PHP Script for XML-RPC calls from outside Drupal
Here is a set of PHP functions I put together for calling Drupal's core XML-RPC methods without using the Services API:
<?php
function assemble_request($method, $args = array(), $dump_request = FALSE){
$request = xmlrpc_encode_request($method,$args);
$context = stream_context_create(array('http' => array(
'method' => "POST",
'header' => "Content-Type: text/xml",
'content' => $request
)));
if($dump_request){
echo '<pre>';
echo htmlentities($request);
echo '</pre>';
}
return $context;
}
function dump_response($response){
echo '<pre>';
if (xmlrpc_is_fault($response)) {
trigger_error("xmlrpc: $response[faultString] ($response[faultCode])");
} else {
print_r($response);
}
echo '</pre>';
}
function make_args_array($method, $session, $args = array(), $dump_args = FALSE){
$domain = 'localhost';
$timestamp = (string) time();
$nonce = user_password();
$key = '4a13889853ed635941670fe6054a9759';
$hash = hash_hmac('sha256', $timestamp .';'.$domain .';'. $nonce .';'.$method, $key);
$arrHash = array();
array_push($arrHash, $hash, $domain, $timestamp, $nonce, $session);
if($dump_args){
echo '<pre>';
var_dump(array_merge($arrHash,$args));
echo '</pre>';
}
return array_merge($arrHash,$args);
}
function user_password($length = 10) {
$allowable_characters = 'abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ23456789';
$len = strlen($allowable_characters) - 1;
$pass = '';
for ($i = 0; $i < $length; $i++) {
$pass .= $allowable_characters[mt_rand(0, $len)];
}
return $pass;
}
?>Here is an example use that logs in a user and returns a node:
<?php
$ctxtSysConnect = assemble_request("system.connect", NULL);
$file = file_get_contents("http://localhost/drupal/xmlrpc.php", false, $ctxtSysConnect);
$response = xmlrpc_decode($file);
$session = $response[sessid];
$arrArgs = make_args_array('user.login',$session,array("username","password"));
$ctxtSysConnect = assemble_request('user.login', $arrArgs);
$file = file_get_contents("http://localhost/drupal/xmlrpc.php", false, $ctxtSysConnect);
$response = xmlrpc_decode($file);
$session = $response[sessid];
$arrArgs = make_args_array('node.view',$session,array(11,array("field_date")),TRUE);
$ctxtSysConnect = assemble_request('node.view', $arrArgs);
$file = file_get_contents("http://localhost/drupal/xmlrpc.php", false, $ctxtSysConnect);
$response = xmlrpc_decode($file);
dump_response($response);
?>If you're interested in working on making CCK date fields work with Drupal's "node.save" function, get in touch with me through my Drupal Groups user page.

I am using Fedora 10, PHP
I am using Fedora 10, PHP 5.2.6. However my PHP does not understand xmlrpc_encode_request(). It said: "PHP Fatal error: Call to undefined function xmlrpc_encode_request() in /home/chau/public_html/tmp/rpc.php on line 5".
On the other side, php.net says xmlrpc_encode_request() is still in experimental stage (http://vn.php.net/xmlrpc_encode_request). Any other way to call XML-RPC from outside Drupal to Drupal? Thanks.
