Problem using curl_setopt for redirection

[Marek Möhling]

I'd like to redirect visitors to a remote location sending post values.


Using:

=============== =============== =============== =============== ====
$ch = curl_init();
curl_setopt($ch , CURLOPT_URL,
"http://www.ihk-bonn.de/handelsregister/");
curl_setopt($ch , CURLOPT_POST, 1);
curl_setopt($ch , CURLOPT_POSTFIE LDS,
"amtsgericht=&d ateYear=2004&mo nthsNr=&registe rart=".
"&cursorStepVal ue=5&orderby=Ha ndelsregister-Nr.".
"&suchword=kast enholz&s=1&sear ch=www.ihk-bonn.de");
curl_exec($ch);
=============== =============== =============== =============== ====

I can retrieve www.ihk-bonn.de's response and print it to the browser, (see
www.peterkastenholz.de/test.php) but what I want is to redirect to
"www.ihk-bonn.de/handelsregister/" with my POST values and the corresponding
result.

I couldn't find code to do this on
www.php.net/manual/en/function.curl-exec.php or curl.haxx.se etc.

Using fsockopen/fputs directly didn't help - same result. Output
buffering prevented the result from being printed to the browser, but I
couldn't fiddle a redirection.

Any clues?

What you are trying to do can only be achieved by either passing the
arguments to the target host through a Location header (the host should
accept GET requests in this case) or by putting the arguments in a form that
auto-submits (e.g. with JavaScript).

Actually the host in question accepts both POST and GET, but it's form is
set to method="POST", so I guess the GET option is unintentional and can't
be relied on. (they might turn off register_global s eventually...)

Yes, but this is unconvenient when JS is turned off and wouldn't allow to be
triggered by cronjobs.

I still hope that the header() function provides a solution.

Thinking again, this:[color=blue]

was not so well thought of me

But:[color=blue]

is still a valid concern

Thinking again again, it really can't be done as I'd like it to...:-(
