Why am I not able to access the obj name field in script 2? thanks in advance, --script1--- <?php include("TestClass.php"); session_start(); session_register('obj');

session_register() et al are going the way of the dino. just use $_SESSION directly, just remember to call session_start() before you try to use $_SESSION

ob_start(); $obj = new TestClass(); $obj->setName('MyName');

$obj->display();        // outputs 'MyName'

header("Location: http://localhost/~lr/webProj/photoAlbum2/sessionReceiveObj.php"); // re-direct to script2 ob_flush(); ?> ---script 2---- <?php include("TestClass.php"); session_start(); $newObj = $HTTP_SESSION_VARS['obj'];

$newObj->display();       // no output, meaning no data?

$newObj->setName('Michael');

$newObj->display();      // outputs 'Michael' using obj methods

It might be worth noting that if you are using php4 remember to pass your object by reference when setting/retrieving from the session.
