Rendering a Joomla! Component View From Another Component

I have to say, I consider myself a Joomla! expert, but when I decided to render the Joomla! registration view in a module along with the login view, I found myself spending a few hours working and researching before I came up with a solution. I will show you how I was able to render the Joomla! registration view using the Joomla! framework, and you can render if from anywhere. I imagine this solution works with rendering any view (with a few tweaks). Here's the code:

// Path to the users component
$com = JPATH_SITE.DS.'components'.DS.'com_users';

// Get/configure the users controller
if (!class_exists('UsersController')) require($com.DS.'controller.php');
$config['base_path'] = $com;
$cont = new UsersController($config);

// Get the view and add the correct template path
$view =& $cont->getView('registration', 'html');

// Set which view to display and add appropriate paths
JRequest::setVar('view', 'registration');

// Load the language file
$lang =& JFactory::getLanguage();
$lang->load('com_users', JPATH_SITE);

// And finally render the view!

The basic problem was that the "component" from which I was doing the rendering was com_content, so all the Joomla! path constants were set to com_content. I was receiving errors such as "XML file not found" and "Layout default not found". Since constants can't be changed, I had to add the appropriate form/field/template paths to the registration MVC.


  1. Using this method, is there a way to set the constant JPATH_COMPONENT_ADMINISTRATOR to refer to the component that was just called for rendering?

    1. If the constant has already been set (which is probably has), you can't change a constant. Are you receiving an error, or just trying to use the shorthand constant instead of spelling out the whole path to the component?

  2. I was receiving an error because I was attempting to use the JPATH_COMPONENT_ADMINISTRATOR constant in the component that I am calling. It appears that the calling component sets that constant, so attempting to use the constant in the called component returns the path to the calling (rather than the called) component path.

  3. Is there a way to be able to load this controller based on a specific menu item id? So, basically, render the view of a specific menu item id. Your code at the moment would only load the default view.

    Thank you very much for this great tip!!!
