Gravity Forms IBAN validation
This add-on for Gravity Forms adds the option to validate if the usersâ€™ input is a valid IBAN bank account number.
The check is done when the user submits the form and it will show an error if the input is not correct. Only if this error is resolved the form can be actually be submitted.
In case of an invalid IBAN account number, the default Gravity Forms error message will be displayed in the language that Gravity Forms is set up in.
