Eventbrite API WordPress Plugin

The Eventbrite API plugin brings the power of Eventbrite to WordPress, for both users and developers.

Overview

Users

By connecting to your Eventbrite account, events can be displayed directly on your WordPress.org website, complete with event details and ticket information. Events will blend in with the design of any theme, and events can be filtered by organizer or venue, just like post archives.

Developers

As a developer, you get simple-to-use tools for integrating Eventbrite into your themes or plugins. Use the helper functions to remove the complexity and heavy-lifting of API calls, and take advantage of assorted template tags for displaying various event information.

Requirements

Keyring

Keyring is required for the Eventbrite API plugin to work. Once it's installed with an active connection to Eventbrite, the Eventbrite API plugin will be able to display events.

If needed, admin notices will give helpful links and prompting to get Keyring and the Eventbrite API plugin up and running. These notices will appear on the Dashboard, PLugins, Tools, and Settings admin pages until issues are resolved.

Functions

Helper Functions

eventbrite_get_events( $params, $force )

  • Get user-owned events (both public and private are returned by default).
  • $params: (array, optional) Accepted parameters and values
  • $force: (boolean, optional) Force a fresh API call, ignoring any available transient. Default is false.

eventbrite_get_event( $id, $force )

  • Retrieve a single user-owned event.
  • $id: (integer, required) Eventbrite event id
  • $force: (boolean, optional) Force a fresh API call, ignoring any available transient. Default is false.

eventbrite_search( $params, $force )

  • Search all public Eventbrite events.
  • $params: (array, optional) Accepted parameters and values. Note that not passing any parameters, while technically valid, will usually result in timeout errors. Limiting the search to user-owned events can be done by passing user.id => Eventbrite_API::$instance->get_token()->get_meta( 'user_id' ).
  • $force: (boolean, optional) Force a fresh API call, ignoring any available transient. Default is false.
