redirect

[alain dhaene]

Hi,

What's wrong with that?

I have a variable

$order_nummer = "C.45";

Then I redirect to

header('Locatio n: xmlorderon.php? order_id=$order _nummer');

but I my location bar I see:

http://localhost/pcGebruik/files/xmlorderon.php? order_id=$order _nummer


thx
Alain

Re: redirect

Use double quotes instead.
" instead of ' in your header argument.

The contents of single quotes are taken literally (with two exceptions).

echo 'the variable a holds $a'; // taken literally
echo 'it\'s a exception'; // the \' is taken as a single '
echo 'the other exception is \\ a single backslash';


So to have your header() do what you want either use double quotes
(which interpolate much more than single quotes) or concatenate the
contents of $order_nummer to the rest of the URL:

header('Locatio n: xmlorderon.php? order_id=' . $order_nummer);

Better yet is to use urlencode() for the $order_nummer:

header('Locatio n: xmlorderon.php? order_id=' . urlencode($orde r_nummer));

And even better would be the use of a valid syntax for the location.

header('Locatio n: http://www.example.com/xmlorderon.php? order_id=' .
urlencode($orde r_nummer));

According to http://www.php.net/manual/en/function.header.php HTTP/1.1
requires an absolute URI as argument to Location: including the scheme,
hostname and absolute path, but some clients accept relative URIs. So
with the short version it might work on some clients and fail on others
and that's not what you want. :-) Use the correct version and it will
run anywhere.

Matthias

Right. Thank you for the correction.

The W3C (World Wide Web Consortium) says the same thing about the
Location: header:

http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.30
