In this wiki I will show how could be store last login date & time in database. First we need a field LastLoginTime (Type must be datetime). this field store a user login detalis (like - Date & Time).

In your components

Create a file called WebUser.php into components directory. In which needs to define the WebUser class, which should be an extension of the Yii CWebUser class. Within that class, we will defined a method afterLogin(), eg. -

class WebUser extends CWebUser {
	
	public function afterLogin()
	{
		if (parent::beforeLogout()) {
			$user = User::model()->findByPk(Yii::app()->user->id);
			$user->LastLoginTime=date('Y-m-d H:i:s');
			$user->saveAttributes(array('LastLoginTime'));
			return true;
		} else {
			return false;
		}
	}	
 }

In Your config main.php

Need to set WebUser class in user array -

'class'=>'WebUser'

eg. -

// application components
   'components'=>array(
       'user'=>array(
	      'class'=>'WebUser',  //Adding WebUser class
	      'allowAutoLogin'=>true,
	      'autoRenewCookie' => true,
               'loginUrl' => array('site/login'),
	),
   ),

In your UserIdentity.php

Set the last login time in varible lastLoginTime in authenticate() function after successfully authentication.

public function authenticate() {
	
		$attribute = strpos($this->username, '@') ? 'email' : 'username';
		
		$user = User::model()->find(array('condition' => $attribute . '=:loginname', 'params' =>
			array(':loginname' => $this->username)));
			
		
		
		if ($user === null) {
		         
			$this->errorCode = self::ERROR_USERNAME_INVALID;
		} 
		
	    else if ($user->Password!=md5($this->password)) {
		
		 $this->errorCode = self::ERROR_PASSWORD_INVALID;
		}
		
		else {
			
			$this->_id = $user->Id;
			$this->_LastLoginTime = $user->LastLoginTime;
			$this->username = $user->Email;

			$this->setState('lastLoginTime', $user->LastLoginTime); //set the last login time in varible lastLoginTime from the database. 

			$this->errorCode = self::ERROR_NONE;
			
		}
	return !$this->errorCode;
}

Now you can easily print or get your last login time anywhere, eg. -

echo Yii::app()->user->lastLoginTime;

It's show your last time login details (date & time). see in your database, your LastLoginTime table field having different date & time. becuase it's your Current login details (date & time). so if you want to show also your current login details, you can get directory from LastLoginTime fields.

Try this, working great in yii 1.1
