Code snippet to get bbPress talking with Support Hub correctly

functions.php

// this code does two things:

// 1) sets the 'support_hub' return parameter to the xmlrpc getUser request. In here we can include additional options to display within Support Hub when replying to a bbPress post. Currently we have 'Mark Thread as Resolved' as an option. This option gets passed back to bbPress via XMLRPC when replying to a post from Support Hub, so we can action this. 

// 2) a hook for xmlrpc insert post to detect if we're posting a forum thread. This runs the standard bbPress update hooks to ensure all the bbPress meta values are updated correctly after posting a reply. We also look for any custom options (e.g. mark as resolved) and perform actions based on those as well.

// UPDATE: instead of adding this code, try using this bbPress Support plugin: https://github.com/dtbaker/bbPress-Support-Forums it does everything (making threads as resolved, feature voting,  etc..)

// this is for SupportHub to operate correctly, passing the envato_codes as a meta key along with user requests.
//apply_filters( 'xmlrpc_prepare_user', $_user, $user, $fields )
add_filter('xmlrpc_prepare_user', '_bbps_xmlrpc_prepare_user', 10, 3);
function _bbps_xmlrpc_prepare_user($_user, $user, $fields){
	$envato_codes = get_user_meta( $_user['user_id'], 'envato_codes', true );
	if ( is_array( $envato_codes ) ) {
		$_user['envato_codes'] = $envato_codes;
	}
	$_user['support_hub'] = array(
		'reply_options' => array(
            array(
