Yes... you are right when you say an existing (older) template may not be compatible with zc 1.3.9c ...
Upgrading templates is not usually that difficult because most consist only of TPL and LANGUAGE files (with a few having some module files too).
However... to your question.
This is what I would do...
On your LOCAL MACHINE...
Open up a fresh copy of zencart 1.3.9c
navigate to:
includes/templates/classic/template_info.php , and open it for editing in a plain text editor:
You will see:
PHP Code:
<?php
/**
* Template Information File
*
* @package templateSystem
* @copyright Copyright 2003-2006 Zen Cart Development Team
* @copyright Portions Copyright 2003 osCommerce
* @license http://www.zen-cart.com/license/2_0.txt GNU Public License V2.0
* @version $Id: template_info.php 4226 2006-08-24 02:23:25Z drbyte $
*/
$template_name = 'Classic Contemporary Green';
$template_version = 'Version 1.3.5';
$template_author = 'Zen Cart Team (c) 2006';
$template_description = 'This template set is designed to be easily modified using only the style sheet to change colors, fonts, and the store logo. Three images are required; logo.jpg, header_bg.jpg, and tile_back.gif.';
$template_screenshot = 'scr_template_default.jpg';
?>
Change it thus:
PHP Code:
<?php
/**
* Template Information File
*
* @package templateSystem
* @copyright Copyright 2003-2006 Zen Cart Development Team
* @copyright Portions Copyright 2003 osCommerce
* @license http://www.zen-cart.com/license/2_0.txt GNU Public License V2.0
* @version $Id: template_info.php 4226 2006-08-24 02:23:25Z drbyte $
*/
$template_name = 'My Template';
$template_version = 'Version 1.3.9';
$template_author = 'My name - 2010';
$template_description = 'This is my new template';
$template_screenshot = '';
?>
SAVE it
Then, go through ALL the folders, SUB-folders and even the SUB-SUB-folders in:
templates
languages
modules
... and wherever you see a folder called "classic"...
... change that folder's name to my_template
You now have your exact clone of classic (called my_template) which you can FTP to your server.
So you just ftp all those my_template folders and the new template_info.php file to their respective forlders and sub/folders
