README
So you have those scenarios where a bit of logic needs to be performed before some data (likely from your entity) is displayed from the view.
- Should that logic be hard-coded into the view? No.
- Should we instead store the logic in the model? No again!
Instead, leverage view presenters. That's what they're for! This package provides one such implementation.
Installation
Run the Composer command to install the latest stable version:
composer require frostealth/php-presenter @stable
Usage
The first step is to store your presenters somewhere - anywhere. These will be simple objects that do nothing more than format data, as required.
Here's an example of a presenter.
namespace app\presenters; use frostealth\presenter\Presenter; /** * Class ConcreteEntityPresenter * * @property-read string $fullName * @property-read string $birthDate */ class ConcreteModelPresenter extends Presenter { /** * @return string */ public function getFullName() { return implode(' ', [$this->firstName, $this->lastName]); } /** * @return string */ public function getBirthDate() { return date('y.M.d', $this->entity->birthDate); } }
Here's an example of an presentable model.
namespace app\models; use app\presenters\ConcreteModelPresenter; use frostealth\presenter\interfaces\PresentableInterface; class ConcreteModel implements PresentableInterface { /** @var string */ public $firstName; /** @var string */ public $lastName; /** @var string */ public $birthDate; /** @var ConcreteModelPresenter */ protected $presenter; /** * @return ConcreteModelPresenter */ public function presenter() { if ($this->presenter === null) { $this->presenter = new ConcreteModelPresenter($this); } return $this->presenter; } }
Now, within your view, you can do:
<dl> <dt>Name</dt> <dd><?= $model->presenter()->fullName ?></dd> <dt>Birth Date</dt> <dd><?= $model->presenter()->birthDate ?></dd> </dl>
