BBPress REST API implementation for BbApp. The library can be used independently of the full BbApp framework stack, making it reusable for any WordPress site that needs BBPress REST API functionality.

Install via Composer:

composer require thebbapp/rest-api-bbpress

• PHP >= 7.2.24
• WordPress with BBPress plugin installed and activated
• thebbapp/rest-api-wordpress-base >= 0.1.0

This library extends the WordPress REST API to provide comprehensive BBPress forum, topic, and reply functionality. It adds REST endpoints, custom fields, meta queries, and anonymous posting support for BBPress.

Initialize and register the BBPress REST API in your WordPress plugin or theme:

<?php

use BbApp\RestAPI\BbPress\BbPressRESTAPI;

// Create an instance
$bbpress_rest_api = new BbPressRESTAPI();

// Register hooks and filters (call on 'rest_api_init' hook)
add_action('rest_api_init', function() use ($bbpress_rest_api) {
    $bbpress_rest_api->register();
});

// Initialize post types and meta fields (call on 'init' hook or during plugin init)
$bbpress_rest_api->init();

The library automatically enables REST API support for BBPress post types:

• Forums: /wp/v2/forums
• Topics: /wp/v2/topics
• Replies: /wp/v2/replies

All endpoints support standard WordPress REST API operations (GET, POST, PUT, DELETE) with batch support.

The library adds several computed and meta fields to BBPress resources:

For Forums:

• menu_order - Menu order

For Forums, Topics:

• _bbp_last_active_time - UNIX timestamp of last activity
• parent - Parent post ID

For Topics:

• _bbp_reply_count - Number of replies in the topic
• _bbp_forum_id - The forum ID (in meta)

For Replies:

• _bbp_reply_count - Number of replies to this reply (nested replies)
• _bbp_reply_to - Parent reply ID

For Anonymous Posts (when bbp_allow_anonymous() returns true):

• _bbp_anonymous_name - Anonymous author name

The library extends collection endpoints with BBPress-specific query parameters:

Parent Filtering:

// Get topics in forum 123
GET /wp/v2/topics?parent=123

// Get topics in multiple forums
GET /wp/v2/topics?parent[]=123&parent[]=456

Meta Queries:

// Simple meta query
GET /wp/v2/topics?meta_key=_bbp_forum_id&meta_value=123&meta_compare==

// Advanced meta query (JSON)
GET /wp/v2/replies?meta_query[0][key]=_bbp_reply_to&meta_query[0][value]=456&meta_query[0][compare]==

Ordering by BBPress Fields:

// Order forums by menu order
GET /wp/v2/forums?orderby=menu_order

// Order topics by last active time
GET /wp/v2/topics?orderby=_bbp_last_active_time

When BBPress anonymous posting is enabled (bbp_allow_anonymous() returns true), the library:

• Allows unauthenticated POST requests to /wp/v2/topics and /wp/v2/replies
• Accepts anonymous author name and email via meta fields
• Allows anonymous comments on topics and replies

The library uses BBPress's native handlers for creating and updating topics and replies, ensuring:

• Proper validation and sanitization
• BBPress hooks and filters are triggered
• Forum statistics are updated correctly
• Subscriptions and notifications work as expected

You can extend BbPressRESTAPI to add additional functionality:

<?php

use BbApp\RestAPI\BbPress\BbPressRESTAPI;

class MyCustomBbPressRESTAPI extends BbPressRESTAPI {
    public function register(): void {
        parent::register();

        // Add your custom REST fields, routes, or filters here
        register_rest_field('forum', 'my_custom_field', [
            'get_callback' => function($post) {
                return get_post_meta($post['id'], 'my_custom_meta', true);
            },
            'schema' => [
                'type' => 'string',
                'context' => ['view', 'edit']
            ]
        ]);
    }
}
