我有一个名为“user.php”的模型 我有一些验证规则如下 我现在要创建一个密码重置表单 在那个表格中，我有一个文本框名称电子邮件(用户模型中使用的相同电子邮件) 在密码重置表单中，我想检查此用户是否已注册，如果已注册，则会发送密码重置链接

我不知道如何验证这个电子邮件字段，任何帮助都非常感谢，因为我是 YII 的新手

用户.php

    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('user_type', 'length', 'max'=>5),
                        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 attributeLabels()
    {
        return array(
            'id' => 'ID',
            'email' => 'Email',
            'password' => 'Password',
            'user_type' => 'User Type',
                        'cpassword' => 'Confirm Password'
        );
    }
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($this, array(
            'criteria'=>$criteria,
        ));
    }
        public function beforesave()
        {
            $this->password=md5($this->password);
            return true;
        }

Answer 1

您可以使用以下内容检查提交:

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

如果你真的想使用该模型，你可以设置一个规则，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时验证，特别是电子邮件字段。如果它不验证电子邮件地址是否存在

最后，您可以像这样验证单个模型属性:

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

这是完成整个 Action 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,
        ));
    }       
}
