checking if a page requires authentication

[graymic]

Now I'm trying a slightly different approach I have the current code:

    // Ensures the user is required to be logged in on the pageauthenticator.
    public function checkAuthPage($controller_name = null, $action_name = null, $condition = false) {
		
		global $_pageauthenticator;
		
		// check to see if the controller name exists within the authenticator.
		if ( array_key_exists($controller_name, $_pageauthenticator) )
		{
						
			// Check to see if we're also on the action page - otherwise we're just on the controller.
			if (array_key_exists('exceptions', $_pageauthenticator[$controller_name]))
			{			
			
				// Does the action page require a login?
				$exceptions = explode(',', $_pageauthenticator[$controller_name]['exceptions']);
				
				foreach($exceptions as $k => $v)
				{
					$aname = trim($v);
					if ($action_name == $aname)
					{
						return false;
					}					
				}
				
			}
			else
			{
				// Requires login?
				if($_pageauthenticator[$controller_name]['requires_login'])
				{	
					if (!$condition) $this->redirectUser();
					else return false;
				}
				else
				{
					return false;
				}		
			}
			
			if (!$condition) $this->redirectUser();
			else return false;
			
		}
		    	
    }

Which checks against an array like so:

$_pageauthenticator = array (
	
	'main' 				=> array ('requires_login' => true, 'exceptions' => 'login, register'),
	'accountSettings'	=> array ('requires_login' => true, 'exceptions' => ''),
	'courseManager'		=> array ('requires_login' => true, 'exceptions' => ''),
	'companyManager'	=> array ('requires_login' => true, 'exceptions' => '')
	
);

Now there is nothing crazy about this it's just probably really bad code + the fact I am half asleep at this hour. So, out of curiosity why would only 'main' be working correctly, but not the other pages?
