I have published a yii module that makes it very easy to communicate with Flash/Flex applications.
You can download it on Github.
The module is standalone, Zend AMF is included, if it is outdated you can update it following the instructions.
Instructions how to use it:
The module amfGateway permits anyone to have a very easily configurable RPC with Flash and Flex.
[size="4"]Setting up and usage[/size]
To use the module follow these steps:
Make sure you have a modules folder in your protected folder of your Yii application. If not create it. Inside the modules directory copy the modules/amfGateway folder provided by this repository. Now you have to enable the module in your Yii application. Open the file protected/config/main.php and in the modules section add
'modules' => array( 'amfGateway' => array( 'servicesDirAlias' => 'application.services.amf', 'production' => TRUE, ) ),
Now your gateway for AMF is found at http://yiiurl?r=amfGateway. The classes and methods that are exposed to Flash/Flex are found in the application.services.amf directory which essentially is protected/services/amf. You can find an example in the services/amf/TestService.php file that is provided.
If you have any problem while setting it up and you want to see more error messages, change the ‘production’ parameter seen above to FALSE.
Zend AMF is located in the vendors/ folder inside the module folder. If it is not up-to-date can be easily updated by downloading Zend AMF from http://framework.zend.com/download/amf and then extracting the Zend folder directly into the Zend folder.
There is a flash example in the folder flash_demo. To make it work make sure you setup the module as described above. Then copy the services folder in the yii protected/ folder. After that go to amftest.as and change the following line
var gateway:String = "http://amftestapp/index.php?r=amfGateway";
to make sure it points to the right URL according to your computer. You can now run amftest.fla and see in the console the results.
