Using Blog API's

Almost every standard compliant blogs support three blogging API which are “Blogger API” , “MovableType API” and “MetaWeblog API”. Among these three, MW (or MetaWeblog) is used more than other two. WordPress also supporst these three sets of API. If you are interesetd how to interact with these API’s – then take a look at the following example.

First lets discover which XMLRPC methods are suported by wordpress XMLRPC server. After digging a bit further we found that the following methods are supported

system.multicall
system.listMethods
system.getCapabilities
demo.addTwoNumbers
demo.sayHello
pingback.extensions.getPingbacks
pingback.ping
mt.publishPost
mt.getTrackbackPings
mt.supportedTextFilters
mt.supportedMethods
mt.setPostCategories
mt.getPostCategories
mt.getRecentPostTitles
mt.getCategoryList
metaWeblog.getUsersBlogs
metaWeblog.setTemplate
metaWeblog.getTemplate
metaWeblog.deletePost
metaWeblog.newMediaObject
metaWeblog.getCategories
metaWeblog.getRecentPosts
metaWeblog.getPost
metaWeblog.editPost
metaWeblog.newPost
blogger.deletePost
blogger.editPost
blogger.newPost
blogger.setTemplate
blogger.getTemplate
blogger.getRecentPosts
blogger.getPost
blogger.getUserInfo
blogger.getUsersBlogs

so to make a new post using metaWeblog.newPost method lets take a look at the following example.

<?php
	include("xmlrpc.inc.php");
	$c = new xmlrpc_client("/wp/xmlrpc.php", "localhost", 80);

	$content['title']="XMLRPC Post";
	$content['description']="Some content posted using MetaWeblog API";
	$content['categories'] = array("frontpage");
	$x = new xmlrpcmsg("metaWeblog.newPost",
	                    array(php_xmlrpc_encode("1"),
                        php_xmlrpc_encode("admin"),
                        php_xmlrpc_encode("root"),
                        php_xmlrpc_encode($content),
                        php_xmlrpc_encode("1")));

	$c->return_type = 'phpvals';
	$r =$c->send($x);
	if ($r->errno=="0")
	echo "Successfully Posted";
	else {
		echo "There are some error";
		print_r($r);
              }
?>

Thats it!!

  2. isnt somewhereinblog based on wordpress 2.0? It is already opensource and support metaweblog API. All you need to develop a web based GUI for them. Or create user ID for each of them and inform their user ID. They can implement access our blog using Blog APIs.

    have you ever been to http://m.wordpress.com [For mobile] ? We could have something like that.

  3. Hi,

    where can I get ‘xmlrpc.inc.php’ and ‘/wp/xmlrpc.php’??

    /wp/xmlrpc.php – is the same using by WordPress PHP Script??

    To use this code I need xmlrpc_client CLASS, right??

    I want to setup a simple PHP Script to load from RSS Feed and use MetaWeblog API to Post to some Blog.

    I may use this Script????

    Thanks in advance,

    m.

  8. Thanks you Hasin. I was struggling with Blogger API as the title wasn’t getting set when posting to wordpress. The code stub you gave works wonderfully well. Still have problems with the categories though. Couldnt figure that out. If you can mail me how to set categories in these posts, that would be lovely. Thanks a lot !! Cheers!!

  10. Hi Hasin,
    thanks a lot for your example.
    My question is: how do you get the allowed element lists to populate $content array (I mean … where is described the struct?)
    thanks

  35. This works great for my wordpress stuff, but I’m trying to figure out how to set the content such that it will schedule the post for a future date/time. Any ideas what I need to set in content?
