Field Validations
Field validation that stops bad data at the form
Form field validation checks what a visitor typed before the submission goes through, so typos, empty required fields, and malformed emails never reach your inbox. Neural Forms validates fields in the free plugin, and pairs it with spam protection so what does arrive is worth reading.
Validation rules
The checks you can set per field
Neural Forms supports validation rules including required fields, email format checks, and minimum and maximum length. Set the rule when you configure the field in the builder; visitors get corrected at the form instead of submitting broken data.
Multi-step and repeater
Validation in multi-step and repeater forms
Validation is not limited to flat forms. In multi-step forms, each step is validated before the visitor moves on, so errors surface where they happen rather than at the final submit. On paid plans (Starter $99/yr and Agency $199/yr), the Repeater field applies validation per row, so every repeated entry, each job in a work history, each item on an order, is checked on its own.
Spam protection
Validation plus spam protection
Validation catches honest mistakes; it does not stop bots. Neural Forms layers Cloudflare Turnstile, reCAPTCHA v2, and AI spam detection on top, so the submissions that reach your lead inbox pass both a format check and a spam check.
