redirecting user

[droidus]

i am trying to redirect a user to a certain page, if the credentials are not right.  if there is no session user, they are kicked out.  if it is set, but to the guest account, they go to the login page with a special error message.  here is my code for it:

 

if (!isset($_SESSION['user']))
{
  		header('Location: portal.php?logintocontinue');
	exit;
}
elseif($_SESSION['user'] == "guest") {
	header('Location: portal.php?invalidLogin');
	exit;
}
else {

}

 

after attempting to run the page, with session user = guest, i get this error message: The page isn't redirecting properly.

 

does it have to do with headers already being sent?

Can't tell from that amount of code.

i am not sure what else to add...

 

before, i just had the

if (!isset($_SESSION['user']))
{
  		header('Location: portal.php?logintocontinue');
	exit;
}

 

and it worked.  when i added the elseif statement/else, it stopped working.

In that case, it's probably working as it's written and going into the empty else{} clause. Did you echo $_SESSION['user'] to verify it's value?

what is the datatype of $_SESSION['user']

 

Your code appears to handle it as a string.  Is it perhaps an object or an array, thus $_SESSION['user']['type'] should be compared?

 

as Pikachu2000 said, little more info would be handy

 

thanks,
