Re: [PHP] session vs. header

2002-11-06 Thread huge junk mail

I think I have to re-explain the problem completely. I want to use this script in a 
login form. Once, someone is authenticated, then I register variables for indentifying 
him/her through session. After I register those variables I want to redirect him/her 
to a page, which required authenticated users (and it's done by registering variables 
through session). Due to this, I decide to use header: location. Futhermore, I use IE 
5.5, Apache 1.3.26, PHP 4.2.1 [, MySQL 3.23.51] which running on Windows ME. Here is 
the script (register globals is off, due to security and default setting in php.ini).

?php
$user = $_POST['user'];
$user = $_POST['password'];
if (authenticate($user))
{
  session_start();
  $_SESSION['user'] = $user;
  $_SESSION['password'] = $password;
  header('Location: http://www.mysite.com/member.php');
  exit();
}
else
{
  header('Location: http://www.mysite.com/login.php');
  exit();
}
?

When I try this code with an authenticated user, it seemed browser don't redirect to 
the page I specify above. The progress bar looked like searching something then it led 
to an error. I don't know why this could happen.

Am I missing something?

Thank you.

What I've done :
1. Allow the user to login
2. Use the login.php page as its own 'form action'
3. Let the login form decide when to redirect the user to the 'destination'
page.
4. force the destination page (welcome.php) to do additional authentication
checking by comparing the users input to some other piece of information
(session variable, cookie, database info, etc...)

Pseudo code for login page

? php
if $user_input = something ||  $more_user_info=somethingelse {
header ('Location: http://www.mysite.com/welcome.php');
}
?

HTML
what ever the login page looks like
/html

Pseudo code for welcome.php:

? php
if $user_input != something ||  $more_user_info!=somethingelse {
header ('Location: http://www.mysite.com/login.php');
}
?

HTML
what ever the welcome page looks like
/html

I believe the php code gets executed before html code is processed.

You can, and you should not get any errors from PHP. The reason someone 
suggested that this can confuse the browser is as follows:

1. When you initiate a session, PHP tells Apache to send a Set-Cookie 
header (assuming you are using the default session settings).
2. When you manually set a Location header, the HTTP response status 
code changes from 200 OK to 302 Moved Temporarily.

So, at least in the past, some Web browsers would ignore Set-Cookie 
headers that are sent in a response that basically says, Hey, that 
thing you are looking for is over here now. Also, in some scripting 
languages (I believe in PHP as well, but I am not positive), the 
Set-Cookie headers would not even be included when you changed the 
status code like this, so it didn't matter what the browser thought.

I have found that this problem appears to be fading fast, and I have 
recently used this combination without any user complaints (yet).  :-)

What problem are you experiencing?

Chris

What is your exact code? I do this all the time and don't have any trouble
with it.

no, sessions never send location headers, they may send cookies but not
location.
