Purge and force purge does not work, must purge at CF

Hi @dariobros,

Thank you for reaching out to us and sharing your concerns.

We are not aware of any widespread issues with the “Force Purge” or “Purge All” functionality in the plugin. Based on our tests and feedback from other users, these features are working as expected. However, we understand that each setup can be unique, and we’re here to help investigate further.

To assist you better, could you please provide the following details?

1- The version of the plugin and WordPress you are currently using.
2- Any error messages or logs that appear when attempting to use the “Force Purge” or “Purge All” feature.
3- Confirmation of any server-side caching or custom Cloudflare settings that might interfere with purging (e.g., custom Workers or rules).
Any specific steps or patterns you’ve noticed where the purge function does not behave as expected.

These details will help us pinpoint the cause of the issue and provide tailored guidance.

We appreciate your patience and look forward to your reply to assist further!

Best regards,

thanks very much for your reply.

i have followed your instructions about the setup and have not changed any settings on the cloudflare side, so only one page rule written automatically by your plugin.
no error logs and no access log either. I tried a few approaches and somehow the cached pages did not update (eg. incogonito mode chrome kept loading cached page).
but this solution seems to work > I flush the cache at Cloudflare level and add purge flash hook on post save.

so now when i have a page open in chrome and reload it, the cf-cache-status: is MISS and on another page load it`s HIT, and AGE gets reset.

function purge_cloudflare_cache_on_post_save( $post_id ) {

    // Avoid triggering during autosave or if not a valid post type

    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {

        return;

    }

    // Cloudflare Zone ID and API Token

    $zone_id = 'xxxxxxx';

    $api_token = 'xxxxxxx'; 

    // Build the API endpoint

    $url = "https://api.cloudflare.com/client/v4/zones/{$zone_id}/purge_cache";

    // Body for the API request (purge all cache)

    $body = json_encode( array( 'purge_everything' => true ) );

    // Set up request headers

    $headers = array(

        'Content-Type' => 'application/json',

        'Authorization' => "Bearer {$api_token}",

    );

    // Send the request to Cloudflare API

    $response = wp_remote_post( $url, array(

        'method'  => 'POST',

        'body'    => $body,

        'headers' => $headers,

    ) );

    // Optional: Log the response for debugging

    if ( is_wp_error( $response ) ) {

        error_log( 'Cloudflare Cache Purge Failed: ' . $response->get_error_message() );

    } else {

        $response_body = wp_remote_retrieve_body( $response );

        error_log( 'Cloudflare Cache Purge Response: ' . $response_body );

    }

}

add_action( 'save_post', 'purge_cloudflare_cache_on_post_save' );

function purge_cache_on_save_or_update( $post_id, $post, $update ) {

    // Prevent autosave from triggering cache purge

    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {

        return;

    }

    // Purge the cache

    do_action( "swcfpc_purge_cache" );

    // Log cache purge success in the access log

    if ( did_action( "swcfpc_purge_cache" ) ) {

        error_log( "Cache purged for post ID: " . $post_id . " on " . date( 'Y-m-d H:i:s' ) );

    } else {

        error_log( "Cache purge failed for post ID: " . $post_id . " on " . date( 'Y-m-d H:i:s' ) );

    }

    // Add a transient to show an admin notice

    set_transient( 'cache_purge_notice', true, 10 );

}

add_action( 'save_post', 'purge_cache_on_save_or_update', 10, 3 );

function display_cache_purge_notice() {

    if ( get_transient( 'cache_purge_notice' ) ) {

        echo '<div class="notice notice-success is-dismissible"><p>Cache purged successfully!</p></div>';

        delete_transient( 'cache_purge_notice' );

    }

}

add_action( 'admin_notices', 'display_cache_purge_notice' );
