Question

I am working on how to redirect to another page by suing header() function, but it’s not working, and give me an error message saying hat:Cannot modify header information – headers already sent by…… Anyone could help, thanks a lot.
here is my php code

 if(isset($_POST['email'])){
    $email = $_POST['email'];
    $pass = $_POST['pass'];
     $query = "select email, password from member where email = '$email' and   password='$pass'";
     if(mysql_num_rows(queryMysql($query)) == 0)
{
   echo "Email/Password invalid<br/>";
}
else
{
    $query1 ="select uniid from member where email = '$email' and password ='$pass'";
     $result1 = queryMysql($query1);
      $row1 = mysql_fetch_object($result1);
      $uniid = $row1->uniid; 
       $_SESSION['uniid'] = $uniid;

       header("Location:View.php?view=$uniid");
   }
     }

Consider starting your code with ob_start(). This turns off output buffering, which in short allows you to use header() and setcookie() anywhere at all.
