I am wondering here… how can one create an application-wide filter in Yii?
Since the default CController->filter() gets overridden, then the only decent way I could think of, was implementing the filter method of the top-level controller and then calling parent::filters() in every individual controller along with array_merge.
Is there a better way to do something like this? I simply need to invoke some site-specific code before any action executes but the controller must already be resolved, created and accessible, so the ‘onBeginRequest’ event does not seem to suit the occasion.
I already do derive my controllers from a subclass of CController. It’s the default option when using the yiic tool.
However, I’d rather not write my own implementation of CController->run() because if the official Yii framework changes in that respect, I’d be stuck. Yii has a good core feature to counter situations like that - events. They allow altering the functionality of a component without changing it’s code. Unfortunately the default implementation of CController raises exactly 0 events and right now I see no forward-compatible way to improve the behavior of CController on my own.
