Description
The core feature of this “plugin” is the ability to set parameters for controller methods.
Primarily to pass the value of a variable of a route directly to the method at the dispatch event as an argument.
The new AbstractInjectorController
must be used for this usage.
In addition, with the new dispatcher you can also do without the “Action” postfix for these methods.
Requirements
- PHP 8.1 or above
- Laminas MVC 3.7.0 or above
Installation
Use composer to install the package:
composer require nubox/laminas-controller-injector
Activate Plugin in our Laminas Application
return [ // Retrieve list of modules used in this application. 'modules' => [ ..., Laminas\Mvc\Injector\Module::class, // or 'Laminas\Mvc\Injector' ], ... ];
Usage
Suppose you have a controller that looks like this:
class MyController extends AbstractInjectorController { public function myMethod(string $param) { // ... } }
You can map routes to this controller method using the format controller::method
and
pass parameters from the routes directly into the method:
return [ 'router' => [ 'routes' => [ 'my-route' => [ 'type' => Laminas\Router\Http\Segment::class, 'options' => [ 'route' => '/my-route/:param', 'defaults' => [ 'controller' => MyController::class, 'action' => 'myMethod' ] ] ] ] ], ];
In the example above, the :param
placeholder in the route gets passed directly as the $param
argument
to myMethod()
.
AbstractInjectorController
The provided \Laminas\Mvc\Injector\Controller\AbstractInjectorController
is required as Controller extension.
It matches the given parameter values into the requested action. The same variable name is required.
As soon as the AbstractInjectorController
is used, in addition to the route parameters, objects from the
ServiceManager
are also injected into the corresponding controller method - regardless of the route.
This reduces the processes necessary to access a service from the ServiceManager.
The respective request can also be injected as a complete request object.
class MyController extends AbstractInjectorController { public function serviceParameter(DemoService $demoService): Response { $response = new Response(); $response->setContent($demoService->getValue()); return $response; } }
Available ArgumentResolver -> (configurable controller_argument_resolver
)
Every argument of a controller method is analyzed and can be determined by the activated ArgumentResolver. The following ArgumentResolvers are activated by default. However, additional ArgumentResolvers can also be added.
Activated by default:
- IntegerArgumentResolver - inject a
int
, parsed from Route parameters (int
required) - StringArgumentResolver - inject a
string
, parsed from Route parameters (no typehint orstring
required) - RequestArgumentResolver - inject the responding
Request
object into the method (Request
required) - ServiceArgumentResolver - inject an
object
from the container (ServiceManager) (explicit object Typehint required)
return [ /** * each resolver need to implement ArgumentResolverInterface:class */ 'controller_argument_resolver' => [ StringArgumentResolver::class, IntegerArgumentResolver::class, RequestArgumentResolver::class, ServiceArgumentResolver::class, ], ];
Normally you need a corresponding type hint to determine the correct ArgumentResolver.
In the event that no suitable type can be found, you can use the MarkUp interface NonTypeArgumentResolverInterface
for your own ArgumentResolver. this would then also be “queried” in such a case.
Suggestion
Use nubox/laminas-router-attributes for reduce configuration overhead with symfony route attributes.
class MyController extends AbstractInjectorController { #[Route(path: 'calc-optional/{operand1}/{operand2?100}', name: 'calc-optional-route')] public function calculateWithRouteDefault(int $operand1, int $operand2 = 100): Response { $response = new Response(); $response->setContent($operand1 * $operand2); return $response; } #[Route(path: 'default', name: 'default-route')] public function somedefaults(Request $request, string $default = 'defaults'): Response { $response = new Response(); $response->setContent($request->getUri()->getPath() . ' - ' . $default); return $response; } }
