YIi 设置 ajax 验证

开启 ajax 验证

view 层

<?php $form = $this->beginWidget('CActiveForm', array(
    'id'=>'user-form',
    'enableAjaxValidation'=>true,
    'enableClientValidation'=>true,
    'focus'=>array($model,'firstName'),
)); ?>

然后在控制器里面

public function actionCreate()
{
    $model=new User;
    $this->performAjaxValidation($model);
    if(isset($_POST['User']))
    {
        $model->attributes=$_POST['User'];
        if($model->save())
            $this->redirect('index');
    }
    $this->render('create',array('model'=>$model));
}

protected function performAjaxValidation($model)
{
    if(isset($_POST['ajax']) && $_POST['ajax']==='user-form')
    {
        echo CActiveForm::validate($model);
        Yii::app()->end();
    }
}
