I'm going to use Cu3er, which is a image slideshow on my website. It's going to have simple transitions between images so my XML config file will be pretty simple. Right now, I store all the images and configuration information in DataObject and edit it through ImageDataObjectManager. I want it to save it all to the XML file that is accessed by flash object on a site, so every single time I press Save and Publish, a file would be updated.
I know one way to do: in HomePage.php(that's where my cu3er flash object is held) write a function onAfterWrite() and there take all the data from database field and through standard php functions save it to the XML file
$xmlfile = fopen($currTheme . "/cu3er/config.xml", "w");
Is this is a good way or could you recommend me a better way please?
