Use the code below to populate a dropdown, radio button, or checkbox field with all users of a specific role. This field will store the user's ID number, but it will display the user's display name in the field options. Make sure you select 'Use separate values' in the field options before adding this code. Change 'subscriber' to any user role and change 485 to the ID of the field you want to populate.

If your form is set up to allow editing, but you want to disallow editing when a certain field value is submitted, use the code below. Change 45 to the ID of your form, 123 to the ID of the field to check, and 'Closed' to the value that will prevent editing.

You can use the example below to remove the ID column and all of it's entry information from the .csv file of a particular form upon export.
