This update works with database mysql
**You must generate the user model with GII**
My login form look like this
```php
<?php
/* @var $this SiteController */
/* @var $model LoginForm */
/* @var $form CActiveForm */
$this->pageTitle=Yii::app()->name . ' - Login';
$this->breadcrumbs=array(
'Login',
);
?>
<h1>Login</h1>
<p>Please fill out the following form with your login credentials:</p>
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'login-form',
'enableClientValidation'=>true,
'clientOptions'=>array(
'validateOnSubmit'=>true,
),
)); ?>
<p class="note">Fields with <span class="required">*</span> are required.</p>
<div class="row">
<?php echo $form->labelEx($model,'email'); ?>
<?php echo $form->textField($model,'email'); ?>
<?php echo $form->error($model,'email'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'password'); ?>
<?php echo $form->passwordField($model,'password'); ?>
<?php echo $form->error($model,'password'); ?>
<p class="hint">
Hint: You may login with <kbd>demo</kbd>/<kbd>demo</kbd> or <kbd>admin</kbd>/<kbd>admin</kbd>.
</p>
</div>
<div class="row rememberMe">
<?php echo $form->checkBox($model,'rememberMe'); ?>
<?php echo $form->label($model,'rememberMe'); ?>
<?php echo $form->error($model,'rememberMe'); ?>
</div>
<div class="row buttons">
<?php echo CHtml::submitButton('Login'); ?>
</div>
<?php $this->endWidget(); ?>
</div><!-- form -->
```
In SiteController.php no more changes ```php /** *
* LoginForm is the data structure for keeping
* user login form data. It is used by the 'login' action of 'SiteController'.
*/
class LoginForm extends CFormModel
{
public $password;
public $rememberMe;
public $email; // Email
private $_identity;
/**
* Declares the validation rules.
* The rules state that username and password are required,
* and password needs to be authenticated.
*/
public function rules()
{
return array(
// username and password are required
array('email, password', 'required'),
// rememberMe needs to be a boolean
array('rememberMe', 'boolean'),
array('email', 'email'),
// password needs to be authenticated
array('password', 'authenticate'),
);
}
/**
* Declares attribute labels.
*/
public function attributeLabels()
{
return array(
'rememberMe'=>'Remember me next time',
);
}
/**
* Authenticates the password.
* This is the 'authenticate' validator as declared in rules().
*/
public function authenticate($attribute,$params)
{
if(!$this->hasErrors())
{
$this->_identity=new UserIdentity($this->email,$this->password);
if(!$this->_identity->authenticate())
$this->addError('password','Incorrect username or password.');
}
}
/**
* Logs in the user using the given username and password in the model.
* @return boolean whether login is successful
*/
public function login()
{
if($this->_identity===null)
{
$this->_identity=new UserIdentity($this->email,$this->password);
$this->_identity->authenticate();
}
if($this->_identity->errorCode===UserIdentity::ERROR_NONE)
{
$duration=$this->rememberMe ? 3600*24*30 : 0; // 30 days
Yii::app()->user->login($this->_identity,$duration);
return true;
}
else
return false;
}
}
```
And then extends CUserIdentity
```php
/**
* UserIdentity represents the data needed to identity a user.
* It contains the authentication method that checks if the provided
* data can identity the user.
*/
class UserIdentity extends CUserIdentity
{
/**
* @var string email
*/
public $email;
const ERROR_EMAIL_INVALID=1;
/**
* @param string $email
* @param string $password
*/
public function __construct($email, $password)
{
parent::__construct($email, $password);
$this->email=$email;
}
/**
* Authenticates a user.
* The example implementation makes sure if the username and password
* are both 'demo'.
* In practical applications, this should be changed to authenticate
* against some persistent user identity storage (e.g. database).
* @return boolean whether authentication succeeds.
*/
public function authenticate()
{
$users=array(
// username => password
'demo@demo.fr'=>'demo',
'admin@admin.fr'=>'admin'
);
if(!isset($users[$this->email]))
$this->errorCode=self::ERROR_EMAIL_INVALID;
elseif($users[$this->email]!==$this->password)
$this->errorCode=self::ERROR_PASSWORD_INVALID;
else
$this->errorCode=self::ERROR_NONE;
return !$this->errorCode;
}
/**
* @return mixed
*/
public function getPassword()
{
return $this->password;
}
/**
* @return mixed
*/
public function getEmail()
{
return $this->email;
}
}
```
*/
public function actionLogin()
{
if (!defined('CRYPT_BLOWFISH')||!CRYPT_BLOWFISH)
throw new CHttpException(500,"This application requires that PHP was compiled with Blowfish support for crypt().");
$model=new LoginForm;
// if it is ajax validation request
if(isset($_POST['ajax']) && $_POST['ajax']==='login-form')
{
echo CActiveForm::validate($model);
Yii::app()->end();
}
// collect user input data
if(isset($_POST['LoginForm']))
{
$model->attributes=$_POST['LoginForm'];
// validate user input and redirect to the previous page if valid
if($model->validate() && $model->login())
$this->redirect(Yii::app()->user->returnUrl);
}
// display the login form
$this->render('login',array('model'=>$model));
}
```
The LoginForm in models directory
```php
<?php
/**
* LoginForm class.
* LoginForm is the data structure for keeping
* user login form data. It is used by the 'login' action of 'SiteController'.
*/
class LoginForm extends CFormModel
{
public $username;
public $email;
public $password;
public $rememberMe;
private $_identity;
/**
* Declares the validation rules.
* The rules state that username and password are required,
* and password needs to be authenticated.
*/
public function rules()
{
return array(
// username and password are required
array('email, password', 'required'),
array('email', 'email'),
// rememberMe needs to be a boolean
array('rememberMe', 'boolean'),
// password needs to be authenticated
array('password', 'authenticate'),
);
}
/**
* Declares attribute labels.
*/
public function attributeLabels()
{
return array(
'rememberMe'=>'Remember me next time',
);
}
/**
* Authenticates the password.
* This is the 'authenticate' validator as declared in rules().
*/
public function authenticate($attribute,$params)
{
if(!$this->hasErrors())
{
$this->_identity=new UserIdentity($this->username, $this->password, $this->email);
if(!$this->_identity->authenticate())
$this->addError('password','Incorrect username or password.');
}
}
/**
* Logs in the user using the given username and password in the model.
* @return boolean whether login is successful
*/
public function login()
{
if($this->_identity===null)
{
$this->_identity=new UserIdentity($this->username, $this->password, $this->email);
$this->_identity->authenticate();
}
if($this->_identity->errorCode===UserIdentity::ERROR_NONE)
{
$duration=$this->rememberMe ? 3600*24*30 : 0; // 30 days
Yii::app()->user->login($this->_identity,$duration);
return true;
}
else
return false;
}
}
```
And finally the UserIdentity in components directory
```php
<?php
/**
* UserIdentity represents the data needed to identity a user.
* It contains the authentication method that checks if the provided
* data can identity the user.
*/
class UserIdentity extends CUserIdentity
{
/**
* @var string email
*/
public $email;
/**
* @var int id
*/
private $_id;
const ERROR_EMAIL_INVALID=1;
public function __construct($username, $password, $email)
{
parent::__construct($username, $password);
$this->email=$email;
}
/**
* Authenticates a user.
* The example implementation makes sure if the email and password
* are both 'demo'.
* In practical applications, this should be changed to authenticate
* against some persistent user identity storage (e.g. database).
* @return boolean whether authentication succeeds.
*/
public function authenticate()
{
$model=User::model()->findByAttributes(array('email'=>$this->email));
if($model===null)
$this->errorCode=self::ERROR_EMAIL_INVALID;
elseif(!crypt($this->password, $model->password))
$this->errorCode=self::ERROR_PASSWORD_INVALID;
else
$this->_id=$model->id;
$this->username=$model->username;
$this->errorCode=self::ERROR_NONE;
return !$this->errorCode;
}
/**
* @return integer the ID of the user record
*/
public function getId()
{
return $this->_id;
}
}
