Php operation class based on session and cookie User Logon status, sessioncookie

1. User Login status operation class UserLogin

 

<?phpfinal class UserLogin {    public function __construct() {            }    public static function getUserInfo() {        if (isset($_COOKIE["user_id"])&&$_COOKIE["user_id"]&&(trim($_COOKIE["user_id"])!="")) {            if (isset($_SESSION["USER_INFO"]))                return $_SESSION["USER_INFO"];            $dao = new UserDao();            $user = $dao->find($_COOKIE["user_id"]);            if ($user) {                $_SESSION["USER_INFO"] = $user;                setcookie("docloud_sid", session_id(), time() + 36000);                setcookie("user_id", $_COOKIE["user_id"], time() + 36000);                                if (array_key_exists("selected_prj_id", $_COOKIE))                    setcookie("selected_prj_id", $_COOKIE["selected_prj_id"], time() + 36000);                                if (array_key_exists("selected_class_id", $_COOKIE))                    setcookie("selected_class_id", $_COOKIE["selected_class_id"], time() + 36000);                                if (array_key_exists("selected_image_id", $_COOKIE))                    setcookie("selected_image_id", $_COOKIE["selected_image_id"], time() + 36000);                                if (array_key_exists("test_image_ids", $_COOKIE))                    setcookie("test_image_ids", $_COOKIE["test_image_ids"], time() + 36000);                                if (array_key_exists("upload_image_ids", $_COOKIE))                    setcookie("upload_image_ids", $_COOKIE["upload_image_ids"], time() + 36000);                return $user;            }        }        self::clearCookie();        return null;    }    public static function setUserInfo($userInfo) {        $_SESSION["USER_INFO"] = $userInfo;        setcookie("docloud_sid", session_id(), time() + 36000);        setcookie("user_id", $userInfo->getId(), time() + 36000);    }    public static function isLogin() {        if (self::getUserInfo()) {            return true;        }        return false;    }    public static function delUserInfo() {        self::clearCookie();        session_destroy();    }        private static function clearCookie() {        setcookie("docloud_sid", "", time() - 36000);        setcookie("user_id", "", time() - 36000);        setcookie("selected_prj_id", "", time() - 36000);        setcookie("selected_class_id", "", time() - 36000);        setcookie("selected_image_id", "", time() - 36000);        setcookie("test_image_ids", "", time() - 36000);        setcookie("upload_image_ids", "", time() - 36000);    }}?>

 

2. the user enters the user name and password for relevant determination.

 

<? Phprequire_once 'init. php '; // if logged in, logoutif (UserLogin: isLogin () & $ _ COOKIE ["user_id"] = 1) {UserLogin: delUserInfo ();} else if (UserLogin: isLogin () {Utils: redirect ('Welcome ') ;}$ username = null; $ password = null; $ msg = ""; if (isset ($ _ POST ['username']) & isset ($ _ POST ['Password']) {$ username = addslashes (trim (stripslashes ($ _ POST ['username']); $ password = addslashes (trim (stripslashes ($ _ POST ['Password']); // validate $ errors = LoginValidator: validate ($ username, $ password); if (empty ($ errors )) {// save $ dao = new UserDao (); $ user = $ dao-> findByName ($ username); $ last_login_ip = Utils: getIpAddress (); $ user-> setLastLoginIp ($ last_login_ip); $ now = new DateTime (); $ user-> setLastLoginTime ($ now); $ dao-> save ($ user); UserLogin:: setUserInfo ($ user); Flash: addFlash ('logon successful! '); Utils: redirect ('Welcome');} foreach ($ errors as $ e) {$ msg. = $ e-> getMessage (). "<br>" ;}}?>
