PHP Session!

Hi,

I am trying to get the value of a session veriable and if the variable contains a certain word it will show an error message, else just continue as normal.

 

if (isset($_POST['selectroom']))
{$_SESSION['room'] = $_POST['selectroom'];}
if (!isset($_SESSION['room']))
$room = "RoomNameA";
else
$room = $_SESSION['room'];

 

Please Advise,

- Stuart

missing the curlies from the else there, try to keep to one standard, don't mix and match - bad practise.

 

use isset() then !empty() this proves as it's there and has state...

 

Ideally, you need to post more of the code so we can see what else is going on in there.

Personally I'd structure it like this:

 

if (!empty($_POST['selectroom']))
{
    $room = htmlentities($_POST['selectroom']);
    $_SESSION['room'] = $room;
}
elseif (isset($_SESSION['selectroom']))
{
    $room = $_SESSION['selectroom'];
}
else
{
    $room = "RoomNameA";
}

 

Perhaps drop the htmlentities call if you escape the value somewhere else.
