Pronamic Gravity Forms IBAN Validation

This plugin adds IBAN validation to Gravity Forms.

The check digits which are part of the IBAN are used in a mathematical calculation to validate the IBAN. Also, the format is validated against the rules of the country that is specified in the given IBAN.

To validate a text field as IBAN, simply add the CSS class gf-iban-validation to the field in the Gravity Forms form editor.
