Hi,

following problem is bugging me for some time now.

I would like to post data to two sites (one is mine (thats all clear) and another is .asp web server (have no control over it)).

My design looks like this:
a.php (form post) --> b.php (all vars are inserted to my database) --> c.asp (foreign site) --> d.asp(foreign site)

I'm trying with Curl to post vars from b.php to c.asp.
Main problems are ...
... when foreign site receives data from <c.php>, goes to <d.asp> and adds id=xxxx in url, which I also need to store in my database
... when Id is saved, more data (allways the same values) must send to d.asp to complete signup.

Did anyone try something like that (some example perhaps), Examples I saw can not read vars from url, and some other problems.

Regards ...

my b.php file looks like this
// ---- start -------------------------------------------
        $postfields = array();
        $postfields[] = array("znamka", 'Audi');
        $postfields[] = array("model", '80');
        $postfields[] = array("tip", 'elite');
        $postfields[] = array("letnik", '1980');
        $postfields[] = array("modelnoleto", '1981');
         
        foreach($postfields as $subarray) {
             list($foo, $bar) = $subarray;
             $bar = urlencode($bar);
             $postedfields[]  = "$foo=$bar";
        }
         
        $urlstring = join("\n", $postedfields);
        $urlstring = ereg_replace("\n", "&", $urlstring);
        echo $urlstring;
                                          
        $ch = curl_init("http://www.somesite.com/c.asp");
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $urlstring);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
        curl_setopt($ch, CURLOPT_REFERER, "http://www.somesite.com/x.asp");
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $data = curl_exec($ch);
        curl_close($ch);

// ------------- end sending data ---------------

You can use preg_match to get that id out of the html-code.

if (preg_match('/\bid=(\d+)\b/', $data $m)) {
    echo "id = " . $m[1];
}

For further help the content of $data would be interesting

May I suggest another solution?

I figured you have one page containing the form:

<form method="post" action="myhandler.php"> //or something alike

You could implement an frame/iframe and then submit the form to this frame using target

<iframe name="myiframe"></iframe>
<form method="post" action="myhandler.php" target="myiframe">

You could now have myhandler.php output something like:
<script>
parent.forms[0].target="_self";
parent.forms[0].action="remote_asp.asp";
parent.forms[0].submit();
</script>

Then after the data has been submitted to the frame - the original form still present at the original page - you just tell the original page to resubmit itself, after interpreting the data using your own php.
