Create class instance from variable in Zend Framework

Question

i have class Plugin_Magazine extends Zend_Controller_Action

in some views i need to call static function test() from it.

in view i do folowing:

$class_name = 'Plugin_'.$plugin;
$class_name::test();

as a result i have

Catchable fatal error: Argument 1 passed to Zend_Controller_Action::__construct() must be an instance of Zend_Controller_Request_Abstract, none given

but, if i create class Plugin_Magazine w\o extends all works fine.

question is: can i somehow do what i need or just forget about inheritance?

First question is: why is a call to a static method resulting in a call to the constructor? — Rijk

problem solved with call_user_func(array($controller_name, 'test')) — aloneibreak

You need to pass a Request object to the constructor of the Action class

At somepint your doing this:

 $pm = new Plugin_Magazine();

But you need to pass the request object:

 $pm = new Plugin_Magazine($this->getRequest());

As for this call:

$class_name = 'Plugin_'.$plugin;
$class_name::test();

Why do you need a static function in an Action? This doesn't seem right, if it's reusable logic that exists in an Action that it should be moved elsewhere to where it can be used more easily, like into a Model.

actually static or public will be test() doesn't matters. tried to do $plugin = new Plugin_Magazines($this->getRequest()); Plugin by name 'GetRequest' was not found in the registry
