Using xmlRPC calls in my Wordpress Plugin PHP + Avoid Curl / use HTTP API?
WordPress includes a XML-RPC class (IXR), it's a matter of
include 'wp-includes/class-IXR.php'; // better with: ABSPATH . WPINC . '/class-IXR.php';$client = new IXR_Client( 'http://example.com/xmlrpc.php' );if( !$client->query( 'demo.sayHello', array() ) ) echo $client->getErrorMessage();else echo $client->getResponse();And for authenticated requests:
$query_args = array( 'post_status' => 'publish', 'post_type' => 'post', 'number' => 3);$args = array( '', // blog_id 'username', 'password', $query_args); $result = $client->query( 'wp.getPosts', $args );
