Quicktips: Finding all the actions in your controller

Published: on 11/9/08 | Comments (0)

Hi All,

Thought I'd share a quick tip today for how to automatically detect all the action names within a given controller.

This follows on from my last quicktip, describing how to detect all the controllers in your application and is usefull from witin navigation code or admin back ends.

$actions = get_class_methods($this);

This returns an array where each element is the name of a method within the current controller.

Filtering your results

You can make this more usefull by filtering the actions, for example to remove all the inherited actions from app_controller use:

$ignore = get_class_methods('Controller');
foreach($actions as $key=>$action){
            if(in_array($action, $ignore)){
                unset($actions[$key]);
                continue;
            }
}

and this can be extended further to remove any private or protected methods with:

$ignore = get_class_methods('Controller');
foreach($actions as $key=>$action){
            if(in_array($action, $ignore)){
                unset($actions[$key]);
                continue;
            }
            if(strpos($action, '_', 0) === 0){
                unset($actions[$key]);
                continue;
            }
}

That's it for today, hope some of you find this helpfull, see you all soon.
