Hi guys!

Finally back after a long time. I have been really busy at work.  In one of the projects, i had to get list of modules plus controllers and their respective actions for ACL configuration purposes .. I implemented the said task using action helper and controller plugin in Zend Framework. I am listing the Action helper code here. Also, when done with ACL, i will post that code here as well …

Before getting started, i am going to assume that you have configured Zend Framework installation on your local machine and setup your application through a virtual host.

First, open the Bootstrap.php in your application directory and put the following code:

<?php

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{

    protected function _initAutoLoad(){
        $autoLoader = Zend_Loader_Autoloader::getInstance();
        $autoLoader->registerNamespace('Application_');

        return $autoLoader;
    }

    protected function _initActionHelpers() {
        Zend_Controller_Action_HelperBroker::addHelper(new Application_Action_Helper_AssetsList());
    }

Now do the following:

1. Create a folder called Application in your site’s library folder.
2. Then create sub-folder called Actionin the Applicationfolder.
3. Again create a sub-folder called Helperin the Actionfolder.
4. Now a create a file called AssetsList.phpin the plugin folder.

In the AssetsList.php folder, write the following code:

<?php
class Application_Action_Helper_AssetsList extends Zend_Controller_Action_Helper_Abstract {

    public function  direct() {
    }

    public function getList() {
        $module_dir = $this->getFrontController()->getControllerDirectory();
        $resources = array();

        foreach($module_dir as $dir=>$dirpath) {
            $diritem = new DirectoryIterator($dirpath);
            foreach($diritem as $item) {
                if($item->isFile()) {
                    if(strstr($item->getFilename(),'Controller.php')!=FALSE) {
                        include_once $dirpath.'/'.$item->getFilename();
                    }
                }
            }

            foreach(get_declared_classes() as $class){
                if(is_subclass_of($class, 'Zend_Controller_Action')) {
                    $functions = array();

                    foreach(get_class_methods($class) as $method) {
                        if(strstr($method, 'Action')!=false) {
                            array_push($functions,substr($method,0,strpos($method,"Action")));
                        }
                    }
                    $c = strtolower(substr($class,0,strpos($class,"Controller")));
                    $resources[$dir][$c] = $functions;
                }
            }
        }
        return $resources;
    }
}

To get the list, simply put the following line in any controller action:

$resources = $this->_helper->AssetsList->getList();

Hopefully, this helps out everyone. I will post the dynamic ACL plugin code in coming days when i am finished with it.
