it will default to the "view" application component.

public yii\web\View getView ( )
return	yii\web\View	The view object that can be used to render views or view files.

getViewPath() public method

Returns the directory containing the view files for this widget.

The default implementation returns the 'views' subdirectory under the directory containing the widget class file.

public string getViewPath ( )
return	string	The directory containing the view files for this widget.

init() public method

Initializes the object.

This method is called at the end of the constructor. The default implementation will trigger an EVENT_INIT event.

public void init ( )

render() public method

Renders a view.

The view to be rendered can be specified in one of the following formats:

• path alias (e.g. "@app/views/site/index");
• absolute path within application (e.g. "//site/index"): the view name starts with double slashes. The actual view file will be looked for under the view path of the application.
• absolute path within module (e.g. "/site/index"): the view name starts with a single slash. The actual view file will be looked for under the view path of the currently active module.
• relative path (e.g. "index"): the actual view file will be looked for under $viewPath.

If the view name does not contain a file extension, it will use the default one .php.

public string render ( $view, $params = [] )
$view	string	The view name.
$params	array	The parameters (name-value pairs) that should be made available in the view.
return	string	The rendering result.
throws	yii\base\InvalidParamException	if the view file does not exist.

renderFile() public method

Renders a view file.

public string renderFile ( $file, $params = [] )
$file	string	The view file to be rendered. This can be either a file path or a path alias.
$params	array	The parameters (name-value pairs) that should be made available in the view.
return	string	The rendering result.
throws	yii\base\InvalidParamException	if the view file does not exist.

run() public method

Executes the widget.

public string run ( )
return	string	The result of widget execution to be outputted.

setId() public method

Sets the ID of the widget.

public void setId ( $value )
$value	string	Id of the widget.

setView() public method

Sets the view object to be used by this widget.

public void setView ( $view )
$view	yii\base\View	The view object that can be used to render views or view files.

widget() public static method

Creates a widget instance and runs it.

The widget rendering result is returned by this method.

public static string widget ( $config = [] )
$config	array	Name-value pairs that will be used to initialize the object properties
return	string	The rendering result of the widget.
throws	Exception
