PostToHost()-Problem

Anon

Hi!
I am trying to get a little bit less workload with the PostToHost-function.
Here is what I want to do: When someone signs up for my site and indicates that we wants to get the newsletter, I need to post the data the user submitted to two different hosts:
a) to my database
b) to topica.com
Right now I'd have to get the data I got by E-Mail (which is only an e-mail-address) and enter it into a form from topica manually.
So, here is my code, which isn't working:
<?
function PostToHost($host, $path, $data) {
$fp = fsockopen($host,80);
printf("Open!\n");
fputs($fp, "POST $path HTTP/1.1\n");
fputs($fp, "Host: $host\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\n");
fputs($fp, "Content-length: ".strlen($data)."\n");
fputs($fp, "Connection: close\n\n");
fputs($fp, "$data\n");
printf("Sent!\n");
while(!feof($fp)) {
$res .= fgets($fp, 128);
}
printf("Done!\n");
fclose($fp);

return $res;
}

$data = "?digest=f&Submit=Submit&sublist=dummy@online-talks.de&invite=OPTOUT";

printf("Go!\n");
$x = PostToHost(
"www.topica.com",
"/lists/online-talks.de-english/importsub.pl",
$data
);
?>
Here is the data I see on my topica-form (the one where I enter data by myself usually):

<HEAD><TITLE></TITLE></HEAD>
<BODY>
<FORM METHOD="POST" ACTION="/lists/online-talks.de-english/importsub.pl" ENCTYPE="multipart/form-data">
Addresses:<TEXTAREA NAME="sublist" ROWS=5 COLS=40 WRAP=PHYSICAL></TEXTAREA><br>
<INPUT TYPE=RADIO NAME=invite VALUE="OPTOUT" CHECKED>Add Directly to List
<SELECT NAME=digest>
<OPTION VALUE='F'>Individual Messages
</SELECT>
<INPUT TYPE="submit" NAME="Submit" VALUE="Submit">
</FORM>
</BODY>

I hope someone can help. Thanks in advance.🙂
Ciao

Try to replace
fputs($fp, "$data\n");
by
fputs($fp, "$data");

and

$data = "?digest=f&Submit=Submit...
by
$data = "digest=f&Submit=Submit...

Tell me if it works!

Hi.

I've came across with the problem as well and I wonder if you have the solution already ?

What I want to do is to invoke a php script from another server via http post with some variables passing to it. Let me show you my script, I'm using what sascha has written :

<?
filename: posttohost.php

    function PostToHost($host, $path, $data) 
    {
            $fp = fsockopen($host,80);            
            printf("Open!\n");            
            fputs($fp, "POST $path HTTP/1.1\n");            
            fputs($fp, "Host: $host\n");            
            fputs($fp, "Content-type: application/x-www-form-urlencoded\n");            
            fputs($fp, "Content-length: ".strlen($data)."\n");            
            fputs($fp, "Connection: close\n\n");            
            fputs($fp, "$data");              
            printf("Sent!\n");            

            while(!feof($fp)) 
            {
                    $res .= fgets($fp, 128);    
            }            
            printf("Done!\n");            
            fclose($fp);            

            return $res;            
    }                    

    $data = "login=bbbear&var=abctesting";                                                          

    printf("Go!\n");                    
    $x = PostToHost("192.xxx.xx.xxx", "/home/path/to/the/script.php", $data);                                 ?>

And here's the content of the script.php:

<?
//To create a new file with the data that passed from other server

   srand((double)microtime()*1000000);
    $file = rand();
    $ar_var[0] = $login;
    $ar_var[1] = $var;
    $str = join($ar_var, ";");

    $fp = fopen($file, "w");
    fwrite($fp, $str, strlen($str));
    fclose($fp);

When I run the script "posttohost.php", the browser shows this line "Go! Open! Sent! Done!" but there's no new file being created on the server that I've given to the function. Have I missed anything ?

Anyway, is there any other alternatives that can be adopted for "server-to-server talk" kind of application ?

Thank you very much.
