PowerShell script to get the ShowInEditForm property for a site column. i do not want to use PnP PowerShell - powershell

Question

I am trying this script to get the ShowInEditForm property of a site column and then set it to False:-
Connect-SPOService -Url https://****-admin.sharepoint.com/
Get-SPOSite -Identity https://***.sharepoint.com/
$column = Get-SPOField -Identity "CarNumber"
but i am getting this error:-
Get-SPOField : The term 'Get-SPOField' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
any advice please?

Answer 1

The Get-SPOField is not a valid cmdlet, you should use the Get-PnPField cmdlet to get the fields.

Answer 2

Try using this PowerShell:
#Set Variables
$SiteURL= "https://crescent.sharepoint.com/sites/Marketing"
$InternalName = "MyEditor"
#Setup Credentials to connect
$Cred = Get-Credential
Try {
#Setup the context
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.UserName,$Cred.Password)
#Get the Web
$Web = $Ctx.Web
$Ctx.Load($Web)
#Get the Site Column
$SiteColumn = $Web.Fields.GetByInternalNameOrTitle($InternalName)
$Ctx.Load($SiteColumn)
$Ctx.ExecuteQuery()
#Get the Site Column's Name,Type, ID and Group
$SiteColumn | Select Title, TypeDisplayName, ID, Group
}
Catch {
write-host -f Red "Error: " $_.Exception.Message
}
