Using Blog API – Part 2: Get Categories and Posts

Written by hasin

In our first part we just discussed what is a blogging API and how we can utilize them. In this post I am going to show how to fetch available categories in a blog and how to retrieve a specific post.

To retrieve available categories you have to use metaWeblog.getCategories as shown below

<?php
	include("xmlrpc.inc.php");

	$c = new xmlrpc_client("/xmlrpc.php", "hasin.wordpress.com", 80);
	$c->return_type = 'phpvals'; // let client give us back php values instead of xmlrpcvals

	echo "<pre>";

	$x = new xmlrpcmsg("metaWeblog.getCategories",array(php_xmlrpc_encode("1"),
	                                     php_xmlrpc_encode("someusername"),
	                                     php_xmlrpc_encode("somepassword")));


	$r =$c->send($x);
    if ($r->errno=="0")
	print_r($r);
?>

And To retrieve a specific post you have to metaWeblog.getPost API as shown here

<?php
	include("xmlrpc.inc.php");

	$c = new xmlrpc_client("/xmlrpc.php", "hasin.wordpress.com", 80);
	$c->return_type = 'phpvals'; // let client give us back php values instead of xmlrpcvals

	echo "<pre>";

	$x = new xmlrpcmsg("metaWeblog.getPost",array(php_xmlrpc_encode("1"), //postId
	                                     php_xmlrpc_encode("someusername"),
	                                     php_xmlrpc_encode("somepassword")));


	$r =$c->send($x);
    if ($r->errno=="0")
	print_r($r);
?>
