Class yii\web\ViewAction

Inheritance	yii\web\ViewAction » yii\base\Action » yii\base\Component » yii\base\Object
Implements	yii\base\Configurable
Available since version	2.0
Source Code	https://github.com/yiisoft/yii2/blob/master/framework/web/ViewAction.php

ViewAction represents an action that displays a view according to a user-specified parameter.

By default, the view being displayed is specified via the view GET parameter. The name of the GET parameter can be customized via $viewParam.

Users specify a view in the format of path/to/view, which translates to the view name ViewPrefix/path/to/view where ViewPrefix is given by $viewPrefix. The view will then be rendered by the render() method of the currently active controller.

Note that the user-specified view name must start with a word character and can only contain word characters, forward slashes, dots and dashes.

Property Details

$defaultView public property

The name of the default view when yii\web\ViewAction::$viewParam GET parameter is not provided by user. Defaults to 'index'. This should be in the format of 'path/to/view', similar to that given in the GET parameter.

See also yii\web\ViewAction::$viewPrefix.

public string $defaultView = 'index'

$layout public property

The name of the layout to be applied to the requested view. This will be assigned to yii\base\Controller::$layout before the view is rendered. Defaults to null, meaning the controller's layout will be used. If false, no layout will be applied.

public mixed $layout = null

$viewParam public property

The name of the GET parameter that contains the requested view name.

public string $viewParam = 'view'

$viewPrefix public property

A string to be prefixed to the user-specified view name to form a complete view name. For example, if a user requests for tutorial/chap1, the corresponding view name will be pages/tutorial/chap1, assuming the prefix is pages. The actual view file is determined by yii\base\View::findViewFile().

See also yii\base\View::findViewFile().

public string $viewPrefix = 'pages'
