Add Field or Column to ContentType and set the column order

When you run below script it will add a field to content type and set the order. For my field I want to set the order next to ‘SAC Doc’ filed. For that I am reading existing index of ‘SAC Doc’ field and setting to my new field.

For column order you can refer this post as well

It will create a log file in your location where you are running your script

function SetColumnOrder([Microsoft.SharePoint.SPContentType]$contentType)
            #Write-Host $
            [Microsoft.SharePoint.SPFieldLinkCollection]$flinks = $contentType.FieldLinks;
               #array object
               $fieldsArray = New-Object 'System.Collections.Generic.List[string]';

          #Read all the InternalNames of the FieldLinks into a list
          foreach($fieldLink in $flinks){
              $fieldchkboxInternalName =$contentType.Fields["SAC DOC"].InternalName
             # Write-Host $fieldchkboxInternalName
              $fieldDDLInternalName =$contentType.Fields["ddlTest"].InternalName

              $indexChkbox = $fieldsArray.IndexOf($fieldchkboxInternalName)
                    #Write-Host "checkbox index:" $indexChkbox
                    $indexDDL = $fieldsArray.IndexOf($fieldDDLInternalName)
                     #Write-Host "ddlindex:"  $indexDDL
                     #Write-Host  "fieldsArraycount" $fieldsArray.Count
                    if($indexChkbox -ne $indexDDL )
                          if($indexChkbox -le $fieldsArray.Count -1){
                                     Write-Host "SAC ddl index:"  $fieldsArray.IndexOf($fieldDDLInternalName)
                                     $msg = ("{0},{1}" -f "SAC ddl index order :", $fieldsArray.IndexOf($fieldDDLInternalName))
                                    $msg | out-file -FilePath $logfile  -append
                        #  $fieldsArray.Add($fieldDDLInternalName);
             #Add the array to the reorder
             #Update the ContentYpe
