Problem using $_SERVER['LOGON_USER']

pgrantuk

Hi All

I am trying to use the user id of the logged in user as part of an if statement

If I run some example code as

<?php
$user = $_SERVER['LOGON_USER'];
Print "$user"
?>

The page will display my user id ie TestDomain\TestUser

however, If I try to put in an if statement before it like this...

<?php
$user = $_SERVER['LOGON_USER'];
if ( $user == "TestDomain\TestUser" )
Print "$user"
?>

Nothing is displayed, can anyone tell me what i'm doing wrong?

Thanks

hmm... I cannot remember the details offhand, but your post title mentions $SERVER['AUTH_USER'], but your code uses $SERVER['LOGON_USER'].

Ah sorry, i've amended it now

from what I can tell the LOGON_USER and AUTH_USER do the same thing and i've tried both but to no avail

Beyond what laserlight had pointed out (which is a good point).. when working with IIS / IE Authentication (keep in mind only IE will automatically pass the variable to the server)

try:

print_r("<pre>%s</pre>",print_r($_SERVER,true));

and take a look at all system variables which are not being played with by your browser, it will basically display "pain text".

Be sure that you are trapping the correct string.

Please note that you have to backslashes (\). In PHP, with the "double quote" (") when you enter:

<?php
$user = $_SERVER['LOGON_USER'];
if ( $user == "TestDomain\\TestUser" ) 
Print "$user"
?>

PHP see's it as TestDomain\TestUser

This is the correct convention (with AD Domain\User) however I just wanted to ensure that your output and condition statements are checking for the same thing.

Thanks for taking a look

I've tried ..

<?
print_r("<pre>%s</pre>",print_r($_SERVER,true));
?>

But nothing is displayed on the page?

I used \ in the code as when I run

$user = $_SERVER['LOGON_USER'];
Print "$user

That what the page displays, i've also tried it using \ but still get the same problems

pragantuk:

Have you tried:

<?php 
print_r("<pre>&#37;s</pre>",print_r($_SERVER,true));
?>

The <?php without the short-tags.

If nothing is being displayed that seems kind of funny.

Also, to simulate \ in PHP, you would use "\\" as "\" = "\". The backslash is an escape character used with many things (\t for tab, \n for newline, etc etc).

I would try to get that $_SERVER dump (the first thing I recommended) working so you can see ALL Server variables available to PHP.
