Registration in php, session start and redirection

Question

I have the following registration.php file:

<?php 
include_once("QueryNew.php"); 

if (!get_magic_quotes_gpc()) {

$email=addslashes($_POST["email"]);
$password=addslashes($_POST["password"]);
$confirmpassword=addslashes($_POST["confirmpassword"]);
$uid=uniqid();

}

if (trim($email," ") == "" || trim($password," ") == "" && trim($confirmpassword," ") == ""){
    echo "<script type='text/javascript'>window.location='logintips.php?regErr=All fields are mandatory'</script>";
}

if (trim($password," ") != trim($confirmpassword," ")){
    echo "<script type='text/javascript'>window.location='logintips.php?regErr=Passwords didnot match'</script>";
}

if (trim($email," ") != "" || trim($password," ") != "" && trim($confirmpassword," ") != ""){

        $insertQuery = "INSERT INTO user VALUES('".$uid."','".$email."','".$password."','',1,".CURRENT_TIMESTAMP.")";
        $qry = new QueryNew();
        $insert = $qry->executeSelect($insertQuery);

        $SELECT_STAR = "select uid, email, timezone from ";

        $selectQuery = $SELECT_STAR . "user" . " where email = '".$email."'";

        $qry = new QueryNew();
        $select = $qry->executeSelect($selectQuery);

        while($row = mysql_fetch_assoc($select)) {
            $uidS = $row['uid'];
            $emailS = $row['email'];
        }

**//store $uidS and $emailS in a session variable and redirect to a (home) page**

}
?>

Once I am done with the insert and select queries, I want to create a session and redirect to someother page..

I tried session_start() as below:

        session_start();
        $_SESSION[uid] = $uidS;
        $_SESSION[email] = $emailS;

        echo $_SESSION[uid];
        echo $_SESSION[email];

Which gives an error:

**Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\xampp\htdocs\website\try\MAIN\HOME\QueryNew.php:43) in C:\xampp\htdocs\website\try\MAIN\HOME\register.php on line 45**

If there is a better way than the above, please suggest.

Original error message is zillion times better than something like "the above isnt working.. says session already created" — zerkms, Dec 30 '11 at 05:45
may be session_start() already defined in file so try removing that line — Sonal Khunt, Dec 30 '11 at 05:47
@MohitBumb: well.. thats why i have posted this question.. to find the answer somehow! — Kannan Lg, Dec 30 '11 at 06:07
@Mohit Bumb: you're wrong. This error means literally what is written - headers already sent. It has nothing to do with session started twice — zerkms, Dec 30 '11 at 06:52

Read your error message.

QueryNew.php is generating some output (at line 43). You should not echo or print anything before you start your session. You could start the session before you include QueryNew.php though.

thanks.. but is there a way to "create a session with the db values and redirect to someother page (say home page)" – Kannan Lg Dec 30 '11 at 05:50
i checked that question.. there is only one tag in my complete file! – Kannan Lg Dec 30 '11 at 06:05
You can do this by calling ob_start() and ob_end_flush() in your script, or setting the output_buffering configuration directive on in your php.ini or server configuration files. – Pradeep Singh Dec 30 '11 at 06:08
A good design won't need output buffers, if you come to using OB then you should consider a redesign of your architecture! – Paul Dec 30 '11 at 12:02

<?php ob_start();
if(session_id()){
//Session is already started
}else{
session_start();
}
?>

Just put ob_start() in top of the page will resolve this error
