Rssemble Cards for RSS Feeds

Rssemble Cards for RSS Feeds fetches multiple RSS feeds and displays them as image card grids using OGP images. It runs entirely on WordPress built-in features (SimplePie, transients, DOMDocument) — no external services required.

Key features:

• Aggregates multiple RSS feeds with URL-based deduplication (newest date wins)
• Automatic OGP image retrieval (priority: media:content → enclosure → og:image → default image)
• Parallel OGP fetching via curl_multi (respects WP proxy settings and SSL verification)
• 8 layout types: grid, list, list_vertical, text, text_line, image_only, carousel, popup_grid
• Responsive layout (3 columns on desktop, 2 on tablet, 1 on mobile — configurable)
• FSE theme color variable support (–wp–preset–color–*) with fallback
• Hover zoom + shadow effect on cards
• Transient-based caching (no WP-Cron required)
• Configurable RSS cache duration (12 hours / 1 day / 1 week / 1 month)
• OGP image URL cached for 1 month (includes negative cache for failed fetches)
• Stale cache fallback when a feed fetch fails
• Admin UI with live preview (desktop / tablet / mobile width switching)
• Compatible with object cache (Redis, Memcached) and Cloudflare
