ZF2 Accessing routes and posts via a factory - zend-framework2

Question

I am trying to access a route and post via a form factory. The route or the post contains an ID which I need to inject into my form so that I can build a select statement.
Currently I am injecting into the form via the controller using
$this->MyForm->get('elementName')->setOptions(array('value_options' =>$myArrayOfOptions));
My goal is to keep the business logic out of the controller hence why I am keen to use the formFactory instead however I do need access to the ID in the post or route to achieve this.
My Form Factory looks like this:
<?php
namespace MyModule\Form;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use AdminLottery\InputFilter\MyFilter;
use AdminLottery\Service\MyService;
class MyFormFactory implements FactoryInterface
{
/**
* Create service
*
* #param ServiceLocatorInterface $serviceLocator
* #return mixed
*/
public function createService(
ServiceLocatorInterface $serviceLocator
)
{
//$serviceLocator is FormElementManager
$realSL = $serviceLocator->getServiceLocator();
//*** I NEED TO ACCESS THE ID / POST HERE TO SEND TO MY FORM
return new MyForm(
$realSL->get('Doctrine\ORM\EntityManager'),
$realSL->get('InputFilterManager')->get(MyFilter::class),
$realSL,
$realSL->get(MyService::class)
);
}
}
Any Ideas??

Answer 1

You can access the request instance
MyFormFactory
//...
$request = $serviceLocator->getServiceLocator()->get('Request');
$id = $request->getPost('id', false);
if ($id) $form->setOption('id', $id);
//...
Edit: This is very similar to another question I answered
Edit 2
In your factory can access the route params via the router's Zend\Mvc\Router\RouteMatch.
$request = $serviceLocator->getServiceLocator()->get('Request');
$router = $serviceLocator->getServiceLocator()->get('Router');
$match = $router->match($request); // \Zend\Mvc\Router\RouteMatch
$id = ($match) ? $match->getParam('id', false) : false;
if ($id) $form->setOption('id', $id); //....

Answer 2

For anyone looking for a reference, I thought I would add the final code I used:
Semi-final code::
$router = $realSL->get('Router');
$request = $realSL->get('Request');
$routeMatch = $router->match($request);
$matchArray = $routeMatch->getParams();
if (isset($matchArray['id'])) {
$id = (int) $matchArray['id'];
} else {
$id = 0;
}
Final code::
$realSL->get('application')->getMvcEvent()->getRouteMatch()->getParam('id', 0)

Here is an example for a controller factory, that would work in the same manner for any other factory:
namespace MyModule\Controller\Factory;
use MyModule\Controller\MyController;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class MyControllerFactory implements FactoryInterface
{
public function createService(ServiceLocatorInterface $serviceLocator)
{
/*
* #var Zend\ServiceManager\ServiceManager
*/
$realServiceLocator = $serviceLocator->getServiceLocator();
...
$router = $realServiceLocator->get('router');
$request = $realServiceLocator->get('request');
$routerMatch = $router->match($request);
...
$test1 = $routerMatch->getParams();
$test2 = $request->getQuery();
$test3 = $request->getPost();
...
return new MyController(...);
}
}
