ajax - Yii2 ajax 和客户端验证不起作用

Question

Ajax 验证未触发，需要帮助找出我的代码有什么问题，斗争花了足够长的时间让我在这里寻求帮助，所以请帮忙。有一些带注释的代码，在尝试使其工作时使用。收到 500 内部服务器错误:

{"name":"Exception","message":"Attribute name must contain word characters only."

用户 Controller

public function actionRegister()
{        
    $model = new Users();
    if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {
        $model->scenario = 'ajax';
        Yii::$app->response->format = Response::FORMAT_JSON;
        Yii::error($model);
        $model->validate();
        return ActiveForm::validate($model);
        //both ways not working the way it should
        //return $model->validate();
    }     
    if ($model->load(Yii::$app->request->post())) {
        if ($user = $model->register()) {                
            if (Yii::$app->getUser()->login($user)) {
                return $this->goHome();
            }
        }
    }
    return $this->render('register', [

Answer 1

嘿，你的代码很好，但你的错误是你为单个表单提供了两个 id，一个是 form-signsup 和 ajax。尝试只使用一个...:)

<?php $form = ActiveForm::begin(['id' => 'form-signsup',

                    'enableAjaxValidation' => false,
                    'enableClientValidation' => true,
                    //'id' => 'ajax'
                    ]); ?>
