I posted a CakePHP component implementation of PHPIDS today. It includes the latest PHPIDS version (0.6.4).
What I like about the component implementation is that you set the actions you want to monitor when you import the component in the corresponding controllers or your main app_controller.php. Something like this:
var $components=array(‘Cakephpids’=>array( ‘protectedActions’=>array(‘login’,’add’,’register’,’display’)));
Putting this in your main app_controller will run the IDS only when the actions login,register and add are executed.
