Validation of individual voucher codes
At present, there is no check to verify whether individual promo codes generated according to a custom pattern result in a valid code.
Although the result is displayed in a preview, if you enter a pattern containing a hyphen (‘-’), no valid code can be generated, as hyphens appear to be reserved for the PRE and SUFFIX fields.
Example: %s%s%d%d-%d%d-%d%d%d%s
This would produce the following result: UP21-%d%d-%d%d%d%s
The pattern following the hyphen is used as the code. Although this should be noticeable during creation due to the preview, validation would nevertheless be more sensible and is requested.
