How to post categories to Wordpress using metaWeblog.newPost

Hi all,

I've started using metaWeblog.newPost to post to my wordpress blog using XMLRPC as it handled posting tags as well.

According to the metaweblog API spec for XMLRPC it says

metaWeblog.newPost (blogid, username, password, struct, publish) returns string

(within struct)

For categories, pass an array of strings of names of categories that the post belongs to, named categories. On the server side, it's not an error if the category doesn't exist, only record categories for ones that do exist.

http://www.xmlrpc.com/metaWeblogApi

I have attached my code, and a couple outputs from running it. I have tried passing either the ID of category (528) or the name (Accommodation) and neither worked. It posts correctly, just never manages the category. I can use a mt.setCategory or similar but I'm looking to get this working.

CODE


function wpPostXMLRPC($title,$body,$categories,$tags=""){
	$rpcurl = "http://debian/blog/xmlrpc.php";
	$username = "admin";
	$password = "password";
	$categories = implode(",", $categories);

    $content = array(
        'title'=>$title,
        'description'=>$body,
        'mt_allow_comments'=>1,  // 1 to allow comments
        'mt_allow_pings'=>1,  // 1 to allow trackbacks
        'post_type'=>'post',
        'mt_keywords'=>$tags,
        'categories'=>$categories
    );
	
	print_r($content);
	
    $params = array(0,$username,$password,$content,true);

	$request = xmlrpc_encode_request('metaWeblog.newPost',$params); //new
	
	$ch = curl_init();

	curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
	curl_setopt($ch, CURLOPT_URL, $rpcurl);
	curl_setopt($ch, CURLOPT_VERBOSE, 1);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_TIMEOUT, 60);
	
	$output = curl_exec($ch);
	
	if ($output === false) {
		echo "Curl failure";
	} else {
		echo "Curl success, result: \n\n";
		echo $output;
	}
	curl_close($ch);
