yii框架中验证器声明一组内置验证器可以使用短名称引用
1.内置验证器的短名称分别有：
boolean: yii\validators\BooleanValidator
captcha: yii\captcha\CaptchaValidator
compare: yii\validators\CompareValidator
date: yii\validators\DateValidator
default: yii\validators\DefaultValueValidator
double: yii\validators\NumberValidator
each: yii\validators\EachValidator
email: yii\validators\EmailValidator
exist: yii\validators\ExistValidator
file: yii\validators\FileValidator
filter: yii\validators\FilterValidator
image: yii\validators\ImageValidator
in: yii\validators\RangeValidator
integer: yii\validators\NumberValidator
match: yii\validators\RegularExpressionValidator
required: yii\validators\RequiredValidator
safe: yii\validators\SafeValidator
string: yii\validators\StringValidator
trim: yii\validators\FilterValidator
unique: yii\validators\UniqueValidator
url: yii\validators\UrlValidator
ip: yii\validators\IpValidator
2. 下面举个例子
1 public function rules() { 2 return [ 3 [['name', 'password', 'email'], 'required'], 4 ['name', 'unique', 'message'=>'{attribute}已经被占用'], 5 ['name', 'string', 'min'=>3, 'max'=>16, 'message'=>'{attribute}的长度必须在3~16之间'], 6 ['email', 'email', 'message'=>'请输入正确的{attribute}'], 7 ['password', 'string', 'min'=>8, 'max'=>16, 'message'=>'{attribute}的长度必须在8~16之间'], 8 ]; 9 }
最后验证这些规则只需要用model调用validate()方法即可，例子如下：
1 //将user对象保存到mongo数据库中 2 public function saveUser($name, $password, $email) { 3 $user = new User(); 4 $user->name = $name; 5 $user->password = $password; 6 $user->email = $email; 7 //在这里用$user调用yii\validators\Validatotr::validate()进行验证所有的属性 8 if ($user->validate()) { 9 $user->insert(); 10 } else { 11 return $user->errors; 12 } 13 }
