Clear Cache for Me vs Nginx Cache Purge Preload

W3 Total Cache and WP Super Cache are great caching plugins, but they do not know when a widget is updated. WPEngine is the best place to host your WordPress installation, but their caching system is no smarter when it comes to updating widgets and menus. I created this plugin because my website did not see any changes when saving widgets or menus using these caching systems. Clear Cache For Me will purge ALL your cache each time you do a save without having to press an additional button. It may be overkill, which may be why it’s not built in, but some people need simplicity. In addition to clearing those pesky caching engines, Clear Cache for Me can force your browser to reload your current theme’s CSS and JS files. I modify my theme’s CSS and JS files every so often and always have trouble with the browser not getting the latest version. So now after clicking on the “Clear Cache Now!” button on the dashboard the browser will be forced to reload the current theme’s CSS and JS files. If you do not click the “Clear Cache Now!” button, the browser will cache the CSS and JS files like it normally does. The popular Qode themes has a options to set your own custom CSS and JS. Sometimes you may not see your changes for a long while because your browser is trying to get the cached file. Whenever you save your Qode’s options, the CSS and JS files will be forced to reload in the browser on the public side. Works with the following caching plugins: Autoptimize Breeze Cache Cache Enabler Cloudflare GoDaddy Cache Kinsta Cache LiteSpeed Cache Elementor (CSS cache) Premium Addons for Elementor SiteGround SuperCacher Super Page Cache WP Fastest Cache WP Optimize Cache WP Rocket WP Super Cache W3 Total Cache WPEngine Cache Clears all cache for following actions (requires a caching system above to be active): When Widgets are saved. When Customizer is saved. When Menus are saved. When a fields in Advanced Custom Fields are saved. When a Contact Form 7 form is saved. When a Formidable Form form is saved. When WooThemes settings are saved. When NextGen Gallery albums and galleries are updated (beta – may not clear cache on all actions). When Qode options are saved this plugin forces browsers to reload the custom css and custom js. When a WP Forms forms or settings are saved. When WooCommerce settings are saved. (Cache should already be clearing when products are saved.) When settings from the Insert Headers and Footers plugin by WPBeginner are saved. When Settings from a settings page is saved. This includes settings from WordPress core, Yoast SEO, and most other plugins using the Settings API. When WordPress is updated. When plugins are updated, activated, and deactivated. When WordPress, plugins, and themes are automaticallly updated. See the plugin’s homepage for more details. Note: Since some caching systems run in the shutdown hook, this plugin also runs in that hook. This means if PHP does not have enough time, some code including any hooks within the ccfm_clear_cache_for_all() function are not guaranteed to run. If you need code to run, consider using the ccfm_clear_cache_for_me_setup hook. Some plugins may have “auto purge” (like Cloudflare), but it doesn’t cover all the items this plugin covers. Developer Options ccfm_supported_caching_exists Use this filter to determine if this plugin should do anything including showing the button on the dashboard. Return true if a caching system is supported. Default: True if any of the supported caching systems is active. See Example 1 below. ccfm_admin_init or ccfm_init_actions Use this action to add hooks when cache is to be cleared. Or do any other setup activity. ccfm_clear_cache_for_me_before Use this action to clear cache from an unsupported caching system before the default caching systems clear their cache. ccfm_clear_cache_for_me Use this action to clear cache from an unsupported caching system after the default caching systems clear their cache. Example If you were using an unsupported caching system you’ll need to identify the caching plugin’s class or function which clears the cache. As an example, if the unsupported caching system called the MyOtherCache::clear_all() function, you would use the following code to get this plugin to clear the cache. <?php function my_other_cache_enable( $return = false ) { if ( class_exists( 'MyOtherCache' ) ) return true; return $return; } add_filter('ccfm_supported_caching_exists', 'my_other_cache_enable'); function my_other_cache_clear() { if ( my_other_cache_enable() ) MyOtherCache::clear_all(); } add_action('ccfm_clear_cache_for_me', 'my_other_cache_clear');

Features 🧹 Purge All Nginx Cache: Completely clear all cached data stored by Nginx. 🔄 Preload All Nginx Cache: Warm the Nginx cache with the most recent data for the entire website. 🎯 HTTP Purge (ngx_cache_purge): When the Nginx cache module (ngx_cache_purge) is available, NPP uses it as the fastest purge path. Falls back gracefully to index and filesystem purge when the module is not present. 🗂️ INDEX Purge: Leverages the preload-generated URL → Filepath index to directly resolve and purge cache without filesystem traversal. If the cache exists and is valid, purge is executed immediately for near-instant performance. ⚡ RG Purge: ripgrep-powered cache file lookup that replaces slow PHP directory scanning for single-URL purges, enabling near-instant deletes on large or FUSE-mounted caches. Automatically falls back to standard scan if unavailable. 🚀 Auto Preload Nginx Cache: Automatically preloads the cache when Auto Purge is enabled for a POST/PAGE or after the Purge All action. 🧼 Auto Purge Nginx Cache: Purge cache on Post/Page content changes, comment status updates, theme/plugin updates, or when compatible Cache Plugins trigger a purge. Nginx cache is preloaded automatically if Auto Preload is enabled (for the entire site or individual page). 🔗 Purge Scope (Related Pages): Automatically purge related pages such as the Homepage, WooCommerce Shop page, and Category/Tag archives when a single URL is purged. Optionally preload those pages to keep the cache warm. 📡 Preload Feeds: Take full control of RSS/Atom feed caching. Decide site‑wide or per‑URL whether the main feed, per‑post comment feeds, and taxonomy RSS feeds are included in the preload process. ⏰ Schedule Nginx Cache Purge & Preload via WP Cron: Automate the purge and preload process using WordPress Cron jobs. 🧭 Proxy Support for Preload: Route preload requests through a proxy server for edge-case environments and containerized deployments. ⏱️ Live Preload Progress Monitoring: Watch the Nginx cache preload process in real time — complete with a dynamic progress bar, currently processed URL, 404 tracking, server load, and total completion time. 🌐 Remote Nginx Cache Purge & Preload via REST API: Remotely trigger cache purging and preloading through REST API endpoints. ⚙️ Manual Nginx Cache Purge & Preload: Allow manual purging and preloading of cache through the table view in the Advanced Tab. 📚 Nginx Cache Analyzer: Full HIT/MISS cache analyzer dashboard, from the last preload crawl with what is currently stored in the Nginx cache. Instantly spot uncached pages and Purge or Preload them directly in the Advanced Tab. 🪫 Preload All MISS: A targeted replacement for the expensive Preload All. Instead of purging and re‑caching everything (Preload All), it targets and populates only the cache entries that are not yet warmed. Perfect for sites with high cache coverage (>50%) where a full Preload All be wasteful. 🔍 On-Page Nginx Cache Purge & Preload: Manually purge and preload Nginx cache for the currently visited page directly from the frontend. 🗝️ Custom Cache Key Support: Define a regex pattern to parse URLs based on your custom _cache_key format. 📊 Monitor Plugin and Nginx Cache Status: Monitor plugin status, cache status, and Nginx status from the Status tab. 📈 Cache Coverage Ratio: Live gauge in the WordPress dashboard widget showing the cache coverage ratio, based on the last preload snapshot. Refreshable on demand without a page reload. ☁️ Cloudflare APO Sync: Automatically mirrors NPP purge actions to Cloudflare APO to keep edge cache synchronized with your Nginx cache. 🔴 Redis Object Cache Sync: Coordinates cache invalidation between NPP and Redis Object Cache during NPP-driven operations. NPP Purge All and Preload workflows handle Redis flushing at the appropriate stage to ensure both cache layers stay aligned. 🛒 WooCommerce Auto-Purge: Automatically purges Nginx cache when WooCommerce product stock quantity changes, stock status changes (in stock / out of stock / on backorder), or when an order is cancelled and stock is restored. 🖲️ WP-CLI Support: Manage Nginx cache directly from the command line. Purge and preload cache, view status reports, inspect logs, update settings, flush cache, and manage scheduled tasks without accessing the WordPress admin dashboard. 🔒 Concurrent Purge Serialization: Atomic lock mechanism prevents simultaneous purge operations from colliding, ensuring cache integrity during concurrent admin actions or background events. 🧩 Modular by Design: Easily integrate with external scripts and automation tools. 🖥️ User-Friendly Interface: Easy-to-use AJAX-powered settings, integrated into the WordPress admin bar and dashboard for quick access. 📋 Admin Notices and Logs: Receive notifications and view logs for plugin status and all cache-related actions within the WordPress admin area. 📧 Email Notifications: Receive email alerts upon completion of preload actions, with customizable templates to suit your needs.
