The code for 'main.php' is supposed to send an email to the logged in user reminding them of their password

However the page does not display the logged in users details in stead it shows the first entry in the user database, see code below

// generate user information form
$user = User:: getById(1);
ob_start();

Any help with calling the user ID for the current session to relace the 'getById(1);' which is useless would be most welcome.

just had a look at the book it seems to contain the right code compared with the downloaded code, but doesint seem to work as no username is displayed in the username field.

$user = User::getById($_SESSION['userId']);


Got it!
No
'session_start();'
was included in the file which is needed

I also wasted time dealing with the same errors: the book code for main.php is more correct than the download version. session_start() is in 401.php which is included in main.php, so you don't have to add it in again, but the line including it was commented out in the download version.
