    'enableAjaxValidation' => true,
    'enableClientValidation' => true,
    这两句放上去就报错,这是为什么?
    PHP Parse Error – yii\base\ErrorException
    syntax error, unexpected ''enableAjaxValidation'' (T_CONSTANT_ENCAPSED_STRING), expecting ']'

    'id' => 'form-signup' 后边少逗号

    觉得很赞

    是粘贴直接就能使吗?

    if (Yii::$app->request->isAjax) {

            Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
            return \yii\bootstrap\ActiveForm::validate($model);
        }
    

    <?php $form = ActiveForm::begin([

                'id' => 'form-signup',
                'enableAjaxValidation' => true,
                'enableClientValidation' => true,
            ]); ?>
    

    这两段是用来验证ajax的么?

    enableAjaxValidation是用来控制是否开启 ajax验证的
