HameThread

Description

HameThread turns WordPress into a thread-based Q&A forum / support desk without a heavyweight setup. Each topic is a thread post and replies are ordinary WordPress comments, so everything you already know about moderation, roles and the REST API keeps working.

It shines where a generic forum does not:

• WooCommerce product support — show a “Get support” button on a product and collect purchaser questions as threads, right inside My Account.
• Private threads — let users open threads only the author, invited people and editors can read. Perfect for paid or sensitive support.
• Best answer — mark the reply that resolved the question and flag the whole thread as Resolved.
• Block-first — drop the Thread Button block on any page to let visitors start a thread. No template editing, no code.

Features

• thread post type with a topic taxonomy
• Comment-based replies with AJAX/REST posting (no full page reload)
• Best answer & resolved / unresolved status
• Private threads with capability checks
• Auto-close threads after a period of inactivity
• Upvotes on comments
• E-mail notifications to thread subscribers
• JSON-LD (QAPage) structured data for SEO
• WooCommerce My Account support page and per-product support button
• Optionally enable comment threads on any public post type
• Admin settings under Settings → Discussion (no code required for common tweaks)

Customization

Common settings are available under Settings → Discussion:

• Thread description
• Allow users to start private threads
• Post types that get HameThread-style comment threads

Everything else is filterable. See For developers below.

For developers

Replies are standard WordPress comments and threads are a standard post type, so core hooks apply. On top of that, HameThread exposes many filters/actions. The most useful ones:

Hook

Purpose

hamethread_before_thread_form / hamethread_after_thread_form
action
Add markup/fields to the thread form

hamethread_new_thread_post_params
filter
Register extra REST parameters for new threads

hamethread_new_thread_post_arg
filter
Modify the post array before a thread is inserted

hamethread_new_thread_validation
filter

hamethread_before_comment_form / hamethread_after_comment_form

Example — add a field to the thread form and store it:

// 1. Render the field.
add_action( 'hamethread_after_thread_form', function ( $args, $default ) {
    if ( $args['post'] ) {
        return; // Only on new threads.
    }
    echo ' Notify staff';
}, 10, 2 );

// 2. Register the REST parameter.
add_filter( 'hamethread_new_thread_post_params', function ( $params ) {
    $params['notify_staff'] = [ 'type' => 'integer', 'default' => 0 ];
    return $params;
} );

// 3. React after the thread is created.
add_action( 'hamethread_new_thread_inserted', function ( $post_id, $request ) {
    if ( $request->get_param( 'notify_staff' ) ) {
        // notify…
    }
}, 10, 2 );

Example — enable comment threads on the post post type:

add_filter( 'hamethread_dynamic_comment_post_types', function ( $post_types ) {
    $post_types[] = 'post';
    return $post_types;
} );
