🔍 Submission Duplicate Check

What is Duplicate Submission Check?​

The "Submission Duplicate Check" feature in FormNX enables you to implement validation to prevent duplicate or multiple times form submissions by same person.

Duplicate submissions can lead to inaccurate data and complicate data analysis. With this feature, you can ensure that each form submission is unique and distinct.

Steps to Configure Duplicate Check​

To avoid duplicate submissions for forms in FormNX, follow these steps:

Steps to Configure Duplicate Check

  1. Access Settings Tab: To enable Duplicate check, click on "Settings" tab & then click on "General" section.

  2. Enable it: Check the Enable checkbox to enable the Duplicate check for your form.

  3. Choose Mechanism: Select the mechanism you want to use for duplicate checks:

    • Duplicate check based on users IP Address:​

      This mechanism prevents duplicate submissions from the same IP address.

    • Duplicate check based on Input Field (like email):​

      Choose an input field from your form based on which the duplicate validation will occur (e.g., email).

  4. Error Message: Provide a clear and informative error message that will be displayed to users if a duplicate submission is detected. This message should instruct users on how to proceed or why their submission was rejected.

Save Your Settings: Be sure to save your form.

Example Use Cases​

Here are a few examples illustrating how the "Duplicate Submission Check" feature in FormNX can be helpful:

Newsletter Signup​

Suppose you have a newsletter signup form on your website.

To prevent users from signing up multiple times with the same email address, you can enable duplicate checks based on the email input field.

If a user attempts to submit the same email address twice, they will receive an error message informing them the same email has already subscribed to your newsletter.
