PHP 클래스 yii\captcha\Captcha

Captcha is used together with CaptchaAction to provide 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 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' => $model, 'attribute' => 'captcha', ]); The following example will use the name property instead: php echo Captcha::widget([ 'name' => 'captcha', ]); You can also use this widget in an [[\yii\widgets\ActiveForm|ActiveForm]] using the [[\yii\widgets\ActiveField::widget()|widget()]] method, for example like this: php field($model, 'captcha')->widget(\yii\captcha\Captcha::classname(), [ configure additional widget properties here ]) ?> 파일 보기 프로젝트 열기: yiisoft/yii2 1 사용 예제들
