[RESOLVED] output & header()

[saint4]

I have the following which I'm testing, after you login you will be presented with a "your login is being processed" + a animated image.

I would prefer not to use Javascript to redirect the user, is it possible to use header ('Location: '); because when i replace the javascript with it I get;

Warning: Cannot modify header information - headers already sent by

$file = fopen ('../sources/process_login.php', 'r');
	$read_file = fread ( $file, filesize ('../sources/process_login.php') );
	fclose ($file);

echo $read_file;
flush();
sleep (3);
echo '<script>window.location.href="../index.php"</script>';
exit;

eliminate any white space prior or after <?php ?>

There is no whitespace or html, that would have been the first thing I would have checked.

I'm thinking its because its displaying the html when it directs to the process login screen, so I would need to do something which gets rid of the output after x amount of secs and then redirects using header();

Something is being sent before your header. It is hard to tell you since I only see a fraction of your code in which the header function is not even included.

I assume you substitute the following with the header() function.

echo '<script>window.location.href="../index.php"</script>';

There is no whitespaces, no output of any kind and no html before this.

I've used the header location function in the majority of scripts I've written, so I know how to use it. Its just i've never had to use it in the way I need to now hence why i'm stuck and asking for help.

By the way its headers already started by this file on line 8

line 8 is: echo $read_file;

If you send anything to the screen before the redirect, regardless of how you do it, header() will not work.

I know that but as I said earlier I was wondering whether or not there is a function that will rid of the output or anything which I guess there is not.

So I will figure out something, thanks for the help.

ob_clean() will rid the output, but I really don't think this function would do anything in regards to your problem.

ok thanks anyway.

OK well i've scrapped it and just used what should have been the obvious

<meta http-equiv="Refresh" content="5; URL=siteurl" />

in the process_login page and will just create function which will alter the redirect url
