/** |

* Captcha renders a CAPTCHA image and an input field that takes user-entered verification code. |
||||
* |
||||
* Captcha is used together with [[CaptchaAction]] to provide [CAPTCHA](http://en.wikipedia.org/wiki/Captcha) - a way |
||||
* of preventing website spamming. |
||||
* |
||||
* The image element rendered by Captcha will display a CAPTCHA image generated by |
||||
* an action whose route is specified by [[captchaAction]]. This action must be an instance of [[CaptchaAction]]. |
||||
* |
||||
* When the user clicks on the CAPTCHA image, it will cause the CAPTCHA image |
||||
* to be refreshed with a new CAPTCHA. |
||||
* |
||||
* You may use [[\yii\captcha\CaptchaValidator]] to validate the user input matches |
||||
* the current CAPTCHA verification code. |
||||
* |
||||
* The following example shows how to use this widget with a model attribute: |
||||
* |
||||
* ```php |
||||
* echo Captcha::widget([ |
||||
* 'model' => $model, |
||||
* 'attribute' => 'captcha', |
||||
* ]); |
||||
* ``` |
||||
* |
||||
* The following example will use the name property instead: |
||||
* |
||||
* ```php |
||||
* echo Captcha::widget([ |
||||
* 'name' => 'captcha', |
||||
* ]); |
||||
* ``` |
||||
* |
||||
* You can also use this widget in an [[\yii\widgets\ActiveForm|ActiveForm]] using the [[\yii\widgets\ActiveField::widget()|widget()]] |
||||
* method, for example like this: |
||||
* |
||||
* ```php |
||||
* <?= $form->field($model, 'captcha')->widget(\yii\captcha\Captcha::class, [ |
||||
* // configure additional widget properties here |
||||
* ]) ?> |
||||
* ``` |
