How do I render this in vB 4? lol

[HMBeaty]

Been at this the past hour or so, and can't seem to get it right. I've had a look at this, which helped a little, but not entirely.

This is my old code from vB 3

PHP Code:

if ($imp_vars['do'] == 'main')
{
    $navbits = construct_navbits($navbits); 
    eval('$navbar = "' . fetch_template('navbar') . '";'); 
    eval('print_output("' . fetch_template('MYCUSTOMTEMPLATE') . '");');
} 


This is what I have so far with vB 4

PHP Code:

if ($imp_vars['do'] == 'main')
{
    $navbar = render_navbar_template($navbits);
    $templater = vB_Template::create('MYCUSTOMTEMPLATE');
    $templater->register_page_templates(); 
    print_output($templater->render());
} 


which apparently isn't correct since my navbar, navbits, and some of the rest of my template got messed up or not showing. So, using the 1st code, how would I do this in vB 4? Any help is appreciated

Erm, nevermind, I got it haha. Apparently I still had to register the variables in this section too...

PHP Code:

if ($imp_vars['do'] == 'main')
{
    $navbar = render_navbar_template($navbits);
    $templater = vB_Template::create('MYCUSTOMTEMPLATE');
        $templater->register('navbits', $navbits);
        $templater->register('navbar', $navbar);
        $templater->register('pagetitle', $pagetitle);
    $templater->register_page_templates(); 
    print_output($templater->render());
}
