在protected\config\main.php配置数组中存在该数组，转到component索引。在该user数组中，具有关联索引值'allowAutoLogin'，必须具有布尔值true
因此，它应该如下所示

'components' => array(
    'user' => array(
        // enable cookie-based authentication
        'allowAutoLogin' => true,
    ),
 ...

你必须使用下面的属性沿着下面给出的登录方法，你可以很容易地实现记住我。

class LoginForm extends CFormModel
{
    public $username;
    public $password;
    public $rememberMe;

    private $_identity;

在Login模型类中，login方法应该如下所示

public function login()
{
    if($this->_identity===null)
    {
        $this->_identity=new UserIdentity($this->username, $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;
}

这是记忆函数的核心代码

Yii::app()->user->login($this->_identity,$duration);

给你
