Global variabiles ????

ovisopa

Hello ppl,

I'm wondering if somebody knows why every script I try and it uses $PHP_AUTH_USER and all the stuff for login scripts it's not working 🙁 .

Below i copied a part of a login script, this part must popup a window in witch I must insert the user and the pass ??

    if(!isset($PHP_AUTH_USER)) {
        Header("WWW-Authenticate: Basic realm=\"Title of the restricted area?\"");
        Header("HTTP/1.0 401 Unauthorized");
        exit;
    }

$PHP_AUTH_USER is a globar variabile, like $GET and others ... is somewhere in the php config or apache config file a line about this variabiles, and maibe it is comented and I should uncoment the line???

Any help is apreciated

10x in advance

see ya all

You could try $_SERVER['PHP_AUTH_USER'] or set register_globals = on in your php.ini file.

In file php.ini it's ok, that line was already set to "on" but I see the problem is when this header is send

header("WWW-Authenticate: Basic realm=\"Autentificare HTTP cu PHP\"");
header("HTTP/1.0 401 Unauthorized");

the error I receive is ths :

Internal Server Error

Hi,
try to use ' ' instead of " " and not escape any char...
like this:

header('WWW-Authenticate: Basic realm="Autentificare HTTP cu PHP"');
header('HTTP/1.0 401 Unauthorized');

see you

I tried and it still not working,here is the script

<?php
$PHP_AUTH_USER = "ovis";
$PHP_AUTH_PW = "pass";
 if(!isset($PHP_AUTH_USER)) {
    auth();
//se trimit headerele pentru autentificare
    echo "Autentificare oprita! Ati apasat Cancel";
//daca se apasa Cancel
    exit;
  }
  else if(isset($PHP_AUTH_USER)){

require("db.inc.php");

$query="select * from_users where user='$PHP_AUTH_USER' and pass='$PHP_AUTH_PW'"; //interogarea
$result=mysql_query($query);
if($result) {
	$num_rows=mysql_num_rows($result); // cate rezultate am gasit
}
else $num_rows=0;
    if($num_rows) {
    echo "Salut $PHP_AUTH_USER!<BR>";
    echo "Ai introdus parola <b>$PHP_AUTH_PW</b> !";
}
else auth();
  }

function auth() {
header('WWW-Authenticate: Basic realm="Autentificare HTTP cu PHP"'); 
header('HTTP/1.0 401 Unauthorized'); 
}
?>

I set the php_auth_user in the top of the code, if I modify the pass in to pas it should popup the login window, I'm wright ??

Nop!😃

The variables are initializzed by Authenticate function..

Look this:

<? if (!isset($_SERVER['PHP_AUTH_USER'])) {
    header('WWW-Authenticate: Basic realm="Stats on VT"');
    header('HTTP/1.0 401 Unauthorized');
    echo 'aborted';
    exit;
  } else {
  	if ($_SERVER['PHP_AUTH_USER']!='stat' &&
  		$_SERVER['PHP_AUTH_PW']!='vt')
  	{?>
		<HTML>
		<HEAD>
		<LINK rel="stylesheet" type="text/css" href="stile.css">
				</HEAD>
		<BODY>
		<h1> forbidden </h1>
		</BODY></HTML>
  	<? exit;
  	}
  }
echo 'allrigth';

I tried on local and it's the same error, but on the web it's working.

In the log files I found this :

I fogot to mention that I use NuSphere as my apache server, is this the problem ??????
