I have a web service to which I send a xml request (application/x-www-form-urlencoded encoded) and get a response back. These are sent to the URL contained within a query parameter called ‘xml’
When I use a simple html form such as the one below, I am returned a result. However, when I use my php code, I am returned an error. Perhaps it is because of this: These are sent to the URL contained within a query parameter called ‘xml’? If that’s the case, how do I send it in that parameter? I’d be very grateful if someone could point out what I’ve been doing wrong. Many thanks
<form method="post" name="form1" action="http://webservicesapi.com/login.pl">
<textarea cols="80" rows="20" name="xml">
<?xml version="1.0"?><request><auth username="hello" password="world" /><method action="login" /></request>
</textarea>
<input type="submit" value="submit XML document">
</form>
This doesn’t work:
<?php
// open a http channel, transmit data and return received buffer
function xml_post($xml, $url, $port)
{
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$ch = curl_init(); // initialize curl handle
curl_setopt($ch, CURLOPT_URL, $url); // set url to post to
curl_setopt($ch, CURLOPT_FAILONERROR, 1); // Fail on errors
if (ini_get('open_basedir') == '' && ini_get('safe_mode' == 'Off'))
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // allow redirects
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable
curl_setopt($ch, CURLOPT_PORT, $port); //Set the port number
curl_setopt($ch, CURLOPT_TIMEOUT, 15); // times out after 15s
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml); // add POST fields
curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
if($port==443)
{
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
}
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$xml = '<?xml version="1.0"?><request><auth username="hello" password="world" /><method action="login" /></request>';
$url ='http://webservicesapi.com/login.pl';
$port = 80;
$response = xml_post($xml, $url, $port);
?>

CURLOPT_POSTFIELDS expects either an associative array, or a raw post string. Since you are passing it a string, it treats it as a raw post string. So either of these should work:
