Question

Is there any PHP class or resource for using Metaweblog api ?
I want to add this api to my own cms (like wp) so that other application could easily post (or …) throw it

Answer 1

Implementation of the MetaWeblog API http://www.xmlrpc.com/metaWeblogApi in PHP.

I looked to this script I linked for inspiration to develop the implementation I’m currently using. Feel free to use the example code below as an example of implementing the metaweblog API – but please consider using a modern XMLRPC library. I’ve included a link to a modified version of the original “xmlrpc.php” file that the example code requires.

Here’s the xmlrpc library the example code utilizes: XMLRPC library modified to work with PHP 5.4 – originally written by Keith Devens.

Doing a quick package search on packagist also provides many great options that are much more forward thinking in terms of PHP standards. ZendFramework2 even includes a component you can use in your project with minimal dependencies (10 packages – not the entire framework). I would strongly recommend that this example code, be used as such, and any new development be done with a modern XMLRPC library.

Adding the example code here in case the first link dies:

<?php
/**
 * Skeleton file for MetaWeblog API http://www.xmlrpc.com/metaWeblogApi in PHP
 * Requires Keith Devens' XML-RPC Library http://keithdevens.com/software/xmlrpc and store it as xmlrpc.php in the same folder
 * Written by Daniel Lorch, based heavily on Keith Deven's examples on the Blogger API.

require_once dirname(__FILE__) . '/xmlrpc.php';

function metaWeblog_newPost($params) {
  list($blogid, $username, $password, $struct, $publish) = $params;
  $title = $struct['title'];
  $description = $struct['description'];


  // YOUR CODE:
  $post_id = 0; // id of the post you just created


  XMLRPC_response(XMLRPC_prepare((string)$post_id), WEBLOG_XMLRPC_USERAGENT);
}

function metaWeblog_editPost($params) {
  list($postid, $username, $password, $struct, $publish) = $params;


  // YOUR CODE:
  $result = false; // whether or not the action succeeded


  XMLRPC_response(XMLRPC_prepare((boolean)$result), WEBLOG_XMLRPC_USERAGENT);
}

function metaWeblog_getPost($params) {
  list($postid, $username, $password) = $params;
  $post = array();


  // YOUR CODE:
  $post['userId'] = '1';
  $post['dateCreated'] = XMLRPC_convert_timestamp_to_iso8601(time());
  $post['title'] = 'Replace me';
  $post['content'] = 'Replace me, too';
  $post['postid'] = '1';


  XMLRPC_response(XMLRPC_prepare($post), WEBLOG_XMLRPC_USERAGENT);
}

function XMLRPC_method_not_found($methodName) {
  XMLRPC_error("2", "The method you requested, '$methodName', was not found.", WEBLOG_XMLRPC_USERAGENT);

$xmlrpc_request = XMLRPC_parse($HTTP_RAW_POST_DATA);
$methodName = XMLRPC_getMethodName($xmlrpc_request);
$params = XMLRPC_getParams($xmlrpc_request);

if(!isset($xmlrpc_methods[$methodName])) {
  XMLRPC_method_not_found($methodName);

  $xmlrpc_methods[$methodName]($params);
