Class yii\widgets\InputWidget

继承yii\widgets\InputWidget » yii\base\Widget » yii\base\Component » yii\base\BaseObject
实现yii\base\Configurable, yii\base\ViewContextInterface
子类yii\captcha\Captcha, yii\widgets\MaskedInput
可用版本自2.0
源码 https://github.com/yiichina/yii2/blob/api/framework/widgets/InputWidget.php

InputWidget is the base class for widgets that collect user inputs.

An input widget can be associated with a data $model and an $attribute, or a $name and a $value. If the former, the name and the value will be generated automatically (subclasses may call renderInputHtml() to follow this behavior).

Classes extending from this widget can be used in an ActiveForm using the widget() method, for example like this:

<?= $form->field($model, 'from_date')->widget('WidgetClassName', [
    // configure additional widget properties here
]) ?>

For more details and usage information on InputWidget, see the guide article on forms.
