Phraseanet PHP SDK documentation

Documentation

This documentation is out of date, please refer to the repository Phraseanet-PHP-SDK <https://github.com/alchemy-fr/Phraseanet-PHP-SDK

Introduction

Phraseanet PHP SDK is an object oriented PHP library that gives you access to the your Phraseanet ressources from your PHP application/website.

Design

This library has been strongly inspired by Doctrine ORM design and sits on top of Phraseanet API<https://docs.phraseanet.com/Devel>.

The aim is to let you build your application/mashup as if you were connected to a database.

This library provide a set of entities mapped to the logical structure of the API and a set of related repositories to fetch this entities in various ways.

This is a read only library ; current version only allow read from the API.

Installation

We rely on composer to use this library. If you do no still use composer for your project, you can start with this composer.json at the root of your project:

{
    "require": {
        "phraseanet/php-sdk": "~0.2"
    }
}

Install composer :

# Install composer
curl -s http://getcomposer.org/installer | php
# Upgrade your install
php composer.phar install

You now just have to autoload the library to use it :

<?php
require 'vendor/autoload.php';

This is a very short intro to composer. If you ever experience an issue or want to know more about composer, you will find help on their website http://getcomposer.org/.

The SDK

To use the SDK, you will need an Entity Manager. This EntityManager, provides methods to access repositories, delegating all work to an HTTP client.

Most of the time, you’ll only have to set your credentials to this client. If you want to customize it (use a configuration for your credentials, add Memcached or Redis cache...) see the dedicated section.

Phraseanet SDK client

The Client object is the heart of the SDK, it performs HTTP requests and handles authentication flow as well.

Get a Phraseanet client

For the following example we will use Guzzle Http Client Adapter which use Guzzle http://guzzlephp.org/index.html, highly customizable library.

<?php
use PhraseanetSDK\Client;
use PhraseanetSDK\HttpAdapter\Guzzle as GuzzleAdapter;

$HttpAdapter = GuzzleAdapter::create();
$HttpAdapter->setBaseUrl('http://url-to-phraseanet.net/');

$client = new Client('Your API Key', 'Your API Secret', $HttpAdapter);

Note

You have to create an application in Phraseanet to get credentials. This application will be created in “Account” => “Applications”.

Authentication

All requests performed on Phraseanet API are authenticated requests.

Phraseanet API implements OAuth2.0 http://oauth.net/2/ authentication flow, this means you MUST provide an oAuth ACCESS_TOKEN to request the API otherwise you will get a PhraseanetSDK\Exception\UnauthorizedException.

There are two ways to use the SDK in your application. Either you will use the same token for every request, either you will use a custom token using the whole oAuth2 authentication flow.

If you want to use this second way, please read the dedicated article in the recipes.

Use developer Token
<?php
$client->setAccessToken('YOUR_ACCESS_TOKEN');
Full authentication flow

If you do not want to use the developer token and prefer the oAuth2 full authentication flow, read the dedicated doc in the recipes.

Entity Manager

Once you have a client, you’ll have access to the EntityManager ; it is the central access point to Phraseanet ressources.

<?php
use PhraseanetSDK\EntityManager;

$entityManager = new EntityManager($client);

// retrieve a collection of all feeds available
$feeds = $entityManager->getRepository('Feed')->findAll();

Repositories

Repositories are access point to entities. To get a repository instance use the Entity Manager

<?php
// $em is an Entity Manager instance
$recordRepository = $em->getRepository('Record');
// return the 20 latest records
$recordRepository->find(0, 20);

$basketRepository = $em->getRepository('Basket');
// return all the active baskets of the user
$basketRepository->findAll();

Repositories methods depend of the repository. Here is the list of all available repositories and a link to the related API documentation.

Entities

Entities are ressources with identity. Their identity has a conceptual meaning inside the Phraseanet API Domain.

Since the SDK is a read only library, you will never have the need to create a new entity object but just getting them trought the API.

<?php
// $em is an Entity Manager instance
$recordRepository = $em->getRepository('Record');

// return the 20 latest records as record entities
$records = $recordRepository->find(0, 20);

foreach($records as $record) {
    // $record is an entity

    // return the title of the record
    $record->getTitle();

    // return a Subdef entity corresponding to the thumbnail
    $thumbnail = $record->getThumbnail();

    if($thumbnail) {
        $url = $thumbnail->getPermalink()->getUrl();
    }
}

Here is a complete list of all entities provided by the API and a link to their API doc.

Fetching datas from API

Now you have your entity manager, it is very easy to fetch datas. You have to get the repository type that relies on the data type you want.

Let’s say you want records, then you need the Record Repository.

Look at the Record Repository API, and see that there are three ways to retrieve records :

  • findById
  • find
  • search

Some of the repository methods will fetch one entity and some others will retrieve a collection of entities.

Fetching one element

<?php
// $em is an Entity Manager instance
$recordRepository = $em->getRepository('Record');

$databoxId = 1;
$recordId = 234;

// Fetch one record identified by its databox id ans its own id
// Return a Record Entity object
$record = recordRepository->findById($databoxId, $recordId);

Fetching a collection of elements

<?php
// $em is an Entity Manager instance
$recordRepository = $em->getRepository('Record');

$offsetStart = 1;
$perPage = 20;

// Fetch 20 records
// Return a Doctrine Array Collection object
$records = recordRepository->find($offsetStart, $perPage);

foreach($records as $record) {
    echo $record->getTitle() . "\n";
}

Lazy Loading

Whenever you have an entity instance at hand, you can traverse and use any associations of that entity to retrieve the associated objects.

<?php
// Fetch one record
$record = $recordRepository->findById(1, 87);

// Will execute a request to the api to load the record status
$status = $record->getStatus();

// performs another request to get subdefs
foreach($record->getSubdefs() as $subdef) {
    echo "Sub definition " . $subdef->getName() . " has URL " . $subdef->getPermalink()->getUrl() . "\n";
}

Note

Try to avoid lazy loading in a loop unless you have some cache implementation to reduce the number of requests.

Handling Exceptions

The PHP SDK throws 3 different types of exception :

  • PhraseanetSDK\Exception\Runtime is thrown when something went wrong most of the time you can get more informations by getting the previous exception.
  • PhraseanetSDK\Exception\UnauthorizedException which is thrown when request is not authenticated
  • PhraseanetSDK\Exception\NotFoundException which is thrown when the requested ressource can not be found

All these Exception implements \PhraseanetSDK\Exception\ExceptionInterface so you can catch any of these exceptions by catching this exception interface.

Report a bug
