powershell how to use Add-PnPField -type user to set to users only

Question

I'm reasonably new to PowerShell and have created a script to deploy a list into SharePoint using PNP. One of the list items is a user field that is created with the following line

Add-PnPField -List "Owners" -DisplayName "Owner" -InternalName Owner -Type User -Required -ErrorAction Continue -AddToDefaultView | Out-Null

Can anyone tell me how I set this field to be users only and not users & groups?

Answer 1

Use Add-PnPFieldFromXml instead.

Try something like:

$xml = '<Field Type="User" DisplayName="Owner" List="Owners" Required="FALSE" ID="{<guid>}" -Required UserSelectionMode="PeopleOnly" StaticName="Owners" Name="Owners" Description=""/>'
Add-PnPFieldFromXml -FieldXml $xml

Answer 2

You could try below PowerShell.

$field = Get-PnPField -List "Owners" -Identity "Owner"
$field = Add-PnPField -List "Owners" -DisplayName "Owner" -InternalName Owner -Type User -Required -ErrorAction Continue -AddToDefaultView | Out-Null
Set-PnPField -List "Owners" -Identity $field.Id -Values @{"SelectionMode"=0}
