[wp-xmlrpc] XMLRPC for Wordpress Mu - blog_id parameter

Fri May 14 15:57:33 UTC 2010

Thanks again,

Can anyone confirm if the blog_id parameter should work in the wp.getComments call? This is what I'm doing to test it:

I've tried passing the blog ID as both a string and an integer. Wordpress MU version is 2.9.2

I always get the comments from the default blog.

<?php

error_reporting(E_ALL);

$method= 'wp.getComments';

$username = 'admin';

$password = 'disney75';

$blog_id = 2;

$params = array($blog_id, $username, $password, array('status'=>'approve'));

$service_url = 'http://wpmu.localhost/xmlrpc.php';

//Using the XML-RPC extension to format the XML package

$request = xmlrpc_encode_request($method, $params);

//var_dump($request);

$req = curl_init($service_url);

// Using the cURL extension to send it off,  first creating a custom header block

$headers = array();

array_push($headers,"Content-Type: text/xml");

array_push($headers,"Content-Length: ".strlen($request));

array_push($headers,"\r\n");

//URL to post to

curl_setopt($req, CURLOPT_URL, $service_url);

//Setting options for a secure SSL based xmlrpc server

curl_setopt($req, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($req, CURLOPT_SSL_VERIFYHOST, 2);

curl_setopt( $req, CURLOPT_CUSTOMREQUEST, 'POST' );

curl_setopt($req, CURLOPT_RETURNTRANSFER, 1 );

curl_setopt($req, CURLOPT_HTTPHEADER, $headers );

curl_setopt( $req, CURLOPT_POSTFIELDS, $request );

//Finally run

$response = curl_exec($req);

//Close the cURL connection

curl_close($req);

//Decoding the response to be displayed

var_dump($response);

For example, I use XML-RPC in all my plug-ins to report back installation progress and errors - each plug-in makes an XML-RPC call to a custom handler (method) on my server.
