Message-ID: <1348574884.24022.12.camel@viator.rust.local>

Hi there.

I try to add a new xml-rpc function to wordpress but I can not get it
running.

Here my code (part of a plugin), to keep it simple I took an example
from the web:
<?php
/*
   Plugin Name: Franks WordPress Test Plugin
   Plugin URI: http://www.xxxxx.de/WP
   Description: Das ist mein allererstes WordPress Plugin
   Author: Frank Rust
   Author URI: http://www.xxxxx.de/WP
   Version: 0.0.3
*/

include_once(ABSPATH . WPINC . '/class-IXR.php'); 
include_once(ABSPATH . WPINC . '/class-wp-http-ixr-client.php'); 
 
add_filter( 'xmlrpc_methods', 'fwpr_add_new_xmlrpc_methods' );
function fwpr_add_new_xmlrpc_methods( $methods ) {
    $methods['demo.multiplyTwoNumbers'] = 'multiply_two_numbers';
    return $methods;
}
 
function multiply_two_numbers( $args ) {
    $first  = (int) $args[0];
    $second = (int) $args[1];
 
    return $first * $second;
}

// (...) lots of other code 

I'm running WP 3.4.2 (german).
The plugin is activated, other functions are working well.
And now when trying to call that 'demo.multiplyTwoNumbers' I get the
answer faultCode: -32601
faultString: server error. requested method  does not exist.

So what am I doing wrong? Missing some include or initialization? Is
there possibility to debug those xmlrpc calls?

Thanks in advance for any help,
best regards,
Frank

Hey,

First of all including IXR isn't needed at all. Don't think that causes issue tho. Looking at the code it does seems fine.
You can try to set WP_Debug on or check your php error log.

Looking at the error message, it looks like your XML RPC client is not
correctly calling the 'demo.multiplyTwoNumbers' method. The error
message includes the method being called, i.e. server error. requested
method METHOD_NAME does not exist.

Now I've got the solution. First, you are right, the calling program did
something wrong. 

After fixing that another fault was caused by the multi-site install:
if the ($current_site->domain != $_SERVER[ 'HTTP_HOST' ]) a redirect is
started and the xmlrpc call fails. 

Thanks for your help!

Subject: [wp-xmlrpc] Bug in xml-rpc code?
Message-ID: <1348847387.19103.57.camel@viator.rust.local>

I'm trying to get a comment via xml-rpc.

If I do it with wp.getComment I always receive 'error 404: invalid
comment id'. If I do wp.getComments the comment with the requested id is
among the results.

Example:

  $rpc = new WP_HTTP_IXR_Client( $this->test_url );

  $params = array(
                0,
                $this->remote_login,
                $this->remote_passwd,
array('filter'=>array('post_id'=>$pars['comment_post_ID'],'status'=>'','number'=>'','offset'=>0))
            );

  error_log("getComments( " .print_r($params,true) .") --");

  $rpc->query('wp.getComments',$params);
  $res = $rpc->getResponse();

  error_log("got from remote:" .print_r($res,true) .") --");

delivers to logfile: 

comment(Array
 (
     [0] => 0
     [1] => username
     [2] => PaSssword
     [3] => Array
         (
             [filter] => Array
                 (
                     [post_id] => 108
                     [status] => 
                     [number] => 
                     [offset] => 0
                 )
         )
 )
) --
got from remote:Array
 (
     [0] => Array
         (
             [date_created_gmt] => IXR_Date Object
                 (
                     [year] => 2012
                     [month] => 09

             [parent] => 47
             [status] => approve
             [content] => noch ein wort
             [link] => <some link...>
             [post_id] => 108
             [post_title] => Erster eigener&nbsp;Eintrag
             [author] => myname
             [author_url] => http://myblog.wordpress.com
             [author_email] => myname at mail.de
             [author_ip] => 89.182.x.x
             [type] => 
         )
     [1] => Array
         (
             [date_created_gmt] => IXR_Date Object
              :
              :
              :
         and so on
) --


BUT
  $rpc = new WP_HTTP_IXR_Client( $this->test_url );

  $params = array(
                0,
                $this->remote_login,
                $this->remote_passwd,
                array('comment_id'=>$pars['comment_ID'])
            );

  error_log("getComment( " .print_r($params,true) .") --");

  $rpc->query('wp.getComment',$params);
  $res = $rpc->getResponse();

  error_log("got from remote:" .print_r($res,true) .") --");

gives me:

getComment(Array
 (
     [0] => 0
     [1] => username
     [2] => PaSsword
     [3] => Array
         (
             [comment_id] => 50
         )
 )
) --

got from remote:Array
 (
     [faultCode] => 404
     [faultString] => Ung\xc3\xbcltige Kommentar-ID. 
 )
) --

So is this a bug or what could it be?


Thanks for any help,
Frank

The fourth argument to wp.getComment isn't an array, it is just the comment id:

wp.getComment( 'blog_id', 'username', 'password', 12345 )
