Usually, when I have to redirect the user AFTER headers has been sent (like
showing an error message), I write this:
<SCRIPT>location=page_to_send.html</SCRIPT>
But this will redirect the user at once. If you want the user to read the
page, you should do something in Javascript with setTimeout(func,timeout)
function.

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.

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':...
}
?>
// more html and php
how can i fix this?
