Question

I am getting this error while simply entering the register page

Undefined index: invite

But when I enter the same page with

url?invite=2000 this error is not shown...

The second line of below code shows the error.

    $mySess = JFactory::getSession();       
    $_SESSION['fromid'] = $_GET['invite'];
    $fromid = $_SESSION['fromid'];

How can i initialize ‘invite’ if its not used in url…

Answer 1

Use the isset function, like so:

$mySess = JFactory::getSession();       
$_SESSION['fromid'] = isset($_GET['invite']) ? $_GET['invite'] : '';
$fromid = $_SESSION['fromid'];
