PHP Models for the OpenActive Opportunity and Booking Specifications

OpenActive aims to provide model files for all classes defined in its Opportunity and Booking specifications across the PHP, Ruby, and .NET languages. This repository is intended for the PHP files; see also the Ruby and .NET implementations.

Requirements

This project requires PHP >=5.6. While most of the functionality should work down to PHP 5.4, some functionality (especially around parsing of offset for DateTimeZone) will not work with that version of PHP (see the DateTimeZone PHP docs for more info).

Installation

To install via Composer, from terminal, run:

Usage

This package provides PHP models for the OpenActive specifications.

It also provide a set of models for the schema.org specifications.

Finally it provides a set of classes to handle OpenActive's RPDE data feeds.

Models

The models are included under the \OpenActive\Models namespace.

You can instantiate a new model, passing an associative array, where the key is the attribute name, and the value is the attribute value.

For example, from your PHP application, run:

Please note that type enforcement is in place whenever creating a new model.

For example, providing a string to the target attribute in the example above will result in an \OpenActive\Exception\InvalidArgumentException being thrown.

A set of getters and setters for all the attributes is provided. Type enforcement is in place for setters too.

OpenActive

The OpenActive models are included under the \OpenActive\Models\OA namespace.

To instantiate a new one, see the models section, making sure you are using the right namespace from your model.

Schema.org

The Schema.org models are included under the \OpenActive\Models\SchemaOrg namespace.

To instantiate a new one, see the models section, making sure you are using the right namespace from your model.

RPDE

RpdeItem & RpdeBody are the main classes to use when generating a page for an RPDE feed.

Feed items

RpdeItem is used to create each individual item for a page. It includes a data attribute to which should be an instance of an OA Model along with metadata (id, modified, state and kind). It is left to each application developer to generate these models and metadata.

e.g. a session series collection

Feed page

RpdeBody is then used to wrap a collection of items and provide the licence and next entries expected from an RPDE page. To help keep pages valid and create an correct next link, use RpdeBody::createFromNextChangeNumber or RpdeBody::createFromModifiedId to create an RPDE page feed out of an array of RpdeItems (the constructor has been made private).

RpdeBody::createFromNextChangeNumber will check that all feed items do indeed come after the $changeNumber argument provided. It will contruct the next link based on the modified value of the newest feed item and the provided $feedBaseUrl argument.

e.g.

RpdeBody::createFromModifiedId will check that all feed items do indeed come after the $id and $modified arguments provided. It will contruct the next link based on the id and modified value of the newest feed item and the provided $feedBaseUrl argument.

e.g.

To override the default licence:

Serializing the feed page

Finally the feed page can then be serialized with Serialize RpdeBody::serialize($feedPage) which will also take care of serializing the each feed item's data attribute as JSON-LD.

See the OpenActive's guide to publishing data and the RPDE specification for more details about RPDE feeds.

Enums

Each enum is represented by a class which contains a constant for each available value.

e.g. Adding days of the week to a Schedule:

Serialization

This package provides support for JSON-LD serialization/deserialization of models and and for the \OpenActive\Rpde\RpdeBody object.

serialize($obj, $prettyPrint = false)

Returns the JSON-LD string representation of the given object $obj.

An additional parameter $prettyPrint is available to return a JSON-LD string in a human-readable format.

An example, using the \OpenActive\Models\OA\SessionSeries defined above:

Will output:

Please note: at the moment, only the OpenActive @context is rendered in the serialization output. Future versions of this package may allow to include more and/or different @context.

deserialize($data)

Returns an object from a given JSON-LD representation.

The $data argument can be a JSON-LD string, or an associative array, for example as a result of json_encode($string, true).

For example:

Will result in:

Installation

Please note: Composer is required for dependency management.

Running Tests

PHPUnit 5.7 is used to run tests.

To run the whole suite:

If you want to run the whole suite in verbose mode:

You can also run a section of the suite by specifying the class's relative path on which you want to perform tests:
