A clean, reusable solution for separating presentation logic from models and views in PHP applications.

✨ Introduction

When models or views become bloated with formatting and derived data logic, View Presenters offer a way to offload that responsibility into dedicated presenter classes. This improves separation of concerns, testability, and reusability.

📦 Installation

Install via Composer:

composer require andrewdyer/view-presenters

🚀 Getting Started

1️⃣ Define a Presenter

Create a presenter class that extends Presenter:

<?php

namespace App\Presenters;

use App\Models\User;
use Anddye\ViewPresenters\Presenter;

class UserPresenter extends Presenter
{
    public function __construct(readonly private User $user) {}

    public function defaultAttributes(): array
    {
        return [
            'id' => $this->user->getId(),
            'forename' => $this->user->getForename(),
            'surname' => $this->user->getSurname(),
        ];
    }

    public function name(): string
    {
        return $this->user->getForename() . ' ' . $this->user->getSurname();
    }
}

2️⃣ Attach Presenter to Model

Use the HasPresenters trait in your model and define available presenters:

<?php

namespace App\Models;

use App\Presenters\UserPresenter;
use Anddye\ViewPresenters\HasPresenters;

class User {
    use HasPresenters;

    protected int $id;
    protected string $forename;
    protected string $surname;
    protected array $presenters = [
        'default' => UserPresenter::class,
    ];

    public function getId(): int
    {
        return $this->id;
    }

    public function getForename(): string
    {
        return $this->forename;
    }

    public function getSurname(): string
    {
        return $this->surname;
    }
}

📖 Usage

Access presenter attributes via the present() method:

$user = new User();
$user->setId(1);
$user->setForename('John');
$user->setSurname('Doe');

echo $user->present()->name; // "John Doe"
