FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

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 PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • 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.
Please rate this library. Is it a good library?

Informations about the package presenters

** Installation

+BEGIN_SRC sh

composer require popcorn4dinner/presenters

+END_SRC

** Usage The idea behind presenters is to separate the presentation logic from your domain models. As a side effect you also only expose only needed functions and therefore the smallest possible interface to the render process.

*** Example

**** Simple user and Presenter class

+BEGIN_SRC php

class SimpleUser { private $firstName = "Florian"; private $lastName = "Thylman"; private $age = 13;

public function getFirstName()
{
    return $this->firstName;
}

public function getLastName()
{
    return $this->lastName;
}

public function getAge()
{
    return $this->age;
}

public function setAge($newAge)
{
    $this->age = $newAge;
}

}

+END_SRC

+BEGIN_SRC php

class ExamplePresenter extends AbstractPresenter {

protected const DELEGATED_METHODS = ['getFirstName', 'getLastName'];

public function getFullName()
{
    return $this->getFirstName() . ' ' . $this->getLastName();
}

public function getAge()
{
    return $this->original->getAge() . ' years';
}

}

+END_SRC

**** Example usage Controller:

+BEGIN_SRC php

class UserController { public function view(Request $request, FindUserHandler $handler, \Twig_Environment $twig) { $command = $this->commandPopulator->populate(new FindUser(), $request); $user = $handler->execute($command, $user);

  $response =  new Response(
  $twig->render(
    'users/view.twig',
    [
      'user' => new UserPresenter($user)
    ]
  )
  );
  return $response;
}

}

+END_SRC

View:

+BEGIN_SRC twig

Name: {% $user->getFullName() %} // Florian Tylman Age: {% $user->getAge() %} // 13
