Hello,
I have created a form, but one input field is a field to add an EAN18 barcode field. This barcode has 18 digits, but I also have a script to validate if the barcode is valid. Is there a way to add this script to this specific field?
Best regards,
Joeri.
What sort of script are you talking about for validating that barcode: JavaScript or PHP script? If it's JavaScript you will need to add it on the front end when the form is displayed.
If it's PHP, you can use the gform_validation filter to ensure the barcode is in the proper format, and if not, return a validation error: http://www.gravityhelp.com/documentation/page/Gform_validation
