SharePoint Online：使用 PowerShell 更新托管元数据字段值

要求：在 SharePoint Online 中使用 PowerShell 更新托管元数据列值。

SharePoint Online：用于更新托管元数据字段值的 PowerShell CSOM 脚本

在 SharePoint Online 中，您可以使用 PowerShell 设置托管元数据列。本博文将向您展示如何使用 PowerShell 更新托管元数据列。我们将分享一些使用 CSOM 和 PnP PowerShell 更新托管元数据列值的脚本示例。

[玩转系统] SharePoint Online：使用 PowerShell 更新托管元数据字段值

假设数据已填充到术语库中，类似于您在上面看到的内容，以下是用于设置托管元数据列的值的 PowerShell 脚本：


#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
Add-Type -Path "C:\Program Files\Common Files\microsoft shared\Web Server Extensions\ISAPI\Microsoft.SharePoint.Client.Taxonomy.dll"
 
#Set parameter values
$SiteURL="https://crescent.sharepoint.com/sites/Ops/"
$ListName="Projects"
$ItemID="1"
$TaxonomyFieldTitle="Region"

#Termset parameters
$TermGroupName="Regions"
$TermSetName="MENA"
$TermName="UAE"

Try { 
        #Get Credentials to connect
        $Cred= Get-Credential
        $Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)
 
        #Setup the context
        $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
        $Ctx.Credentials = $Credentials

        #Get the list and Item
        $List=$Ctx.web.Lists.GetByTitle($ListName)
        $Item = $List.GetItemById($ItemID)
        $Ctx.Load($Item)
        $Ctx.ExecuteQuery()

        #Get the Taxonomy Session
        $TaxonomySession = [Microsoft.SharePoint.Client.Taxonomy.TaxonomySession]::GetTaxonomySession($Ctx);
        $TaxonomySession.UpdateCache()
        $TermStore =$TaxonomySession.GetDefaultSiteCollectionTermStore()
        $Ctx.Load($TaxonomySession)
        $Ctx.Load($TermStore)
        $Ctx.ExecuteQuery()

        #Get the Term Group    
        $TermGroup = $TermStore.Groups.GetByName($TermGroupName)
        $Ctx.Load($TermGroup)

        #Get the termset
        $TermSet = $TermGroup.TermSets.GetByName($TermSetName)
        $Ctx.Load($TermSet)
        
        #Get the term
        $Term = $TermSet.Terms.GetByName($TermName) 
        $Ctx.Load($Term)
        $Ctx.ExecuteQuery()
       
        #sharepoint online powershell update managed metadata
        $Item[$TaxonomyFieldTitle] = $Term.Id.ToString()
        $Item.Update()
        $Ctx.ExecuteQuery()

        Write-host -f Green "Taxonomy Column Value has been updated successfully!"
     }
    Catch {
        write-host -f Red "Error updating Taxonomy Field Value!" $_.Exception.Message
   }

此脚本将给定的托管元数据列值更新为指定的术语。

简而言之，您可以使用术语 GUID 更新 MMS 字段！例如：$ListItem[“ManagedMetadataField”] =“6165a8c3-1e46-45de-abfe-2dc28dd1f8c6”

SharePoint Online：用于更新托管元数据的 PowerShell

或者，您也可以投射列并设置 MMS 字段值。这是一个示例（从第 52 行替换）：


#Get the Field
$Field = $List.Fields.GetByInternalNameOrTitle($TaxonomyFieldTitle)
$Ctx.Load($Field)
$Ctx.ExecuteQuery()

#Cast to Taxonomy Field
$TaxField = [Microsoft.SharePoint.Client.ClientContext].GetMethod("CastTo").MakeGenericMethod([Microsoft.SharePoint.Client.Taxonomy.TaxonomyField]).Invoke($Ctx, $Field)
$TaxFieldValue = New-Object Microsoft.SharePoint.Client.Taxonomy.TaxonomyFieldValue 
$TaxFieldValue.TermGuid = $Term.Id

#sharepoint online powershell to set managed metadata field value
$TaxField.SetFieldValueByValue($Item,$TaxFieldValue)
$Item.Update()
$Ctx.ExecuteQuery()

在 SharePoint Online 中使用 PowerShell 更新多值托管元数据列：

上述脚本使用单个值设置托管元数据字段。如何在启用“允许多个值”设置的情况下更新 MMS 列？ 


#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
Add-Type -Path "C:\Program Files\Common Files\microsoft shared\Web Server Extensions\ISAPI\Microsoft.SharePoint.Client.Taxonomy.dll"
 
#Set parameter values
$SiteURL="https://crescent.sharepoint.com/sites/Ops/"
$ListName="Projects"
$ItemID="1"
$TaxonomyFieldTitle="Region"

#Managed Metadata parameters
$TermGroupName="Regions"
$TermSetName="MENA"
$TermNames = @('UAE','Qatar')

Try { 
        #Get Credentials to connect
        $Cred= Get-Credential
        $Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)
 
        #Setup the context
        $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
        $Ctx.Credentials = $Credentials

        #Get the list and Item
        $List=$Ctx.web.Lists.GetByTitle($ListName)
        $Item = $List.GetItemById($ItemID)
        $Ctx.Load($Item)
        $Ctx.ExecuteQuery()

        #Get the Taxonomy Session
        $TaxonomySession = [Microsoft.SharePoint.Client.Taxonomy.TaxonomySession]::GetTaxonomySession($Ctx);
        $TaxonomySession.UpdateCache()
        $TermStore =$TaxonomySession.GetDefaultSiteCollectionTermStore()
        $Ctx.Load($TaxonomySession)
        $Ctx.Load($TermStore)
        $Ctx.ExecuteQuery()

        #Get the Term Group    
        $TermGroup = $TermStore.Groups.GetByName($TermGroupName)
        $Ctx.Load($TermGroup)

        #Get the termset
        $TermSet = $TermGroup.TermSets.GetByName($TermSetName)
        $Ctx.Load($TermSet)
        
        #Get All terms from the termset
        $Terms = $TermSet.GetAllTerms()
        $Ctx.Load($Terms)
        $Ctx.ExecuteQuery()

        $TermValues = @();
        #Get Each Term from the given Terms Array and form the Term String. E.g. "-1;#UAE|b3816a66-12d4-4232-f99e4620a;#-1;#Qatar|casae2c4-195-42d5-gb73ebcd5"
        ForEach($Term in $Terms)
        {
            ForEach($TermName in $TermNames)
            {
                If($TermName -eq $Term.Name)
                {
                    $TermValues += "-1;#" + $Term.Name + "|" + $Term.Id
                    $TermValuesString = $TermValues -join ";#"
                }
            }
        }

        #Get the Field to update
        $Field = $List.Fields.GetByInternalNameOrTitle($TaxonomyFieldTitle)
        $Ctx.Load($Field)
        $Ctx.ExecuteQuery()

        #Cast to Taxonomy Field
        $TaxField = [Microsoft.SharePoint.Client.ClientContext].GetMethod("CastTo").MakeGenericMethod([Microsoft.SharePoint.Client.Taxonomy.TaxonomyField]).Invoke($Ctx, $Field)

        #update managed metadata column powershell sharepoint online
        $TaxFieldValues = New-Object Microsoft.SharePoint.Client.Taxonomy.TaxonomyFieldValueCollection($Ctx, $TermValuesString, $TaxField)
        $TaxField.SetFieldValueByValueCollection($Item, $TaxFieldValues)
        $Item.Update()
        $Ctx.ExecuteQuery()

        Write-host -f Green "Taxonomy Column Value has been updated successfully!"
     }
    Catch {
        write-host -f Red "Error updating Taxonomy Field Value!" $_.Exception.Message
   }

PnP PowerShell 更新 SharePoint Online 中的托管元数据列

以下是如何使用 PnP PowerShell 向托管元数据列添加值：


#Config Variables
$SiteURL = "https://Crescent.sharepoint.com/sites/marketing"
$ListName = "Projects"
$ItemID = 1

#Set MMS Column value in: "Group|Termset|Parent|Child" format
$FieldValue = "Crescent|Deals Pipeline|Department|Accounts"

#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -Credentials (Get-Credential)

#Update Managed Metadata Column value using PowerShell
Set-PnPListItem -List $ListName -Identity $ItemID -Values @{"Department"= $FieldValue}

这将设置“部门”MMS 列值的值。

[玩转系统] SharePoint Online：使用 PowerShell 更新托管元数据字段值

如果您想要使用 PnP PowerShell 设置允许多个值的托管元数据列值，该怎么办？当然，只需将它们包装在一个数组中即可！


#Config Variables
$SiteURL = "https://crescent.sharepoint.com/sites/PMO"
$ListName = "Projects"
$ItemID = 1
 
#Set Multivalued Managed Metadata Column value in: "Group|Termset|Parent|Child" format
$FieldValue = @("PMO|Classification|IT","PMO|Classification|HR")
 
#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -Interactive

#Set Managed Metadata Column value using PowerShell
Set-PnPListItem -List $ListName -Identity $ItemID -Values @{"Department"= $FieldValue}

我们还可以使用 Set-PnpTaxonomyFieldValue cmdlet 设置托管元数据字段的值。例如。，


#Parameters
$SiteURL = "https://crescent.sharepoint.com/sites/PMO"
$ListName = "Projects"
$FieldInternalName = "Department"
$ItemID = 1

#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -Interactive

#Get the List Item
$ListItem = Get-PnPListItem -List $ListName -Id $ItemID 

#Set Managed Metadata Column value in: "Group|Termset|Parent|Child" format
Set-PnpTaxonomyFieldValue -ListItem $ListItem -InternalFieldName $FieldInternalName -TermPath 'People|Department|HR'

您还可以使用带有 -TermID 参数的术语 ID (GUID) 来更新字段值。同样，要更新具有多个值的托管元数据列，请使用：


#Set Multivalued Managed Metadata Column value in: @{"TermId1"="Label1";"TermId2"="Label2"} format
Set-PnpTaxonomyFieldValue -ListItem $ListItem -InternalFieldName $FieldInternalName -Terms @{"4f31bd74-d1cf-4318-bcbc-6e7b481fcce8"="Engineering";"4038e965-dbb8-4969-8783-02af0cbcbdfd"="HR"}
