David,
You will need to install the WorldPay Payment Module which is available from the Downloads section here:
http://www.zen-cart.com/index.php?ma...roducts_id=171
If you haven't already done so you will also need to arrange with WorldPay to open an account with them - see the install.txt file included with the module files.
I have not included French language files for this module as my schoolboy French is not up to it. What you need to do is make a copy of the includes/languages/english folder included in the download file. Rename this copy 'française'. Open each of the files within this new folder and its subfolders and make any necessary translation changes. For example in includes/languages/française/wpcallback.php
Code:
define('NAVBAR_TITLE', 'WorldPay');
define('NAVBAR_TITLE_1', 'Success - Thank You');
define('NAVBAR_TITLE_2', 'Cancelled');
would become something like:
Code:
define('NAVBAR_TITLE', 'WorldPay');
define('NAVBAR_TITLE_1', 'Succès - Merci bien);
define('NAVBAR_TITLE_2', 'Décommandé');
etc.
Place this new 'française' folder in the includes/languages folder and install the module files as per the instructions in the install.txt file.
If you do translate the WorldPay module's language files into French could you please send me a copy and I will include these with future versions of the module.
Support for the WorldPay module is available here:
