Flextrine 0.7 released – now with ZendAMF!

After much soul searching I eventually decided to put in the time to convert Flextrine from using AMFPHP to ZendAMF.  There were a few reasons I decided to make this move, but eventually it boiled down to the fact that quite a few people had asked me to do so.  In retrospect it was certainly the right thing to do – ZendAMF has the green light from Adobe, its licence is LGPL instead of GPL and the cleaner code base means that the changes Flextrine requires can be implemented as overridden classes instead of having to modify the ZendAMF core.  This particularly is great news because it means that you can use Flextrine directly with the standard Zend framework installation, whereas previously you could only use the version of AMFPHP bundled with Flextrine.

Functionally speaking things remain exactly the same, and we continue to approach our stable release alongside Doctrine 2.

The new version of Flextrine can be downloaded from www.flextrine.com.  Note that if you are upgrading from a previous version of Flextrine you will need to regenerate your AS3 entities.

After numerous requests I have finally sat myself down to write a basic tutorial for using Flextrine in a practical and simple Flex application.

What is Flextrine?

In a sentence, Flextrine is an open-source solution for reading and writing AS3 objects to and from a remote database.  Flextrine doesn’t really do anything that you couldn’t do by hand using PHP and AS3 code, but it removes most of the grunt work and standardises client-server database interactions.  All being well, database aware Flex applications coded using Flextrine are shorter, more readable and more maintainable.

Documentation for Flextrine is available in its Google Code wiki and its definitely worth having a skim through before beginning the tutorial.

What shall we build?

In this tutorial we are going to demonstrate some of Flextrine’s functionality by building a simple online contacts manager.  The application will allow us to create, edit and delete contacts, each of which simply have names and telephone numbers.  In order to demonstrate some of Flextrine’s associations we will also allow the user to put contacts into groups.

Note that the purpose of this tutorial is to demonstrate Flextrine rather than Flex, so we won’t be using any frameworks (apart from Flex itself) and where there is a choice between an elegant programming solution and just keeping it simple we’ll be going for the simpler option 🙂


To run through this tutorial you will need the following:

  • Flex SDK 4 (free from Adobe)
  • A nice Flex IDE – I personally use the wonderful FlashDevelop, but Flash Builder 4 will do just as well
  • A web server running PHP 5.3+ and MySQL (WAMP for Windows and MAMP for OSX are good choices)
  • Download the complete source code for the tutorial and save yourself tedious typing!  This does not include the Flextrine AS3 code so you will need to add the source code or SWC to your classpath manually before compiling.

Lets begin by installing Flextrine and its dependencies.

Getting the Class of an object in AS3

A quick and useful titbit: in order to get the class of an object use the following code:

   1: static function getClass(obj:Object):Class {
   2:     return Class(getDefinitionByName(getQualifiedClassName(obj)));
   3: }

This is great for checking the type of an object.  For example, if you have an object myObj1 and you want to confirm that it is of the same type as myObj2 you can write:

   1: if (myObj1 is getClass(myObj2)) {
   2:     trace("These objects are of the same class!");
   3: }

Nike Team Kit Builder

As this was such a large project I couldn’t fit all the bits in my portfolio page, so here is a list of technologies and collaborations along with a selection of pretty screenshots.

The majority of work was performed off-site, and if you would like to see it in action you can go and create your very own team kit on the first floor of Niketown, Oxford Street, London.

UPDATE: This project has at last been modified into a web-friendly version and put online, so you can now see many of the original features and create your custom kit on Nike’s site at http://www.nike.com/nikeos/p/nikefootball/en_US/kitbuilder
