How to override component template in joomla if user is logged in?

Question

I am working on Joomla 1.5. I have to override Joomla default template of my component (Virtuemart). It's working fine. But problem is i have to override my template if user is logged in only. I have to check look like this :

$user = JFactory::getUser();
if($user->guest==1){

// Not override my template 

}else{


// Override this template  

}

I know my condition works, but where should I write this condition. And if the condition is wrong then how can i do this?

What I would personally do is, use 2 sub templates.

So firstly, create your template override for the view that you want to use, and then create 2 new PHP files, so you directory structure will look like this:

tmpl/
   default.php
   default_guest.php
   default_loggedin.php

In your default.php, add the following:

$user = JFactory::getUser();

if ($user->guest == 1)
{
    echo $this->loadTemplate('guest');
}
else
{
    echo $this->loadTemplate('loggedin');
}

Then in your default_loggedin.php add your code for the main template override.

In your default_guest.php, simply copy and paste the code from the default view.
