根据经验，您永远不应该相信从最终用户那里收到的数据，并且应该在很好地使用这些数据之前对其进行验证。
给定一个model模型，用户输入填充后，您可以通过调用yii\base\Model::validate()方法。该方法将返回一个布尔值，指示验证是否成功。否则，您可能会从?yii\base\Model::$errors?获取错误信息。举个例子，
$model = new \app\models\ContactForm();
// 接收到的参数
$model->load(\Yii::$app->request->post());
// 其等效于以下内容
// $model->attributes = \Yii::$app->request->post('ContactForm');
if ($model->validate()) {
// 所有验证通过
} else {
// 验证失败：$errors是一个包含错误消息的数组
$errors = $model->errors;
}
public function rules()
{
return [
// the name, email, subject and body attributes are required
[['name', 'email', 'subject', 'body'], 'required'],
// the email attribute should be a valid email address
['email', 'email'],
];
}?有时候你需要做特殊验证对于未绑定到任何模型的值。
如果您只需要执行一种类型的验证(例如验证电子邮件地址)，您可以调用验证()方法，如下所示:
$email = 'test@example.com';
$validator = new yii\validators\EmailValidator();
if ($validator->validate($email, $error)) {
echo 'Email is valid.';
} else {
echo $error;

?内联验证器是根据模型方法或匿名函数定义的。方法/函数的签名是:
use yii\base\Model;
class MyForm extends Model
{
public $country;
public $token;
public function rules()
{
return [
// an inline validator defined as the model method validateCountry()
['country', 'validateCountry'],
// an inline validator defined as an anonymous function
['token', function ($attribute, $params, $validator) {
if (!ctype_alnum($this->$attribute)) {
$this->addError($attribute, 'The token must contain letters or digits.');
}
}],
];
}
public function validateCountry($attribute, $params, $validator)
{
if (!in_array($this->$attribute, ['USA', 'Indonesia'])) {
$this->addError($attribute, 'The country must be either "USA" or "Indonesia".');
}
}
