Widget Output Cache

Widget Output Cache uses PHP output buffering to capture the rendered output of widgets and stores it in WordPress transients. This reduces the need to regenerate widget content on every page load, especially useful for widgets that fetch remote data or run heavy queries. It is intended for site owners looking for a lightweight, no-fuss caching solution.

• PHP output buffering: Captures widget output before it is sent to the browser, enabling efficient caching.
• Transient storage: Cached widget data is stored in transients with a configurable expiration time, reducing database queries.
• Per-widget exclusion: Each widget control includes a checkbox to exclude it from caching, useful for dynamic content that should update frequently.
• Adjustable cache TTL: Use the widget_output_cache_ttl filter to set a custom cache lifetime, such as 24 hours for stable widgets.
• Automatic cache invalidation: The cache for a widget is cleared automatically when the widget is saved, ensuring fresh content is served after updates.
