FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package laminas-controller-injector
Laminas Controller Injector
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
Usage
Suppose you have a controller that looks like this:
You can map routes to this controller method using the format controller::method and
pass parameters from the routes directly into the method:
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.
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 (intrequired) - StringArgumentResolver - inject a
string, parsed from Route parameters (no typehint orstringrequired) - RequestArgumentResolver - inject the responding
Requestobject into the method (Requestrequired) - ServiceArgumentResolver - inject an
objectfrom the container (ServiceManager) (explicit object Typehint required)
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.
