Submitting POST data without FORM

[iansilber]

I have a form that routes to a PHP script that sends an email. I have this set up fine, but here's the tricky part:

I need to then have it send the same variables to a third-party script that will only accept POST variables, so the get method is out of the question.

Is there a way to do this?

Sorry if it's completely easy, I'm pretty much a noob.

Thanks for the link. I tried using that script, but I kept getting different errors. Is there an easier way, or does someone have a working script that you could show me?

Thanks, Ian

Okay, well I found a way to do it, using cURL (which I do have installed on my server). Here's the code:

$URL="www.theurl.com/script.php"; 
$ch = curl_init();___ 
curl_setopt($ch, CURLOPT_URL,"https://$URL"); 
 curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, "email=$emailaddress&firstname=$firstname&lastname=$lastname");curl_exec ($ch);____ 
curl_close ($ch); 

But when I do it, I get the following error message:

Parse error: parse error, unexpected T_STRING in /home/msilber/public_html/mailform.php on line 4

Line 4 is: curl_setopt($ch, CURLOPT_URL,"https://$URL");

I can't figure out what's wrong here. Anybody know?

This is a modified version of something from I think the Zend site - it also reads back the page as I needed that feature.

datastream is an associative array.

function get_via_post($url, $datastream)
{
	$url = preg_replace("@^[url]http://@i[/url]", '', $url);
	$host = substr($url, 0, strpos($url, '/'));
	$uri = strstr($url, '/'); 

$result=NULL;
$reqbody = '';

foreach($datastream as $key=>$val)
{ 
	if (!empty($reqbody)) $reqbody.= '&'; 

	$reqbody.= $key."=".urlencode($val); 
} 

$contentlength = strlen($reqbody); 

$reqheader ="POST $uri HTTP/1.1\r\n". 
			"Host: $host\n".
			"User-Agent: PostIt\r\n".
			"Connection: close\r\n".
			"Content-Type: application/x-www-form-urlencoded\r\n". 
			"Content-Length: $contentlength\r\n\r\n". 	// DOUBLE return here
			"$reqbody\r\n";

$socket = fsockopen($host, 80, $errno, $errstr);

if (!$socket)
   return $result;

fputs($socket, $reqheader);

$result=read_http_response($socket);

fclose($socket);

return $result;
}


//read the whole lot in one go - then break up if chunked
function read_http_response($socket)
{
	$data   = NULL;
	$result = NULL;
	$header = NULL;

	//read the header
do
{
	$header.= fgets($socket, 4096);
	$stream = stream_get_meta_data($socket);
	if ($stream['eof'] == 1) break;
}
while (!preg_match('/\r\n\r\n$/',$header));

	//read the data	
while(1)
{
	$result .= fread($socket, 4096);
	$stream = stream_get_meta_data($socket);
	if ($stream['eof'] == 1) break;
}

	//if data is not chunked then just return
if( !preg_match('/Transfer-Encoding:\s*chunked\r\n/i',$header) )
	return $result;

$offset=0;

while(1)
{
	$byte='';
	$chunk_size='';

	do
	{
		$chunk_size.=$byte;
		$byte=$result{$offset++};						
	}
	while ($byte!="\r");      // till we match the CR

	$offset++;        // also drop off the LF
	$chunk_size=hexdec($chunk_size);

	if($chunk_size==0) break;

	$data.=substr($result, $offset, $chunk_size);		
	$offset+=$chunk_size+2;	//also go past CRLF at end of chunk
}

return $data;
}
