I'm having some small issues on trying to redirect a function to another function that's inside the same "Class"

Here is the code for Admin.php

Code:
<?php

class Admin extends MainController{
	function __construct(){
			parent::__construct();
			$this->view->url	=	$this->config->url;
			$this->view->ID 	  = get_class($this);
			$this->view->Title = "iOwn Admin";
			$this->view->loginMessage = "";			
			if($_SESSION['user'] == ""){
				header("location:../Logout");
				exit(0);
			}else{
				
				$sql = "SELECT * FROM users WHERE username = :username ";
				$arr = array(":username" => $_SESSION['user']);
				$ctr = $this->database->DBCtr($sql,$arr);
				
				if($ctr > 0){
					$usr = $this->database->DBQry($sql,$arr);
					$this->view->usr = $usr[0]['username'];
					$role = $usr[0]['admin'];
				if($role == 1){
				header("location:../Admin");
				exit(0);
				}
			}	
		}
	}

	function AddAdmin(){
		$this->view->url	=	$this->config->url;
		$this->view->ID 	  = get_class($this);
		$this->view->Title = "iOwn > Admin > Add Admin";
		$this->view->render('Admin/AddAdmin');
	}	

}
?>
Code:
if($role == 1){
				header("location:../Admin");
Is it possible to make this redirect to
Code:
function AddAdmin
