Tested browsers: firefox 3.6.16 chromium 10.0.648.133 IE 8 The content of index.php. <?php include_once 'Webshop.php'; // class Webshop include_once 'InputChecker.php'; // static class InputChecke include_once 'LayoutMaker.php'; // static class LayoutMaker session_start (); // check for the first visit if (!isset ($_SESSION ['webshop'])) $_SESSION ['webshop'] = new Webshop (); // handels all input from $_POST include_once 'postChecker.php'; if (InputChecker::getPageAction ($_GET ['p']) == PageAction::LOGOUT) $_SESSION ['webshop'] -> setRole (Role::VISITOR); if (InputChecker::isInputCorrect ($_GET ['c'], $_GET ['s'], $_GET ['b'], $_GET ['p'], $_SESSION ['webshop'] -> getCategories (), $_SESSION ['webshop'] -> getBrands ())) { echo LayoutMaker::getTop (); echo LayoutMaker::getPageWithPointers ($_GET ['c'], $_GET ['s'], $_GET ['b'], $_GET ['a'], $_GET ['p'], $_SESSION ['webshop'] -> getRole (), $_SESSION ['webshop'] -> getCategories (), $_SESSION ['webshop'] -> getBrands ()); echo LayoutMaker::getBottom ($_SESSION ['webshop'] -> getRole ()); } else { echo LayoutMaker::getTop (); echo LayoutMaker::getPageWithoutPointers ($_SESSION ['webshop'] -> getCategories ()); echo LayoutMaker::getBottom (); } ?> Content of postChecker.php: <?php require_once '/someWhere/loginInfoSite.php'; // contains username and password if (isset ($_POST ['username']) && isset ($_POST ['password']) && $_POST ['username'] == $username && $_POST ['password'] == $password) $_SESSION ['webshop'] -> setRole (Role::ADMIN); ?>

Hi, My php application works abnormal. The used code to mange session is: include_once "classesFiles"; session_start (); // check for the first visit if (!isset ($_SESSION ['anObject'])) $_SESSION ['anObject'] = new Object (); $username = "xxx"; $password = "yyy"; if (isset ($_POST ['username']) && isset ($_POST ['password']) && $_POST ['username'] == $username && $_POST ['password'] == $password) $_SESSION ['anObject'] -> setRole (Role::ADMIN); if (InputChecker::getPageAction ($_GET ['p']) == PageAction::LOGOUT) $_SESSION ['anObject'] -> setRole (Role::VISITOR); ... I tested the code as follow: 1- go to the site 2- log in 3- make a new tab in the same browser 4- go to the site from the new tab (I am already logged in) 5- log out from the new tab 6- go to the first tab 7- refresh the tab. I am still logged in (I find this behavior abnormal) The second test: 1- go to the site 2- log in 3- make a new tab in the same browser 4- go to the site from the new tab (I am already logged in) 5- go to the first tab 6- log out 7- go to the second tab 8- refresh the tab. I am logged out (I find this normal) The order of tabs from which I log out is important. Does anyone have an idea why the first test dose not work normal? Thanks,

At the first line, the characters &, " and ' have to convert to entities, don't they?

[quote author=HuggieBear link=topic=113440.msg460993#msg460993 date=1162372581] The function in your class is called aadbar (notice the two 'a') and you call is using addbar (notice the two 'd'). Regards Huggie [/quote] Thanks
