i'm trying to check if a session exist and has a specific value (2) to show a part of the website and if not it should return you to a other page.

So far i got this: 

$_SESSION["deel"] = "2";  //set session deel to 2
$result = array("error" => false, "html" => null);
$result["error"] = false;
$result["html"] = "<h3>Session information:";
$result["html"] .= "<a href='/shop/?,69'>$_SESSION[class2C]</a>";
$result["html"] .= "</h3>";

after that we go to a other page:

if (!isset($_SESSION['deel']) || $_SESSION['deel'] == '2')
{ show the shit }
else 
{ redirect }

However, it doesn't do anything and just shows me "the shit"
what am i doing wrong here?

Thanks in advance.

    How about a session_start() before you use session? – Rizier123 Nov 27 '14 at 16:17
  • this is only a part of the total script and yes the session gets started. in above scripts and this file itself. – Justin Nov 27 '14 at 16:27

    Then why you check if the session['deel'] is NOT set OR it's equal to 2? So if it's not set you show sh*t, but if it is set and equal's to 2 you also show sh*t – Rizier123 Nov 27 '14 at 16:28

Your condition is wrong

if (!isset($_SESSION['deel']) || $_SESSION['deel'] == '2')
    ^                         ^^

Means if the session is not set or if it is set then the value is 2, This will be true even if there is no session. You should do:

if (isset($_SESSION['deel']) && $_SESSION['deel'] == 2)

This can also be derived from your own statement

                      ^       ^          ^
 if (isset($_SESSION['deel']) &&  $_SESSION['deel'] == 2)

  • damnit, im still confusing the !isset and isset.. didnt know what the || did in this case i thought i was something similar to && – Justin Nov 27 '14 at 16:48

  • `!` before something means `NOT` of that. `&&` means `AND`, `||` means `OR`. That post i mentioned explains it all clearly – Hanky Panky Nov 27 '14 at 16:50
