build a new function as afterSave() Yii

Question

I am building a shoping cart in Yii. Now I want to buid a function with name is afterCharged() the same as afterSave(). So how to can do it? Thank you in advance

Answer 1

As Michiel said you should use an event in your method

function charge(){ 
    //Perform charge related actions
    $this->onCharge(new CEvent($this));
    //... maybe some code over here after raising the event
}

public function onCharge($event){
    $this->raiseEvent('onCharge', $event);
}

Now you have to catch the raised event. So in this component you'll declare which class and which mehod need to catch it (for example in the init method)

//OtherClass need to catch the the charge event
$callback = array(new OtherClass,'afterCharge')
$component->onCharge = $callback;

So the method afterCharge of OtherClass will be called when charge() is executed.

By the way, the method afterCharge must have the following signature

function afterCharge($event) {
}
