file_parser error

[stefanoostwegel]

Hi, i created my own template, but i an error in it. The error is:

Fatal error: Call to undefined function: file_parser() in c:\phpdev\www\public\daalhof\templates\template.tpl on line 16

This is the code of the template:

//Register a few variables
$template->register_variables("home", "page_title,bg_color");
$template->file_parser("home"); //line 16
//output the file to the browser
$template->print_file("home");

?>

If it's not clear here is:

#------------------#
| template.class |

VAR $files = array();

and here is

#---------------#
| template.tpl |
#---------------#

<?
include("template.class");

//assign a few variables
$page_title = "Welkom op winkelcentrum-daalhof.nl";
$bg_color = "white";

//Instantiate a new object
$template = new template;

//register the file index, assigning the pseudonym "home"
$template->register_file("home", "index.php");

//Register a few variables
$template->register_variables("home", "page_title,bg_color");
$template->file_parser("home");
//output the file to the browser
$template->print_file("home");

?>

Can somebody help me out??
