AS3 Library for the WordPress API

I’m sorry to say that I no longer have the time nor the inclination to update this library – please feel free to download for any personal, commercial, or other use, but I will no longer be updating this page or the source code.

Hi there.

I’ve developed an (almost) fully featured ActionScript library for WordPress XML-RPC, that any flash developer can use to build flash front-ends for WordPress managed sites. The library builds on the work of Akeem Philbert (who developed this excellent XML-RPC library), and is designed to make connecting Flash with WordPress easy and straightforward.

About the library

I developed this for the simple reason that there didn’t seem to be one available. I wanted a WordPress service that could make sensible method calls in an easy way rather than having to pass everything through XMLRPCObject, and I wanted results that would be strongly typed versions of the XML-RPC results, with separate event types for each call. My WPService class does exactly that, and I hope some of you out there find it useful.

Download: » version 1.01

Requirements

Akeem Philbert’s XML-RPC Library (included in the download)
The Flex2 SDK

Documentation

Documentation in ASDoc format is included in the download and is also online here: AS3 WordPress Documentation

Usage

The use of this library is intended to be straightforward – there are three basic steps:

Create a WPService
Add event listeners to listen for server results
Make a method call using one of the service method groups

1. Create a WPService

var service:WPService = new WPService(myBlogUrl, myUserName, myPassword);

2. Add event listeners

service.addEventListener(WPServiceEvent.GET_RECENT_POSTS,getRecentPostsHandler);

3. Make a service call using one of the service method groups.

service.posts.getRecentPosts();

The WPService class has methodgroups for making calls relating to blogs, posts, pages, categories, tags, comments and authors, eg: service.posts.getRecentPosts(); will make a call to wp.getRecentPosts using the blogUrl, username and password you used to initialize the service.

A simple example

This class will get the 20 most recent posts from your blog and trace their details to the output window. You will need to replace URL, USER, and PASS with your correct details.


package{
   import flash.display.Sprite;
   import com.absentdesign.core.webapis.events.ServiceEvent;
   import com.absentdesign.core.webapis.wordpress.events.WPServiceEvent;
   import com.absentdesign.core.webapis.wordpress.*;

   public class Example extends Sprite{
      private var service:WPService;
      private static const URL:String = "http://path.to.your.blog/";
      private static const USER:String = "your_user_name";
      private static const PASS:String = "your_password";

      public function Example(){
         service = new WPService(URL,USER,PASS);
         service.addEventListener(WPServiceEvent.GET_RECENT_POSTS,
                                                 getRecentPostsHandler);
         service.posts.getRecentPosts(20);
      }

      protected function getRecentPostsHandler(event:ServiceEvent):void{
         traceData(event.data);
      }

      protected function traceData(data:*):void{
         if(data is WPStruct){
            trace(data.getDump())
         }
         else if(data is Array){
            for each(var struct:WPStruct in data){
               trace(struct.getDump())
            }
         }
         else{
            trace(struct);
         }
      }
   }
}

This library is free to use, modify and distribute under a New BSD licence. If you do find it useful, please let me know at reuben[at]absentdesign[dot]com, or leave a comment below.

If you use the library for a commercial project (or just really like it), you may even want to consider a donation:

A caveat

There are a few things in the WordPress XML-RPC spec that were not included in the library (most notably wp.getOptions and wp.uploadFile), but these may be included in future releases. This is only version 1, and it has only been tested by me so far. Some things are bound to go wrong – if you have a problem with the library then please let me know!

Changelog

v1.01 : updated Categories.as to include setPostCategories method (mt.setPostCategories).

Awesome idea and what i needed right now:)

Does it work with flash ide? I tested it and got several errors

For example: 1017: The definition of base class AbstractService was not found.
Reuben said at 6:37 am on April 4th, 2009:
Sorry David, it doesn’t work with the Flash IDE as Ak33m’s XML-RPC Lib requires a few of the Flex SDK compiled classes – unfortunately I couldn’t get around this.
David said at 9:54 am on April 4th, 2009:
too bad:(

ok thx
Florian said at 8:27 pm on April 10th, 2009:
Great! Thanks a lot. This is really good work.
Florian said at 8:14 am on April 13th, 2009:
Me again … Works great so far.

Just want to ask if it’s possible to post into a specific category (service.posts.newPost)? I can grab the existing categories, but seems like there’s no “categories” property in the Post Class.

Thanks! Florian
Reuben said at 9:21 am on April 13th, 2009:
Hi Florian

Thanks for picking that up – I actually forgot to add the mt.setPostCategories method to the Categories class.

There is no “categories” property in any of the Post calls in XML-RPC wp but once I’ve fixed the Categories class you will be able to call service.categories.setPostCategories(postId:int,categories:Array) to update the categories on a particular post.

I’ll add the setCategories method upload a new version later today.
Reuben said at 8:29 pm on April 14th, 2009:
I’ve updated the library to include the categories.setPostCategories method now – let me know how you go.
Florian said at 7:59 am on April 17th, 2009:
Thanks for the update, works perfect

By the way: I just want to mention that here’s a fix for the classes of the XML-RPC library in order to use it with Flex 3 + 4: http://ak33m.com/?p=50
Florian said at 5:04 am on April 23rd, 2009:
Hi Reuben, is there a possibility to check if the connection to a blog could be established? Is there an error event if there’s problem (for instance a wrong url, username or password).

Thanks, Florian
Shisang Lu said at 7:17 pm on April 28th, 2009:
Thank you very much! I will use it to build a flex blog site based on WordPress.
Tizzle said at 3:21 am on May 2nd, 2009:
Hi Reuben, this is awesome.

I haven’t tried it out yet, but i wonder if it is possible to do a search from flex?

Thanks!
Reuben said at 11:29 am on May 2nd, 2009:
@ Florian – sorry, the WP XML-RPC spec is quite limited and does not return specific errors – I’ll look into implementing better error handling on the flash side in a future release.

@ Shisang Lu – thanks!

@ Tizzle – As far as I can see, the WP XML-RPC spec does not have any search functionality built in – the only way I can think to do it would be to call posts.getRecentPosts(9999) and then perform a search on the Flex side.
charlie said at 11:17 am on May 14th, 2009:
Thanks for all the heavy lifting! I’ll check it out as well, sounds really promising…
Reuben said at 10:59 am on May 15th, 2009:
@ charlie – no problem – if you do use it for something interesting let me know, I’d love to see what people use it for…
Roma said at 9:16 am on May 20th, 2009:
Great work you’ve done!

But I’m ambarassed with these strings: private static const URL:String = “http://path.to.your.blog/”; private static const USER:String = “your_user_name”; private static const PASS:String = “your_password”;

So anybody can decompile my flash and mess with my password? It’s not good. Is there any way to make it more secure? The best way is to make me enter login/password any time flash-app strts working. And then sending this info encrypted.
Reuben said at 9:49 am on May 20th, 2009:
@Roma – thanks.

I just set these strings up as a simple example to get you up and running – you don’t have to hard-code the password by any means – there is no reason you couldn’t build a different interface that would create the WPService and login once the user had entered their details.

I’m not sure how you’d go about sending the info encrypted though – the WP XML-RPC interface (as far as I know) isn’t set up to handle encrypted data.
brian said at 6:41 am on June 5th, 2009:
hi, i’m pretty excited to have found this, but i have some questions.

so, it seems like if you want to retrieve posts, you can only get a particular post by its ID or get a number of recent posts ? is there no way to pass in parameters, such as category ?

thanks
thomas said at 1:09 am on July 12th, 2009:
Thanks for this work ! very cool tool, and realy pretty code !

But i have a problem with the new method : setPostCategories, i call it just after created a post, but it does’nt work. The event is fired WPServiceEvent.SET_POST_CATEGORIES

and “event.data” return “true” …

I did’nt know why ?

any ideas ?

thanks again.
Reuben said at 7:21 am on July 12th, 2009:
@ brian – thanks – unfortunately, no, you can’t get an array of posts with additional params – the WP XML-RPC interface only has the two calls (by ID or by number) – it is quite limited.

@ thomas – This is actually the correct response based on the mt.setPostCategories call (which Word Press uses) – It is my documentation that is wrong – see here: http://www.sixapart.com/developers/xmlrpc/movable_type_api/mtsetpostcategories.html

When you call setPostCategories, you will have to call getPost again to check that your categories have been updated correctly, the categories are not returned in the SET_POST_CATEGORIES event – sorry about the confusion.
thomas said at 6:34 am on July 13th, 2009:
ok But my categories are no updated correctly and i don’t know why

i try it :

var cats : Array = new Array();

for ( var i in wpcategories.selectedItems ) { var a : Object = new Object(); a.categoryId = int( (wpcategories.selectedItems[i] as Category).categoryId ); cats.push( a ) ; }

_wpservice.categories.setPostCategories( postId, cats );

I check postId and categoryId and there seem good, I check on my blog and the categoryId exists …

I’m lost

Do you have any example ?

Thanks in advance.
thomas said at 9:06 am on July 13th, 2009:
Find the solution, we should pass a Category Object to setPostCategories ( postId, Category)

was hard,

thanks again for this great lib !

nigelg said at 1:55 am on July 29th, 2009:
Great work, very useful!

I’m having a bit of difficulty using getComments. The params I pass seem to be ignored and the last 10 messages for the blog are always returned regardless of what is passed in.

In the example below there are more than 10 comments to post#0 but only the last 10 comments (some of which belong to other posts) get returned.

var serv:WPService = new WPService(Url, User, Pass); serv.addEventListener(WPServiceEvent.GET_COMMENTS, gotNewWPComments); serv.comments.getComments(0,”",0,999999);
nigelg said at 8:58 pm on July 29th, 2009:
Update to the last post…

After debugging and reading http://code.google.com/p/as3-rpclib/issues/detail?id=5 (which isn’t quite right), I’ve found out where the problem was.

A Struct (which is optional for getComments and other wp methods – http://codex.wordpress.org/XML-RPC/wp.getComments) is not created properly.

THE FIX: Replace the last ‘else if’ block from the method encodeObject inside XMLRPCSerializer with this…

else if (tobject is IXMLRPCStruct) { //txmllist = encodeStruct(tobject.getPropertyData()); – removed as struct was not being created properly. N.Gossage 29/Jul/09 txmllist = encodeStruct(tobject); }
nigelg said at 12:06 am on July 30th, 2009:
Another bug fix for getComments. Inside Comments.as, the method getComments has this line…

struct.postId = postId;

it should be…

struct.post_id = postId;

This change should also be applicable to other methods where the struct contains a post_id.

Am I doing something wrong? I tried the library with Flex SDK 2, 3 and 4 and I always get a 1017 error: The definition of base class AbstractService was not found.
littlebuddha said at 10:41 am on August 13th, 2009:
Hi,

do u have a version for Flex SDK 3.2, 3.4, 4 ???

I hava a error by 3.2: override public function setCredentials (username:String,password:String):void { this._gateway.setCredentials(username,password); }
```
    override public function setRemoteCredentials (username:String,password:String):void
    {
        this._gateway.setRemoteCredentials(username,password);
    }
```
in this both lines is a error what not allowed in 3.2 but i don’t know why…

best regards

very nice work!!!!!!!
Sean said at 4:26 am on August 19th, 2009:
Great Work!

I am hoping to use this library for a WordPress MU/Buddypress installation. Does this framework support WordPress MU and Buddypress?
robojiannis said at 2:03 am on September 11th, 2009:
ok I got it to work; I saw a comment about getting errors if something goes wrong. My solution is putting at the constructor of the com.absentdesign.core.webapis.events.ServiceEvent Class the following:

if (data.faultString != undefined){ trace(“FAULT STRING”); trace(data.faultString); }

I am trying now to write an ERROR if the xmlrpc.php URL is wrong.

well done! always wanted to do a wordpress blog in flash. managed to compile it and connect properly. was getting a run-time error using Flex 3.0 SDK, although if i used Flex 3.1 – 3.4 SDK, it worked fine.

any idea what this could be? error message below as a reference.

I was wondering if there was any more news/work done on the security for:

private static const USER:String = “your_user_name”; private static const PASS:String = “your_password”;

I ask because I’d love to implement this but as someone else mentioned above, I’m not a fan of the idea of having people able to decompile the website and find that information sitting in my code.

Thanks.
nigelg said at 2:05 am on October 28th, 2009:
@Nuwan – Looking at my code I think I hit the same problem after my last change too so I added this block above my last change in the same place (the method encodeObject inside XMLRPCSerializer)

//added to enable posting new comments – N.Gossage 29/Jul/09 else if (tobject is com.absentdesign.core.webapis.wordpress.Comment) { txmllist = encodeStruct(tobject.getPropertyData()); }

@everyone – This is a fix to the comments part of the API, read my previous comments on this page to understand the context of this message.

Alistair C said at 8:32 pm on November 10th, 2009:
Hey Reuben, thanks for sharing your work, it’s really neat.

One thing I can’t figure out how to do is to access the categories of the posts returned. For example, if I want to retrieve the 20 most recent items from the ‘news’ category of my wordpress blog, I have to retrieve X amount of recent posts, then individually check the categories each one has using getPostCategories(). Each post has to have an individual http request sent which is quite slow and these must be done one-at-a-time so the app knows which request is being responded to (the post id is not returned with the categories).

When my list of recent posts is returned the posts do not have a category property.

Is there a way I can request posts of a certain category or access the category of returned posts?

I’m sure I must be missing something obvious here!

Thanks for any assistance Alistair

dirtyFlasher said at 3:56 am on March 18th, 2010:
Great bit of coding Reuben, thanks for sharing. I have one thing that I’m particularly worried by though: the username and password can quite easily be picked up using Charles or other similar software. As far as I can see within WordPress, you have to set the user that is retrieving data to be at least a editor, meaning that if someone had the know-how and wanted to screw up your wp, they’d have absolutely no problem. Hopefully I’m wrong with this and there’s a nice easy route around it?
Reuben said at 7:47 am on March 18th, 2010:
@dirtyFlasher, @randiD – I haven’t really looked at options here – you could try setting up a php file that passed the values in to the flash using a POST call, but I’m not sure if this would provide better security or not – unfortunately the WP api requires a user/pass with every call so the flash needs to know it somehow…

@everyone else – sorry I haven’t posted any bug fixes, or responses to your queries, I haven’t had any time to work on this library for months… I’ll get back on it some time soon.
dirtyFlasher said at 3:09 am on March 19th, 2010:
Following previous comment, thought I’d feed back a solution that works for us with regards to security. We’re only using WP as a CMS to feed data to our site, so instead of passing username and password with every call to XMLRPC we’re going to remove these from the calls and hard-code the username and password in the xmlrpc.php file in the WP install and remove/disable all edit and delete functions from within there. Obviously if you were going to be doing updates from Flash then you’d not want to go this route as anyone would be able to do, so you’d have to look down the route of encryption but seems like this is the easiest and safest solution for us at the moment. Hopefully that helps anyone stumbling across this blog looking to do the same thing.
