Drupal - Services PHP XML-RPC Example
Fri, 08/15/2008 - 08:13 — greg
So I read all I could about Drupal Services, I looked in the docs, I searched the group, I found no good info on a external to drupal PHP XML-RPC Client that connects to Drupal Services and interface with the node. Actually I found that the process of auth, node.load, and node.save are very poorly documented. So I am posting my findings.
I will update this as I investigate the search and other services.

Directions:
In Drupal turn on "Use sessid" - admin/build/services/settings
In your XML-RPC Clinet you will use the following methods: 1-2-3a or 1-2-3b or 1-2-3c
1. system.connect with no args
returns - session id
2. user.login
requires - session id from system.connect
3a. node.load
requires - session id from user.login
requires - nid
requires - array of fields, or empty array
3b. node.save (new node)
requires - session id from user.login
requires - type
requires - uid & name - if you want to associate to a user, otherwise it will be anonymous
optional - any other field you want to specify
3c. node.save (update node)
requires - session id from user.login
requires - type
requires - uid & name - if you want to associate to a user, otherwise it will be anonymous
required - revision - time()
required - created - time()
required - nid
optional - any other field you want to specify

Here is the sample code to connect, auth, node.load, node.save (new node), & node.save (update node)
Of course you should not run all of this at once.

$r = &$c->send($m);
if(!$r->faultCode()){
$v=$r->value();
$sessid = ($v['sessid']);
}else{
