Guests Cant View Threads Plugin

[ultralad91]

I have the GCVT plug in on my forum - http://www.phoenixsupras.net

I want un-registered people to be able to see the forum sections - which they can.
And the threads - which they can.

I don't want them to see the posts in the threads - which they can not.

I do have a one area of the forum that I do want them to be able to see inside the threads. How can I achieve this??

This is the code for the plug in below.

<?php
$plugins->add_hook('showthread_start', 'gcvt_thread');
$plugins->add_hook('archive_thread_start', 'gcvt_thread');

function gcvt_info()
{
	return array(
		'name'			=> 'Guests Can\'t View Threads',
		'description'	=> 'Guests cannot view threads.',
		'website'		=> 'http://mybbplug.in/',
		'author'		=> 'Jammerx2',
		'authorsite'	=> 'http://mybbplug.in/',
		'version'		=> '1.1',
		'guid'        => '8ac34edb831b6a420c48602ed5384b59'
	);
}

function gcvt_activate()
{
}

function gcvt_deactivate()
{
}
function gcvt_thread()
{
	global $db, $mybb,$lang, $thread;

                	if($mybb->user['uid'] == 0)
                	{
                    	error("<center>You must be logged into the forum in order to view the thread.<br /><br /><a href='member.php?action=register'>Register</a> or <a href='/member.php?action=login'>Log in</a></center>  ","Error");
                	}
		
		
	
	$lang->send_thread = "";
}
?>
