Get someone else's User ID for Message - joomla

Question

I'm unable to get someone's user ID from their Kunena profile to open a new private message with the recipient name already inserted. The closest I got was the following code, which inserts my own username...
defined('_JEXEC') or die ();
class KunenaPrivateUddeIM extends KunenaPrivate
{
protected $uddeim = null;
protected $params = null;
/**
* #param $params
*/
public function __construct($params)
{
$this->params = $params;
if (!class_exists('uddeIMAPI'))
{
return;
}
$this->uddeim = new uddeIMAPI();
if ($this->uddeim->version() < 1)
{
return;
}
}
/**
* #param $userid
*
* #return string
*/
protected function getURL($userid)
{
static $itemid = false;
if ($itemid === false)
{
$itemid = 0;
if (method_exists($this->uddeim, 'getItemid'))
{
$itemid = $this->uddeim->getItemid();
}
if ($itemid)
{
$itemid = '&Itemid=' . (int) $itemid;
}
else
{
$itemid = '';
}
}
return JRoute::_('index.php?option=com_uddeim&task=new&recip=' . (int) $userid . $itemid);
}
/**
* #param $userid
*
* #return mixed
*/
public function getUnreadCount($userid)
{
return $this->uddeim->getInboxUnreadMessages($userid);
}
/**
* #param $text
*
* #return string
*/
public function getInboxLink($text)
{
if (!$text)
{
$text = JText::_('COM_KUNENA_PMS_INBOX');
}
return '' . $text . '';
}
/**
* #return string
*/
public function getInboxURL()
{
$user = JFactory::getUser($userid);
return JRoute::_('index.php?option=com_uddeim&task=new&recip=' . ($user ->id));
}
}

Answer 1

Change this line:
return JRoute::_('index.php?option=com_uddeim&task=new&recip=' . (JFactory::getUser()->id));
to the following 2 lines:
$user = JFactory::getUser($userid);
return JRoute::_('index.php?option=com_uddeim&task=new&recip=' . ($user ->id));
You can check this post that we have written some time ago (it was written for Joomla 2.5, but it still works, except that you have to remove the &) on how to retrieve non-cached users in Joomla: http://www.itoctopus.com/how-to-retrieve-the-non-cached-user-information-from-joomla
