Hi, I’ve recently run into an issue where I’m pulling Advanced Custom Fields options page data onto a page, when I update this data it doesn’t trigger the cache to be cleared. This means I have to remember to manually clear the cache any time I update Advanced Custom Fields options page data.

I’ve done some googling and checked through the settings, and have seemed to come up short on finding any settings in W3 cache to address this issue.

As a workaround I’ve created the below snippet to clear the cache for me anytime I update ACF date. Any help or insight would be appreciated.

function flush_w3tc_cache_on_acf_update( $post_id ) {
// Check if W3 Total Cache is active.
if ( function_exists( 'w3tc_flush_all' ) ) {
// Clear all caches.
w3tc_flush_all();
// Only set the transient if not an AJAX request.
if ( ! ( defined( 'DOING_AJAX' ) && DOING_AJAX ) ) {
set_transient( 'w3tc_cache_notice', 'success', 30 );
}
} else {
// Only set the transient if not an AJAX request.
if ( ! ( defined( 'DOING_AJAX' ) && DOING_AJAX ) ) {
set_transient( 'w3tc_cache_notice', 'error', 30 );
}
}
}
add_action( 'acf/save_post', 'flush_w3tc_cache_on_acf_update', 20 );

/**
* w3tc_cache_admin_notice
*
* Displays an admin notice indicating whether the W3 Total Cache flush was successful.
* This notice only appears in the WordPress admin area.
*/
function w3tc_cache_admin_notice() {
if ( $notice = get_transient( 'w3tc_cache_notice' ) ) {
if ( $notice === 'success' ) {
echo '<div class="notice notice-success is-dismissible"><p>W3 Total Cache was successfully cleared.</p></div>';
} elseif ( $notice === 'error' ) {
echo '<div class="notice notice-error is-dismissible"><p>W3 Total Cache clearing failed. Please check your settings.</p></div>';
}
// Clear the transient so the notice doesn't persist.
delete_transient( 'w3tc_cache_notice' );
}
}
add_action( 'admin_notices', 'w3tc_cache_admin_notice' );
