README

Indexes YouTube and Vimeo videos found in WordPress post content and ACF fields as VideoObject schema markup (JSON-LD).

How it works

1. On save_post, the package scans post_content and all ACF fields for YouTube and Vimeo URLs (including iframe embed URLs).
2. For each unique video found, it fetches metadata via the platform's oEmbed API and builds a VideoObject schema.
3. The schemas are cached in post meta, keyed by URL. On subsequent saves, already-cached videos are reused without a new HTTP request.
4. On wp_head (singular pages only), the cached schemas are output as <script type="application/ld+json"> tags.

Installation

The package is available on Packagist.

composer require wefabric/wp-video-indexer:^1.0
php artisan package:discover

Requirements

• PHP >= 7.4
• WordPress
• Themosis framework (for hook registration and service container)
• wefabric/wp-support (for WPSupport::addHooks)

Supported URL formats

YouTube

Vimeo

Adding a new platform

Each platform is a service class implementing VideoSchemaServiceInterface:

interface VideoSchemaServiceInterface
{
    public function matches(string $url): bool;
    public function extractId(string $url): ?string;
    public function fetchSchema(string $url): array;
}

1. Create a new service class implementing the interface:

class DailymotionSchemaService implements VideoSchemaServiceInterface
{
    public function matches(string $url): bool
    {
        return strpos($url, 'dailymotion.com') !== false;
    }

    public function extractId(string $url): ?string
    {
        // extract ID from URL
    }

    public function fetchSchema(string $url): array
    {
        // fetch oEmbed data and return a VideoObject schema array
    }
}

1. Register it in VideoIndexerHook::$services:

protected array $services = [
    YouTubeSchemaService::class,
    VimeoSchemaService::class,
    DailymotionSchemaService::class, // add here
];

No other changes are needed.

Testing

composer install
./vendor/bin/phpunit

Tests cover matches(), extractId(), and fetchSchema() (including fallback behaviour) for each platform service. WordPress functions are mocked using Brain Monkey.

Post meta

Schemas are re-cached each time a post is saved. Already-cached URLs are reused without a new API call. To force a full refresh, delete the _cached_video_schemas post meta and re-save the post.
