Plug-in architecture

Yii 1.1 General Discussion

Hi,

I want to implement a plug-in (hook) architecture inside my app.

I was thinking at something like




Yii::import('...');    // import plug-ins







public function myMethod()

{

    $this->raiseEvent('onBeginMyMethod', new CEvent($this));    // execute before


    ...    // method code


    $this->raiseEvent('onEndMyMethod', new CEvent($this));    // execute after

}

for every method, so I can add code before/after their execution.

What do you think about this? Is there a more elegant way?

You’re describing Aspect Oriented Programming (or AOP):

Google search for PHP AOP

Do you think using Yii Events is suitable for this?

Is there a way I could stop the execution of myMethod() after invoking the first event (from the invoked function itself)? So I can also "override" the original method by using the onBegin event and then stopping the flow.
