I was wondering if it was possible to put a php script on part of a flash page. For example, when u click a button, a box appears that has the most recent posts from your forum. I have the php scipt and everything, i just need to know how i can get it to function like that. Thanks
That is beyond the scope of Flash Catalyst. You would be able to add that functionality to a Flash Catalyst project from within Flash Builder. You would need to add some ActionScript code to the project to make it work. But you could do the visual design in Flash Catalyst first before working with the code.
Take a look at the new Data Wizard in Flash Builder to assist in the connections to the PHP script. There are tutorials on tv.adobe.com on this.
