This plugin adds a new processor for Caldera Forms, which validates a field for a syntactically correct IBAN after submitting the form.
Please note: This processor only validates the IBANs checksum, it can't check, if the IBAN really exists.
- Download the ZIP
- Install it manually at "Plugins" -> "Add new" -> "Upload plugin"
- Activate the plugin
- Create a field for the IBAN
- Add a new "IBAN validator" processor to the form
- Insert the IBAN fields slug at the processor configuration
-> Now, when a user submits the form, the IBAN should be checked.
