Re: header problem

Hi Blueman. As soon as ANYTHING has been drawn to the browser, you cannot use a header command. So you need to work through all of your code, and ensure that all of your logic that could result in a header call is run BEFORE you send any html code. Is going to be tricky if mixing html and php calls. George On 10-Sep-09, at 12:27 AM, A.a.k wrote:

hello I recentrly uploaded my project from localhost to a hosting and found many errors and warnings which didnt have in local. one of the most annoying one is header('Location xxx'). I have used header to redirect users from pages, and kinda used it alot. i know about the whitespace causing warning, but most of the pages i'm sending users got html and php mixed so i'm confused about how to remove whitespace in a html/php file. the error is : Warning: Cannot modify header information - headers already sent by .... here is a simple example, user update page : if($valid)

                  {
                      $msg='111';
                      $user->dbupdate();
                       header("Location: /admin/index.php?msg=$msg");

                  }
                  else
                  {
                       foreach($errors as $val)
                          echo '<p id="error">'.$val.'</p>';
                  }

and on admin index i get $msg and display it. <html> ...... //lots of stuff <?php

                 $msg = $_GET['msg'];
                         switch($msg){
                         case '111'       echo '<p> </p>';
                                      break;
                        case '421':...
                  }
