Object-oriented presentation logic.

Getting Started

Run the following to add Presenter to your project’s composer.json. See Packagist for specific versions.

composer require deefour/presenter

>=PHP5.5.0 is required.

The Presenter Factory

A factory class is available to resolve the FQCN for or instantiate an instance of a presenter class associated with the passed presentable object.

use Deefour\Presenter\Factory;

(new Factory)->resolve(new Article);          //=> 'ArticlePresenter'
(new Factory)->make(new Article);             //=> 'ArticlePresenter'
(new Factory)->makeOrFail(new Article);       //=> 'ArticlePresenter'
(new Factory)->makeOrFail(new InvalidObject); //=> throws 'NotPresentableException'

Preparing Models for Presentation

Given an Article object

namespace App;

class Article
    public $published = true;

    public $title = 'Governor Mike Taylor Runs for Second Term';

    public function isDraft()
        return ! $this->published;

The factory is unwilling to attempt presenter instantiaion for classes that do not implement Deefour\Presenter\Contracts\Presentable. A Deefour\Presenter\ProducesPresenters trait is available to satisfy the interface.

namespace App;

use Deefour\Presenter\Contracts\Presentable;
use Deefour\Presenter\ProducesPresenters;

class Article implements Presentable
    use ProducesPresenters;

    // ...

By default, the factory will resolve 'App\ArticlePresenter'. A resolve method can be added to the class to provide custom logic.

namespace App;

use Deefour\Presenter\Contracts\Presentable;
use Deefour\Presenter\ProducesPresenters;

class Article implements Presentable
    use ProducesPresenters;

    public function resolve()
        return $this->published ? 'App\\PublishedArticlePresenter' : 'App\\ArticlePresenter';

Note: When using this package with deefour/authorizer or deefour/producer, care must be taken when overriding the resolve() method to account for policies, scopes, and other classes that may be resolved through the production factory in deefour/producer.


As for the ArticlePresenter itself, a bare implementation could be

namespace App\Presenters;

use Deefour\Presenter\Presenter;

class ArticlePresenter extends Presenter
    public function isDraft()
        return $this->_model->isDraft() ? 'Yes' : 'No';


A quick overview of the API available.

use Deefour\Producer\Factory;

$presenter = (new Factory)->make(new Article, 'presenter'); //=> ArticlePolicy

$presenter->_model; //=> Article

$presenter->_model->isDraft(); //=> false
$presenter->isDraft(); //=> 'No'
$presenter->is_draft; //=> 'No'

$presenter->_model()->published; //=> true
$presenter->published; //=> true

A few things to notice:

  • The underlying object decorated by the presenter can be accessed via the $model property or model() method.
  • Any property or method publicly accessible on the underlying object can also be accessed directly through the presenter.
  • Any publicly accessible, camel-cased method on the presenter or underlying model can be accessed via snake-cased property access.

Automatic Presenter Resolution

If a property or method is resolved through the __get() or __call() methods on the presenter, an attempt will be made to resolve and wrap the return value in a related presenter.

namespace App;

use Illuminate\Support\Collection;

class Article
    public function category()
        return new Category;

    public function tags()
        $collection = Collection;

        $collection->push(new Tag);
        $collection->push(new Tag);
        $collection->push(new Tag);

        return $collection;

Given the existence of ArticlePresenter, CategoryPresenter, and TagPresenter, the following will be returned

use Deefour\Presenter\Factory;

$presenter = (new Factory)->make(new Article, 'presenter'); //=> ArticlePresenter

$presenter->category; //=> CategoryPresenter
$presenter->tags->first(); //=> TagPresenter

Note: The collection resolution works by looking for an instance of IteratorAggregate. The iterator is used to loop through the collection and generate presenters for each item. An attempt is then made to instantiate a new instance of the original object implementing IteratorAggregate. That is the return value.

If you want access to the raw association, simply request it from the underlying object.

$presenter->_model->tags()->first(); //=> Tag

Helper Methods

A global present() function can be made available by including the helpers.php file in your project’s composer.json. Presenter doesn’t autoload this file, giving you the choice whether or not to ‘pollute’ the global environment with this function.

"autoload": {
  "psr-4": {
  "files": [

In a view, the following could be done

present($article)->is_draft; //=> 'No'



1.0.0 - October 7, 2015

  • Release 1.0.0.

0.8.0 - August 8, 2015

  • Compat changes for updates to deefour/producer.
  • New Factory class is available to prevent the need to interact directly with the factory in deefour/producer.
  • Abstracted presenter resolution out to new deefour/producer.
  • Removed the Laravel service provider and facade. The 'producer' service in deefour/producer should be used instead.

0.6.2 - June 5, 2015

  • Now following PSR-2.

0.6.0 - May 24, 2015

  • Removed model() method on base presenter.
  • Renamed $model property to $_model to avoid conflicts with an actual model attribute with the name 'model'.
  • Presenters now only provide property access to public properties on the presenter.
  • Prefixed API methods/properties with _ on the base presenter to further avoid conflicts with attribute overrides.
  • Made $_model property public.
  • Updates to code formatting.

0.5.0 - April 27, 2015

  • Snake-case to camel-case method conversions are now cached for performance
  • Exceptions are no longer thrown for missing properties/methods. See 6f33dda for an explanation.

0.4.0 - March 19, 2015

  • Rename presenter() helper to present()
  • Remove helpers.php from Composer autoload. Developers should be able to choose whether these functions are included.
  • Cleaning docblocks.
  • Type-hinting the presenter factory.
  • Renaming Presentable trait to ResolvesPresenters to avoid naming conflict with \Deefour\Presenter\Contracts\Presentable.

0.3.0 - March 16, 2015

  • Allow presenters to be explicitly requested, bypassing the model default. For example php $article = new Article; echo get_class($article->presenter()); //=> 'ArticlePresenter' echo get_class($article->presenter(FeaturedArticlePresenter::class)); //=> 'FeaturedArticlePresenter'

0.2.3 - February 27, 2015

  • Illuminate\Support\Collection instances and native PHP arrays can now be passed directly into the presenter() helper.

0.2.2 - February 20, 2015

0.2.0 - February 5, 2015

  • Fix service provider.
  • Make global presenter() work with Laravel IoC container if it’s available.
