Understand No Duplicate Values for Fields | Zoho Creator Help

No duplicate values

Understand preventing duplicate values in form fields

  1. Applicable to the following fields: single line, email, number, percent, decimal, currency, date, date-time, and users
  1. Learn how to enable the No duplicate values field property

Enabling the  No duplicate values  property for a  field  forces your users to enter a unique input - an input that no existing record has in that field. Until your users enter a unique input, they will be unable to submit your form.

This validation is triggered only when your users enter an input in that field and submit the form. If your users do not enter an input, i.e., leave the field blank, form submission will not be failed. (Only when your users enter a value can the presence of duplicate values be searched)

For example, when you enable this property for an  email  field on your form, the below given is what happens when a user enters a duplicate email address (one that's already present in an existing record) and submits your form from a web browser:

  1. The  Invalid entries found  message appears in a pop-up window.

  2. Clicking  Okay  closes this pop-up and displays a message below that email field.

When a user enters a duplicate email address and submits your form from a phone or tablet:
  1. The  Invalid entries found  message appears in a pop-up window.
  2. Clicking  Done  closes this pop-up and displays a message below that email field.
