Undefined index: memberof

salento9 · May 12, 2011

Hi all,

from my intranet site with ldap fonction for windows AD

i got the error : Undefined index: memberof , this is my code on page:

session_start();

$creatorparts = explode('\\',$_SERVER["REMOTE_USER"]);

$creator = $creatorparts[1];

if($_SESSION['memberof']){

$memberof = $_SESSION['MEMBEROF'];

}else{

$memberof = get_memberships($creator);

$_SESSION['memberof'] = $memberof;

}

Can you help me find what's wrong?

Thanks in advance. :-[

You should be using...

if(isset($_SESSION['memberof'])){

instead of....

if($_SESSION['memberof']){

Be aware that indexes are case sensitive too. Have you set $_SESSION['memberof'] anywhere?

try

if (isset($_SESSION['memberof'])){

Your code is how many people used to code. Only problem is that if your error reporting is set to notice, you get errors, when the variable isn't set. Best to check if it is set, and go from there.

How your code works: if it is set, it's counted as true. If not, it comes back as false with notice.

Done, but now i got a blank page

how can i verify if this variable is defined? i use xampp last version.

print_r($_SESSION) to see what sessions you have set.

No way, always blanc page, here the whole code of header.php file:

<?

/* set the cache limiter to 'private' */
session_cache_limiter('none');
//echo session_cache_limiter();

/* set the cache expire to 3 minutes */
session_cache_expire(3);
//echo session_cache_expire();

session_start();

$creatorparts = explode('\\',$_SERVER["REMOTE_USER"]);
$creator = $creatorparts[1];

if (isset($_SESSION['memberof'])){
  $memberof = $_SESSION['memberof'];
}else{
  $memberof = get_memberships($creator);
  $_SESSION['memberof'] = $memberof;
}

$page = basename($_SERVER["PHP_SELF"]);
$page = substr($page,0,strpos(basename($_SERVER["PHP_SELF"]),'.'));
if(strpos(basename($_SERVER["PHP_SELF"]),'-')){
$page = substr($page,0,strpos(basename($_SERVER["PHP_SELF"]),'-'));
}

$bimAuth = false;
$cpoAuth = false;
$pageAllowed = false;

if($memberof){
  foreach($memberof as $group){
    //echo $group.'*<br>';
    if($group == $bimSecurityGroup){
      $bimAuth = true;
      if(array_search($page,$bimSecurity,1)){
        $pageAllowed = true;    
      }
    }
    if($group == $cpoSecurityGroup){
      $cpoAuth = true;
      if(array_search($page,$cpoSecurity,1)){
        $pageAllowed = true;    
      }
    }
}
}

And you don't receive any errors from this script? Also, what is your error_reporting level set to?

salento9 · May 12, 2011

ok, sorry for trouble, i found the problem for the blank page error after enable on php.ini the ldap extention.

Now the problem is that i receive a page for administrators and not for normal user, it's mean that the check for user rigth in the domain not working.

can you help me?

new code:

<?

/* set the cache limiter to 'private' */
session_cache_limiter('none');
//echo session_cache_limiter();

/* set the cache expire to 3 minutes */
session_cache_expire(3);
//echo session_cache_expire();

session_start();

$creatorparts = explode('\\',$_SERVER["REMOTE_USER"]);
$creator = $creatorparts[1];

if (!empty($_SESSION['memberof'])){
  $memberof = $_SESSION['memberof'];
}else{
  $memberof = get_memberships($creator);
  $_SESSION['memberof'] = $memberof;
}

$page = basename($_SERVER["PHP_SELF"]);
$page = substr($page,0,strpos(basename($_SERVER["PHP_SELF"]),'.'));
if(strpos(basename($_SERVER["PHP_SELF"]),'-')){
$page = substr($page,0,strpos(basename($_SERVER["PHP_SELF"]),'-'));
}

$bimAuth = false;
$cpoAuth = false;
$pageAllowed = false;

if($memberof){
  foreach($memberof as $group){
    //echo $group.'*<br>';
    if($group == $bimSecurityGroup){
      $bimAuth = true;
      if(array_search($page,$bimSecurity,1)){
        $pageAllowed = true;    
      }
    }
    if($group == $cpoSecurityGroup){
      $cpoAuth = true;
      if(array_search($page,$cpoSecurity,1)){
        $pageAllowed = true;    
      }

I don't see anywhere within that code where you actually query any ldap server?
