[RESOLVED] Some header() issues

stormszero

Hi,

I am having a bit of problems with the header() function. I am trying to do a simple script that redirects to a certain case id.

Javascript (location.href) is not possible (at least not with my knowledge of javascript) since it has to work on Windows 2003 Server, and it ignores/blocks/prevents this javascript.

So, I turned to header() and with the respective ob_start() and ob_end_flush() it works well in standard.

Works:
header("Location: list.php");

Does not work:
header("Location: list.php?id=$id");
(simply assume $id is a number)

Is there anything I have missed regarding header? Can i get this to work or can it be done in another way?

Thanks in advance!

I doubt if this is the source of the problem, but the HTTP/1.1 spec. says that the Location header should always be a full URI, so you should be using:

header("Location: http://www.example.com/list.php?id=$id");

But, if one is working and one is not, with the only difference being the presence of the URL query string, my guess is there is some other problem in the code rather than the header() command.

I have just tried with both absolute and relative links, both to no avail.
$id is passed through a form and snatched into a variable.

This functionality is part of a login script, which works perfectly fine.
If an id has been defined, it should redirect to overview.php?id=x instead of listing cases (list.php). Ordinary list-redirect is working without problems at all.

As mentioned, if I change the header and remove the ?id=$id part, the header works fine. This is what confuses me, pointing to the fact that something I'm doing is not valid - but I don't know what - and if so - how to fix it.

// id defined, header fails to redirect
// ** if you remove ?id=$id the redirect will work! **
$id = $_POST["redirect_case_id"];
header("Location: http://thefullurl.com/overview.php?id=$id");

// id not defined, regular redirect - no problem
header("Location: http://thefullurl.com");

You may need an exit; after the first location header() if your code logic allows the second header() command to run after the first, as it would then supersede the first one.

Why of course! I should have spotted that immediately.
Truth be told, the above is not the exact code as I was not at home, so it was mostly an example of what worked and what didn't.

I re-wrote some of my code to take it into consideration which I had forgotten before. It seems to work now. Thank you very much!
