Forminator Fields Dynamic Prepopulation

Hi @vestart,

I hope you are keeping well and thank you for reaching out to us.

Could you please share an export of the form along with the custom code used to populate the select field via Google Drive or Dropbox?

I hope the following guide comes in handy: https://wpmudev.com/docs/wpmu-dev-plugins/forminator/#import-export

We can take a look and try to assist in getting the form to work. However, please note that custom code falls outside our support scope, and you may need to hire a developer for this. WordPress provides a jobs directory here: https://jobs.wordpress.net/

Best Regards,
Nebu John

Hi @vestart,

The form validation error you’re encountering is likely due to the form options not being synchronized between the frontend and backend.

Trying to fill the select field with JS will show the same error because the field doesn’t have the same option available on the backend.

To resolve this, you’ll need to fill in the form’s options on the backend as well. The Forminator API provides a method to update form field options programmatically, which can help you achieve this.

A general approach you can follow is to utilize the update_form_field() method to update field options in the backend. This ensures that the field options are correctly recognized by the form’s validation system, then Identify the form and field IDs and generates dynamic options to update the form field.

You can refer to this doc for more info:
