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

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 it does on Airtable Form. Go here for more details.


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