Frequently asked questions

What is form field validation?

Form field validation is the process of checking user-submitted data according to a set of predefined rules to ensure it meets specific criteria (e.g., correct email format, minimum password length, required fields).

Why is my form field validation not working?

Common reasons include incorrect validation rules, JavaScript errors, conflicting scripts, improper server-side validation setup, or issues with your form builder's configuration.
