PowerShell script to start SharePoint workflow
# For MOSS 2007 compatibility
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")
#Region MOSS2007-CmdLets
Function global:Get-SPSite()
{
Param( [Parameter(Mandatory=$true)] [string]$SiteCollURL )
if($SiteCollURL -ne '')
{
return new-Object Microsoft.SharePoint.SPSite($SiteCollURL)
}
}
Function global:Get-SPWeb()
{
Param( [Parameter(Mandatory=$true)] [string]$SiteURL )
$site = Get-SPSite($SiteURL)
if($site -ne $null)
{
$web=$site.OpenWeb();
}
return $web
}
#EndRegion
#Get the Web
$web = Get-SPWeb "http://sharepoint.company.com"
#Get the List
$list=$web.Lists["Review Documents"]
#Get Workflow Manager
$WFManager=$Web.site.WorkFlowManager
#Get the specifi workflow, Associated with the list
$WFAssociation = $list.WorkFlowAssociations | where {$_.Name -eq "Approval Workflow"}
#Start Workflow on Each List Item
foreach ($item in $list.Items)
{
$WFManager.StartWorkFlow($item,$WFAssociation,$WFAssociation.AssociationData)
write-host "Started Workflow on $($item.Name)"
}
$web.Dispose()
