Question

I have an Action method in Foo Controller which requires parameters:

public function fooAction($one, $two) {
    $a = one;
    $b = $two;
}

And I need to forward to that method from the other method of some Boo Controller. And one of those parameters has to be by reference parameter. The only example that the manual has is this:

$result = $this->forward()->dispatch('Boo\Controller\Boo', array('action' => 'boo'));

No any additional parameters. But they write:

$params is an optional array of parameters with which to see a
RouteMatch object for purposes of this specific request.

So, I tried:

$result = $this->forward()->dispatch('Boo\Controller\Boo', array(
                                                      'action' => 'boo',
                                                      'one' => &$one,
                                                      'two' => $two,
                                                 ));

But it doesn’t work.

Is there any way to pass additional parameters to forward controller?

UPD:

These do not work too:

$result = $this->forward()->dispatch('Boo\Controller\Boo', array(
                                                      'action' => 'boo',
                                                      'params' => array(
                                                          'one' => &$one,
                                                          'two' => $two,
                                                     )));


$result = $this->forward()->dispatch('Boo\Controller\Boo', array(
                                                      'action' => 'boo',
                                                      'options' => array(
                                                          'one' => &$one,
                                                          'two' => $two,
                                                     )));

UPD 2:

I still can’t get the functionality I want (to pass parameters with the forward plugin) but I found other solutions. Before calling the forward plugin I set the variables to the Request object and after the forward I get them from the Request in my boo Action of my Boo\Controller\BooController:

// in Foo::fooAction
$this->getRequest()->one = &$one;
$this->getRequest()->two = $two;
$result = $this->forward()->dispatch('Boo\Controller\Boo', array('action' => 'boo'));

// in Boo::booAction
$a = $this->getRequest()->one;
$b = $this->getRequest()->two;

Stupid solution, it will not work with Ajax requests. Still interested how to pass parameters with the forward plugin. OR MAYBE how to get them in the booAction. Because there in no anything in the Request if I pass them with the forward.

UPD 3 and Final:

I finally found where they’ve decided to hide parameters I pass with the forward plugin. They put them in the RouteMatch object.

– Tryyyy to guess where we’ve hidden your params… Oh yeeah, they are in the RouteMatch, of course they are there, didn’t you think smth else?

And NO ANY info in the forward plugin section of the manual!

To get params, I have to do this in my BooController::booAction:

$param = $this->getEvent()->getRouteMatch()->getParam('nameOfParam');

Answer 1

You can create a container class and use it in both controllers

in module.conf

public function getServiceConfig()
{
    return array(
        'invokables' => array(
            'my_handy_container'        => 'path\container_class_name',
        )
    );
}

Create a getter in both controllers:

public function getMyHandyContainer()
{
    if (!$this->myHandyContainer) {
        $this->myHandyContainer = $this->getServiceLocator()->get('my_handy_container');
    }
    return $this->myHandyContainer;
}

And call it using:

$myContainer = $this->getMyHandyContainer()->myHandyContainer;
$myContainer->foo = 5; // set something

ZF2 way to pass vars using forward

In the passing method do:

return $this->forward()->dispatch('controller_name', [
    'action' => 'whatever',
    'varname' => $value,
    'varname2' => $value2
]);

In the invoked controller method, do:

$param2 = $this->params()->fromRoute('varname2',false);
