HameThread

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 Type 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 Add validation errors ( WP_Error )

hamethread_new_thread_inserted action React after a thread is created

hamethread_before_comment_form / hamethread_after_comment_form action Add markup/fields to the comment form

hamethread_new_comment_params filter Modify comment data before insert

hamethread_default_subscribers / hamethread_subscribers filter Control who is notified

hamethread_user_can_start_private_thread filter Allow private threads

hamethread_user_can_comment / hamethread_user_can_post filter Capability checks

hamethread_dynamic_comment_post_types filter Post types that get comment threads

hamethread_post_setting / hamethread_post_type / hamethread_taxonomy filter Customize the post type & taxonomy

hamethread_template filter Override template parts

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 '<label><input type="checkbox" name="notify_staff" value="1" /> Notify staff</label>'; }, 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; } );
