While we don’t recommend this at all, you can do this as follows:
- Open this file in your Zen Cart installation:
/includes/modules/payment/payfast.php
- Find the text:
$currency = 'ZAR';
- Change ZAR to the currency code for your non-standard currency (eg. ZA)
- Save the file
This will set the module to use your non-standard currency code.
Please note: If you upgrade to a new version of the PayFast module at a later stage, your changes will be overridden. So remember to save your changes before doing so.
