我不知道如何撤销这个电子邮件领域，任何帮助都非常令人满意，因为我在YII时是新的

user.php的

    class Users extends CActiveRecord
{
public $cpassword;
    public static function model($className=__CLASS__)
    {
        return parent::model($className);
    }
public function tableName()
    {
        return 'users';
    }
public function rules()
    {
        // NOTE: you should only define rules for those attributes that
        // will receive user inputs.
        return array(
            array('email, password, user_type , cpassword','required'),
            array('email', 'length', 'max'=>200),
                        array('email', 'unique'),
                        array('email', 'email'),
            array('password', 'length', 'max'=>300),
                        array('cpassword', 'length', 'max'=>300),

                        array('cpassword', 'compare', 'compareAttribute' => 'password'),

            // The following rule is used by search().
            // Please remove those attributes that should not be searched.
            array('id, email, password, user_type ', 'safe', 'on'=>'search'),
        );
    }
public function relations()

return array(
        );
    }

public function search()
    {
        // Warning: Please modify the following code to remove attributes that
        // should not be searched.

        $criteria=new CDbCriteria;

        $criteria->compare('id',$this->id);
        $criteria->compare('email',$this->email,true);
        $criteria->compare('password',$this->password,true);
        $criteria->compare('user_type',$this->user_type,true);

        return new CActiveDataProvider($this, array(

        ));
    }
        public function beforesave()

            $this->password=md5($this->password);
            return true;

Answer 1

您可以通过以下内容查看提交内容：

$user = User::model()->find("email = '".trim($model->email)."'");
if (!empty($user)){
     // users exists
} else {
    // user does not exist
}

如果您真的想使用该模型，您可以设置一个规则，其中电子邮件必须是唯一的，如下所示：

array('email', 'unique', 'message' => 'Email already in use'),

然后，您可以检查模型是否在提交上验证，特别是电子邮件字段。如果它不验证电子邮件地址存在

最后，您可以验证单个模型属性，如下所示：

if($model->validate(array('attribute_name')) 
     // valid
}

以下是执行完整操作的一种方法（不是最好的方法，但最容易理解！）

public function actionResetpassword(){
        $model = new User;
        if(isset($_POST['User'])){
            $model->attributes = $_POST['User']; // this is the form as completed by the user
            $user = User::model()->find("email = '".trim($model->email)."'");
            if (!empty($user)){
                // send user their new email
                $this->render("passwordreset"); // user exists, render confirmtion page
            } else {
                // user does not exist, render form and pass $error_message variable with messasge 
                $this->render("resetpassword",array(
                    "model"         =>  $model,
                    "error_message" =>  "No such user found!",
                ));
            }
    } else {
        // this will be rendered if the user has not submitted the form yet
        $this->render("resetpassword",array(
            "model" =>  $model,
        ));
    }       
}

Answer 2

public function rules() {

    $action = Yii::app()->controller->action->id;
    if($action == 'login'){
        return array(array('username,password', 'required'), array('password', 'length', 'min'=>6, 'max'=>12), array('rememberMe', 'boolean'), array('password', 'authenticate'), array('id, jsid, email, username, password, status', 'safe', 'on'=>'search'));
    }else{
        return array( array('oldpassword,password1,password2', 'required'), array('password1,password2, oldpassword', 'length', 'min'=>6, 'max'=>12),array('password1', 'compare', 'compareAttribute'=>'password2'), array('id, jsid, email, username, password, status', 'safe', 'on'=>'search'),);    
    }
}
