POST method through PHP

mhrasel

Hi,
This is M H Rasel from Bangladesh. I am trying to redirect to another page with some variable as POST variable. i try to use the following code for doing that.

<?php


$host = "www.acmbeginner.org/";
$path = "/action.php";
$data = "data1=value1&data2=value2";
$data = urlencode($data);

header("POST $path HTTP/1.1\r\n" );
header("Host: $host\r\n" );
header("Content-type: application/x-www-form-urlencoded\r\n" );
header("Content-length: " . strlen($data) . "\r\n" );
header("Connection: close\r\n\r\n" );
header($data);

?>

i save this code as index.php and i develop the action.php as redirect page. i host this script also on the domain acmbeginner.org . But when i run the script i get an internal Server Error like following

[CENTER]The server encountered an unexpected condition which prevented it from fulfilling the request.
The script did not produce correct headers. It must at least print out a Content-Type header, like so:
Content-Type: text/html

The header the script produced was:
POST /action.php HTTP/1.1[/CENTER]

Can anyone tell me how can i solve this problem.

I have little knowledge in this area, but there are a two things I'd try.
- Get rid of all your \r\n: PHP sends a newline after each header, so unless that's only sent if your header does not end with a newline, then you end up with two consecutive newlines, which ends the header part of the message according to the HTTP 1.1 spec. If you use fputs instead of header, then you will have to deal with newlines yourself.
- Get rid of the trailing / for the host field value.

Another thing; the $data is not a header.

$data = "data1=value1&data2=value2";
$data = urlencode($data);

header("POST $path HTTP/1.1" );
header("Host: $host" );
header("Content-typ: application/x-www-form-urlencoded" );

As Weedpacket pointed out, header($data) is not a header at all. fputs it instead.

Hi,
Thanks once again for your help.
I removed that part from the code now. here is the code. But still the same problem.
$host = "www.acmbeginner.org";
$path = "/action.php";
$data = "data1=value1&data2=value2";
$data = urlencode($data);

header("POST $path HTTP/1.1" );
header("Host: $host" );
header("Content-typ: application/x-www-form-urlencoded" );
header("Content-length: " . strlen($data) . "" );
header("Connection: close\r\n" );

will puts redirect me? Would u pls give me a code sample for puts.

Regards.

It's fputs (or fwrite), not puts.
example

And no, it will not redirect anyone. Redirections are handled by headers:

HTTP/1.1 302 Moved Permanentely
Location: http://someplace.else.com/someresource

You've misspelled "Content-Type:"

You also have a \r\n in the headers still.

IceRegent

a correct header redirect should be : header ("Location: url")

Installer

The header() function is used to generate http response headers; "POST" belongs in a request line, and "Host:" and "Connection:" belong in the request, not response, header. As IceRegent said, use "Location:" for a redirect header.
