An XML-RPC request cannot be treated as a classic request, thus you can't use "classic" request object. You have to create a specific entry point in www/ directory, xmlrpc.php. This entry point will instantiate a jXmlRpcRequest instead of a jClassicRequest.

Use the command app:create-entrypoint, by indicating the type xmlrpc:

php dev.php app:create-entrypoint --type=xmlrpc xmlrpc.php

It will create the entrypoint xmlrpc.php into your www/ directory, and will declare it into the urls.xml and framework.ini.php files.

You can then retrieve an url for a xmlrpc action like this:

  $url = jUrl::get("module~action@xmlrpc");

As XML-RPC is a specific request type, a controller filename must be suffixed by ".xmlrpc.php". A "default" controller file would be: "default.xmlrpc.php". (it can co-exists with a "default" classic controller such as "default.classic.php").

Controller content is similar to those of a classic controller. You just have to use a jResponseXmlRpc response (alias:"xmlrpc"):

class defaultCtrl extends jController {

  function index(){

    $resp = $this->getResponse('xmlrpc');

    // any data types : integer, string, array, objects...
    $data_php = ... ;

    $resp->response = $data_php;

    return $resp;

  }
}

To send a XML-RPC request, as specified in [[http://xmlrpc.scripting.com|xml-rpc spec]], you have to use a specific XML string:

<?xml version="1.0" ?>
<methodCall>
   <methodName>module:default:index</methodName>
  <params>
     <param><string>Allo ?</string></param>
  </params>
</methodCall>

The <methodName> element indicates which action to execute. In a Jelix application, it must be an action selector, here myModule:default:index.

Note: "~" cannot be used as separator between module name and action name. It must be replaced by ":" (tilde character is not permitted in XML-RPC method name). As a result, it is mandatory to indicate in the selector: a module, a controller and an action.

To retrieve received parameters in your controller, you will do:

  $parameters = $this->param('params');

Of course, $parameters will contain "php" data. The XML string is automatically decoded by jXmlRpcRequest.
