You can set your model validations as below
您可以如下设置模型验证
public function rules()
{
// NOTE: you should only define rules for those attributes that
// will receive user inputs.
return array(
//First parameter is your field name of table which has email value
array('email', 'email','message'=>"The email isn't correct"),
array('email', 'unique','message'=>'Email already exists!'),
);
}

You can create your custom validation method to fulfill your requirement.
您可以创建自定义验证方法来满足您的要求。
Create a function in model class:
在模型类中创建一个函数：
public function uniqueEmail($attribute, $params)
{
// Set $emailExist variable true or false by using your custom query on checking in database table if email exist or not.
// You can user $this->{$attribute} to get attribute value.
$emailExist = true;
if($emailExist)
$this->addError('email','Email already exists');
}
User this validation method in rules:
在规则中使用此验证方法：
array('email', 'uniqueEmail','message'=>'Email already exists!'),

Custom validation, short and sweet code. try this it's working fine -
自定义验证，简短而甜蜜的代码。试试这个它工作正常 -
public function rules(){
return array(
array('email, first_name, last_name, password, repeat_password', 'required'),
array('email', 'email','message'=>"The email isn't correct"),
array('email', 'uniqueEmail'),
);
}
write this custom function in the same model -
在同一个模型中编写这个自定义函数 -
public function uniqueEmail($attribute, $params){
if($user = User::model()->exists('email=:email',array('email'=>$this->email)))
$this->addError($attribute, 'Email already exists!');
}

For Yii2 I used the following in a model called Register which will use the User Class.
对于 Yii2，我在名为 Register 的模型中使用了以下内容，该模型将使用用户类。
public function rules()
{
return [
['Email', 'filter', 'filter' => 'trim'],
['Email', 'required'],
['Email', 'email'],
['Email', 'unique', 'targetClass' => '\common\models\User', 'message' => 'This email address has already been taken.'],
];
}
You need to use targetClass and put the Namepsace for the Class User
您需要使用 targetClass 并为 Class User 放置 Namepsace

You can easily find either email is already present in your db or not by defining the rule.
通过定义规则，您可以轻松地找到电子邮件是否已经存在于您的数据库中。
Here is the rule.
这是规则。
array('xxx', 'unique', 'className' => 'SomeClass', 'attributeName' => 'SomeAttribute'),
Example.
例子。
public function rules() {
return array(
...
array('email', 'unique', 'className' => 'User', 'attributeName' => 'email', 'message'=>'This Email is already in use'),
...
);
}
Here i want to put validation on Email, which is unique, my model class name is User, attributeName is the field name of the table i.e. email and if email is already present in your table then display message.
在这里，我想对电子邮件进行验证，这是唯一的，我的模型类名称是 User，attributeName 是表的字段名称，即电子邮件，如果电子邮件已经存在于您的表中，则显示消息。
If it gives error then you may change your table and make unique the email field.
如果出现错误，则您可以更改表格并使电子邮件字段唯一。
ALTER TABLE user ADD UNIQUE (email)
ALTER TABLE 用户添加唯一（电子邮件）
Then check.
然后检查。
other email validations are in below. which i think complete set of email validation.
其他电子邮件验证如下。我认为这是一套完整的电子邮件验证。
public function rules() {
return array(
...
array('email', 'required'),
array('email', 'length', 'max'=>200),
array('email', 'email', 'message'=>'Email is not valid'),
array('email', 'unique', 'className' => 'User', 'attributeName' => 'email', 'message'=>'This Email is already in use'),
...
); }
That's it. Thanks
就是这样。谢谢
