Featured image & gallery

The bundled Post owns three media-library-for-laravel buckets through the HasPostMedia concern:

Each bucket uses posts.media.disk when set and posts.media.responsive_widths (a list of positive integers — any other entry throws InvalidConfigurationException; [] declares no variants); null means the media-library defaults. Responsive widths become variants named responsive-{width}.

Featured image and gallery

// Featured image (single-file — a new attach replaces the previous one)
$post->addMedia($request->file('cover'))->toMediaBucket($post->featuredBucket());
$post->featuredImage();                    // ?Media
$post->featuredImageUrl();                 // string ('' or the configured fallback when empty)
$post->featuredImageUrl('responsive-640'); // the variant once generated, else the original

// Gallery (multi-file, order preserved)
$post->addMedia($request->file('photo'))->toMediaBucket($post->galleryBucket());
$post->galleryImages();                    // Collection<int, Media>
$post->galleryImageUrls();                 // list<string>
$post->galleryImageUrls('responsive-320'); // list<string> — each variant once generated, else the original

// The configured bucket names
$post->featuredBucket();   // 'featured'
$post->galleryBucket();    // 'gallery'
$post->contentBucket();    // 'content'

Variants are generated on a queue, so featuredImageUrl($variant) and galleryImageUrls($variant) return the variant’s URL once it exists and the original’s until then — or for an unknown name — instead of failing the page.

Every other media-library method — getMedia(), getFirstMediaUrl(), hasMedia(), clearMediaBucket(), addMediaFromUrl() and the rest — is available on the post through InteractsWithMedia.

Media options

'media' => [
    'disk' => env('POSTS_MEDIA_DISK'),                                  // null = media-library default
    'featured_fallback_url' => env('POSTS_MEDIA_FEATURED_FALLBACK'),
    'responsive_widths' => [480, 960, 1440],                            // positive ints; null = media-library default, [] = no variants
    'seo_og_image' => true,
    'og_variant' => '',                                                 // '' = the original, or a variant such as 'responsive-960'
    'warm_on_publish' => true,
],

Featured image as og:image

When a post has no explicit og:image, seo()->ogImage and the JSON-LD image fall back to the featured image URL — the posts.media.og_variant variant once it is generated, the original until then or when it is ''. Turn it off with posts.media.seo_og_image.

Warm variants on publish

On PostPublished, the queued WarmPostMediaVariants listener dispatches media-library’s GenerateVariantsJob for every media in the featured, gallery and content buckets, so responsive derivatives are ready when the post goes live. It does nothing when posts.media.warm_on_publish is false, the post no longer exists, or it has no media.
