PHP session is not working

I am working with wamp2.0 - PHP 5.3, apache 2.2.11 but my sessions are not storing data.

I have a page that accepts a parameter, which (simplified version) I wanna store in a session, so when I come to

http://www.example.com/home.php?sessid=db_session_id

The script looks like:

session_start();

$sessid = @$_GET['sessid'];
if ($sessid) {
  $_SESSION['sessid'] = $sessid;
}
var_dump($_SESSION);

and outputs:

array(1) { [0]=> string(13) "db_session_id" }

which is fine, but then, when I go to link (without the sessid parameter) the $_SESSION array is empty. I've event tried to comment the $_SESSION['sessid'] = $sessid; line before going to the page without the parameter, but still it didin't work.

I've checked the session_id() output and the session id remains the same.

EDIT:

The sessions are deleted by an iframe. I don't know why, but when commented, the sessions work fine. Thing is, the iframe has to stay there (which of course is bad, but I can't do anything about it). Well...do you know about any workarounds to get the sessions working with an iframe?

Solution

  • A frame can access the session only if it's relative to the same domain. For example:

    <? 
$_SESSION["foo"]="foo"; 
?><html> 
 <body> 
  <iframe src ="test.php" width="200" height="200"></iframe> 
 </body> 
</html> 
<? 
print_r($_SESSION); 
?>

    Should work outside and inside the iframe. If your still having problems try:

     <?php  session_start();

    $sessid = $_GET['sessid'];
    if (isset($sessid) && $sessid != "" && $sessid != NULL) {
      $_SESSION['sessid'] = $sessid;
    }
    print_r($_SESSION);?>
