PHP - Session, Post, Get Not Working

I try to use session to keep post data. It is not working. The program likes this .

html 

<select name="type">
   <option >for</option>
  <option value="PC">Photo copier</option>
      <option value="Fax">Fax</option>
      <option value="Copier">Copier</option>
      <option value="Cheque">Cheque</option>
     <option value="Print">Printer</option>
      <option value="Copier/Fax">Copier/Fax</option>
</select> <br />
PHP CODE

$session_start();
$_SESSION[brand]=$_POST[brand];
$_SESSION[sort]=$_POST[sort];
$_SESSION[type]=$_POST[type];


if (isset($_GET["page"])) { $page  = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * 18;


$select="select * from $chun where  brand = '$_SESSION[brand]' or  sort ='$_SESSION[sort]' or type='$_SESSION[type]'  LIMIT $start_from, 18";

$result2=mysql_query($select, $connection) or die (mysql_error());

$sql = "select count(*) from $chun  where   brand = '$_SESSION[brand]' or  sort ='$_SESSION[sort]' or type='$_SESSION[type]' ";
<div class="trunpage"><a href='table2.php?page=<?php echo  "$i" ; ?>&id=<?php echo "$_POST[brand]";?>&cd=<?php echo "$_POST[kind]";?>&td=<?php echo "$_POST[type]";?>'  ><?php echo  "$i" ; ?></a>
      
I get error message.

Notice: Undefined variable: session_start in C:\wamp\www\php1000\table2.php on line 174

Fatal error: Function name must be a string in C:\wamp\www\php1000\table2.php on line 174


Please tell me how to solve this problem . Thank you very much.

Well i have a session['rmanr'] a have set after a submit containing the date and unique id. I have to be able to do multiple submits on that same form but if they submit multiple times the same rmanr have to be used...   I tried the following:

$date         = date("Y-m-d");
$datestrip    = str_replace("-",  "", $date);
$lastdetid     = $dbh->lastInsertId();
if(!isset($_SESSION['rmamr'])){
            $rmanr                   = $datestrip;
            $rmanr                  .= $lastdetid;
            $_SESSION['rmanr']       = $rmanr;
        } else {
            $rmanr                   = $_SESSION['rmanr'];
        }

    $uprmastmt = $dbh->prepare("UPDATE rma SET r_nr = '$rmanr' WHERE r_id = ?");
    $uprmastmt->bindParam(1, $lastid);
    $uprmastmt->execute();

But i keep getting a new rmanr every time i submit... Could it be that my form submit reset my SESSION?

This topic has been moved to Third Party PHP Scripts.

It's been a while since I've needed to whip anything substantial up from scratch, so my scripting is a little (lot) fast and loose (weird/inefficient) here.

I'm trying to mock up a script that's essentially a quiz/survey. There are a handful of topics, each with a few screens of yes/no questions. At the end, it returns a list of recommendations based on the answers gathered.

The script is posting back to itself. Using print_r ($_SESSION), it seems like all of the post values for the first screen of questions are being assigned to the session array as expected. When the second screen of questions is answered, their values are assigned as well, but the values for the first set go away completely. This continues through subsequent screens, with the values from the previous screen present and all others before missing.

I'd really appreciate a look at my code to see if you tell me the cause or error(s).

Thanks!

I am using AJAX to access this file on my domain (weblyize.com), from my subdomain (ping.weblyize.com), and it keeps going into the if statement, logged is set on the domain, because I can see it when I go to a page that displays it. Anyone know why it is going into the if? If I go to the page directly, it works fine.

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Methods: POST, GET");
header("Access-Control-Allow-Headers: NCZ");
header("Access-Control-Max-Age: 1728000");
session_set_cookie_params(0, "/", ".weblyize.com", false); 
session_start();
if(!isset($_SESSION['logged']) || !$_SESSION['logged']){
header("HTTP/1.0 400 Bad Request");
header("Status: 400 Bad Request");
exit;
}
