Template Class, I'm confused and really need help :(

[Justin Sampson]

Hello all,

I'm sure there must be someone here that can help me with this. When I run template.php I get this error:

Warning: The length of the needle must not be 0 in template.class on line 46

template.php:

<?
include("template.class");

$page_title = "title";
$bg_color = "white";
$user_name = "Justin";

$template = new template;

$template->register_file("home", "test.template");
$template->register_variables("home", "page_title,bg_color,user_name");
$template->file_parser("home");
$template->print_file("home")
?>

template.class:

<?
class template {
    VAR $files = array();
    VAR $variables = array();
    VAR $oppinging = '{!';
    VAR $closing = '!}';

//register file
function register_file($file_id, $file_name) {

$fh = fopen($file_name, "r") or die ("Couldn't open $file_name!");
$file_contents = fread($fh, filesize($file_name));

$this->files[$file_id] = $file_contents;
fclose($fh);
}
//end register file

//register variables
function register_variables($file_id, $variable_name) {

$input_variables = explode(",", $variable_name);

while (list(,$value) = each($input_variables)) {
$this->variables[$file_id][] = $value;
}

}
//end register variables

//file parser
function file_parser($file_id) {
$varcount = count($this->variables[$file_id]);
$keys = array_keys($this->files);

if ((in_array($file_id, $keys)) && ($varcount > 0)) {
$x = 0;
while ($x < sizeof($this->variables[$file_id])) {
$string = $this->varibales[$file_id][$x];

GLOBAL $$string;

$needle = $this->opening_escape.$string.$this->closing_escape;
$this->files[$file_id] = str_replace(
$needle,
$$string,
$this->files[$file_id]);
$x++;
}
}

}
//end file parser

function print_file($file_id) {
print $this->files[$file_id];
}
}
?>

I know it's kind of complicated but I really need to get this working!

Thanks for the help,
Justin Sampson

There wer ea few typos and messed up variable names in there.

<?
class template {
    VAR $files = array();
    VAR $variables = array();
    VAR $oppinging = '{!';
    VAR $closing = '!}';

//register file
function register_file($file_id, $file_name) {
    $fh = fopen($file_name, "r") or die ("Couldn't open $file_name!");
    $file_contents = fread($fh, filesize($file_name));
    
    $this->files[$file_id] = $file_contents;
    fclose($fh);
    }
//end register file

//register variables
function register_variables($file_id, $variable_name) {
    $input_variables = explode(",", $variable_name);
    while (list(,$value) = each($input_variables)) {
        $this->variables[$file_id][] = $value;
        }
    }
//end register variables

//file parser
function file_parser($file_id) {
    $varcount = count($this->variables[$file_id]);
    $keys = array_keys($this->files);
    
    if ((in_array($file_id, $keys)) && ($varcount > 0)) {
        $x = 0;
        while ($x < sizeof($this->variables[$file_id])) {
            $string = $this->variables[$file_id][$x];
            
            GLOBAL $$string;
            $needle = $this->oppinging.$string.$this->closing;
            $this->files[$file_id] = str_replace($needle,$$string,$this->files[$file_id]);
            $x++;
            }
        }
    
    }
//end file parser

function print_file($file_id) {
    print $this->files[$file_id];
    }
}

Thanks yet again Freddy, I guess I needed some sleep.
