I'm kinda surprised I didn't see this mentioned.. Have you tried:
header(Location: http://url.redirect/\n\n;); exit; // ?

The browser may be particular about the headers. When you add the two 
newlines to the end, it makes it look like the end of the headers.

It's good practice to explicitly exit each time you redirect.

You should definitely not try to add your own newlines to the end of a
header like that. PHP might be able to gracefully handle it, but I
wouldn't rely on it.

As for the original question, put a space after your colon, and let us
know how that works.

Hope that helps.

[PHP] header function, I'm stumped

2003-12-02 Thread Chris Hubbard 
All,
dealing with header(location:...) again.  and trying to understand what's
happening.

I've got the following code:

writeMessage($id);
header(Location:http://www.mysite.com/cp/ad/ad_details.php?id=;. $id);

writeMessage() is a debugging function that writes the value of the variable
to a debug log.  When the code is run $id does have a valid value like 8 or
12.

When I run the code, it does not redirect to the specified location, it
continues executing the code.

So I add the exit; and it does work:

writeMessage($id);
header(Location:http://www.mysite.com/cp/ad/ad_details.php?id=;. $id);
exit;

What's weird is the same code without the exit works on a different server
(and indeed the same code with different location works on this server)

I thought perhaps it was due to type problem, but code doesn't work if $id
is a string or integer.

The flow for the code:
start the edit page
when edit page is submitted,
check the data,
if data is good,
update the database
redirect to details page
if data is bad,
return to the edit page

Then I used LiveHTTPHeaders in Mozilla and it give me some interesting
information, though I'm not quite sure how to interpret.

Can someone provide some depth to the mechanisms within the
header(location)?

Thanks in advance,

Chris Hubbard

There should be a space after the first colon there.

Awesome. Paste that here (you can omit the bulk of the HTML, so that
there's not too much stuff to sift through), and we can help you interpret
it. What would be best is to try and trim it down to only what is
different between when it works and when it doesn't.
