Title: Implement warm on edit Last modified: October 2, 2024 --- # Implement warm on edit * [p15h](https://wordpress.org/support/users/prestonwordsworth/) * (@prestonwordsworth) * [1 year, 6 months ago](https://wordpress.org/support/topic/implement-warm-on-edit/) * Currently, although the legend say `On their publication and edit`, the implementation doesn’t trigger the warmer upon edit. * ```wp-block-code public function populate_enqueue( $new_status, $old_status, $post ) { if ( 'publish' === $new_status ) { $posts_enqueue = Cache_Warmer::$options->get( 'cache-warmer-posts-enqueue' ); if ( ! in_array( $post->ID, $posts_enqueue, true ) ) { $posts_enqueue[] = $post->ID; Cache_Warmer::$options->set( 'cache-warmer-posts-enqueue', $posts_enqueue ); } } } ``` * Here’s an example of a trigger that does respond to an edit, from the CF page cache plugin: * ```wp-block-code $purge_actions = array( 'deleted_post', // Delete a post 'wp_trash_post', // Before a post is sent to the Trash 'clean_post_cache', // After a post’s cache is cleaned 'edit_post', // Edit a post - includes leaving comments 'delete_attachment', // Delete an attachment - includes re-uploading 'elementor/editor/after_save', // Elementor edit 'elementor/core/files/clear_cache', // Elementor clear cache );foreach ($purge_actions as $action) { add_action($action, array($this, 'purge_cache_on_post_edit'), PHP_INT_MAX, 2); }function purge_cache_on_post_edit($postId) { static $done = []; if (isset($done[$postId])) { return; } // Do not run this on the WordPress Nav Menu Pages global $pagenow; if ($pagenow === 'nav-menus.php') return; if (($this->main_instance->get_single_config('cf_auto_purge', 0) > 0 || $this->main_instance->get_single_config('cf_auto_purge_all', 0) > 0) && $this->is_cache_enabled()) { $current_action = function_exists('current_action') ? current_action() : ""; $this->modules = $this->main_instance->get_modules(); $error = ''; $validPostStatus = ['publish', 'trash', 'private']; $thisPostStatus = get_post_status($postId); if (get_permalink($postId) != true || !in_array($thisPostStatus, $validPostStatus)) { return; } if (is_int(wp_is_post_autosave($postId)) || is_int(wp_is_post_revision($postId))) { return; } if ($this->main_instance->get_single_config('cf_auto_purge_all', 0) > 0) { $this->purge_all(); return; } $savedPost = get_post($postId); if (is_a($savedPost, 'WP_Post') == false) { return; } $urls = $this->get_post_related_links($postId); $this->purge_urls($urls); $this->modules['logs']->add_log('cache_controller::purge_cache_on_post_edit', "Purge Cloudflare cache for only post id {$postId} and related contents - Fired action: {$current_action}"); $done[$postId] = true; } } ``` Viewing 1 replies (of 1 total) * Thread Starter [p15h](https://wordpress.org/support/users/prestonwordsworth/) * (@prestonwordsworth) * [1 year, 6 months ago](https://wordpress.org/support/topic/implement-warm-on-edit/#post-18050640) * I’ve now identified the reason why `populate_enqueue` doesn’t get triggered on post update: it’s because it’s using the `transition_post_status` hook, which only fires when you refresh the page, whereas post update is usually done via Ajax. * So, there’s two ways to go about this. One could use the `edit_post` hook like in the purge action above. Or one could register a custom hook: * ```wp-block-code add_action('wp_ajax_' . WPACU_PLUGIN_ID . '_preload', array($this, 'ajaxPreloadGuest'), PHP_INT_MAX); /** * This is triggered when /admin/admin-ajax.php is called (default WordPress AJAX handler) */ public function ajaxPreloadGuest() { // Check nonce if ( ! isset( $_POST['wpacu_nonce'] ) || ! wp_verify_nonce( $_POST['wpacu_nonce'], 'wpacu_ajax_preload_url_nonce' ) ) { echo 'Error: The security nonce is not valid.'; exit(); } $pageUrl = isset($_POST['page_url']) ? $_POST['page_url'] : false; $pageUrlDomain = parse_url($pageUrl, PHP_URL_HOST); $pageUrlPreload = add_query_arg( array( 'wpacu_preload' => 1 ), $pageUrl ); // Check if the URL is valid if (! filter_var($pageUrlPreload, FILTER_VALIDATE_URL)) { echo 'The URL '.$pageUrlPreload.' is not valid.'; exit(); } // Check the domain from "page_url" parameter if (strpos(site_url(), $pageUrlDomain) === false) { echo 'Error: Possible hacking attempt! The host name of the requested URL is not the same as the one of "Site Address (URL)" from "Settings" - "General".'; exit(); } // Check privileges if (! Menu::userCanAccessAssetCleanUp()) { echo 'Error: Not enough privileges to perform this action.'; exit(); } $response = wp_remote_get($pageUrlPreload); if (is_wp_error($response)) { // Any error generated during the fetch? Print it echo 'Error: '.$response->get_error_code(); } else { // No errors echo 'Status Code: '.wp_remote_retrieve_response_code($response).' / Page URL (preload): ' . $pageUrlPreload . "\n\n"; echo isset($response['body']) ? $response['body'] : 'No "body" key found from wp_remote_get(), the preload might not have triggered'; } exit(); } /** * This is triggered when /admin/admin-ajax.php is called (default WordPress AJAX handler) */ public function ajaxPreloadGuest() { // Check nonce if ( ! isset( $_POST['wpacu_nonce'] ) || ! wp_verify_nonce( $_POST['wpacu_nonce'], 'wpacu_ajax_preload_url_nonce' ) ) { echo 'Error: The security nonce is not valid.'; exit(); } $pageUrl = isset($_POST['page_url']) ? $_POST['page_url'] : false; $pageUrlDomain = parse_url($pageUrl, PHP_URL_HOST); $pageUrlPreload = add_query_arg( array( 'wpacu_preload' => 1 ), $pageUrl ); // Check if the URL is valid if (! filter_var($pageUrlPreload, FILTER_VALIDATE_URL)) { echo 'The URL '.$pageUrlPreload.' is not valid.'; exit(); } // Check the domain from "page_url" parameter if (strpos(site_url(), $pageUrlDomain) === false) { echo 'Error: Possible hacking attempt!
