Prefill Hidden Fields in Form for Airtable

Prefill them even if they're not included in the form

Form Feature

With miniExtensions form, you have the choice to allow prefilling any field, including hidden ones. You can use this feature to send out forms with some prefilled IDs, for instance, without visually showing them in the form. It works by using the prefill_fieldName=parameter. Our form prefilling function works in the same way it does on Airtable Form. Go here for more details.

Use Cases

This extension can be useful in a lot of scenarios. You can use it for:

Assign unique IDs for participants
Segment participants in different groups

💡 Update

We added an auto-submit option to go along with this feature. You can now click on a link to update a record instantly. For example, send “Click here to Confirm” in an email and it instantly updates a field’s status to “checked” (without the user seeing a form, just a success message)

Demo

Here’s an example for a form with some prefilled hidden fields. After you submit this form, the Source field (which is hidden) would be auto-filled with the word “Twitter”. You can check the results in the view below.

1. URL

Demo

The full URL in the demo above is:
https://web.miniextensions.com/lRRNiT4ZomfQVhxzpjUX?prefill_Source=Twitter

2. Embed on your site

The form can be both shared as a URL or embedded in your website.

Additionally, you can avoid having the hidden fields as part of the URL. This ensures the fields remain inaccessible to users, maintaining data privacy and control over collected information.
