Powershell to run 2 workflows

Question

I have a Powershell that runs 2 workflows. The first workflow is on every list item and the second simply sends an email to let people know that the Powershell ran successfully.

I'm getting errors when I try to run the single workflow

PowerShell

  $web = Get-SPWeb -Identity "http://portal.com/sites/it" 
$manager = $web.Site.WorkFlowManager   
$list = $web.Lists["Certificate Tracking"]

$assoc = $list.WorkflowAssociations.GetAssociationByName("Certificate Notification","en-US")
$assoc.AllowAsyncManualStart = $true
$assoc.AllowManual = $true

$emails = $list.WorkflowAssociations.GetAssociationByName("Status Update","en-US")
$emails.AllowAsyncManualStart = $true
$emails.AllowManual = $true

$view = $list.Views["All Items"] #All Items
$items = $list.GetItems($view)  

$data = $assoc.AssociationData
$emData = $emails.AssociationData

$count = 0

foreach ($item in $items) {
 $wf = $manager.StartWorkFlow($item,$assoc,$data) 
}
$em = $manager.StartWorkFlow($item,$emails,$emData)

$web.Dispose()

Error

 Exception calling "StartWorkflow" with "3" argument(s): ""

Answer 1

Try using this code

$web = Get-SPWeb -Identity "http://portal.com/sites/it" 
$manager = $web.Site.WorkFlowManager   
$list = $web.Lists["Certificate Tracking"]

$assoc = $list.WorkflowAssociations.GetAssociationByName("Certificate Notification","en-US")
$assoc.AllowAsyncManualStart = $true
$assoc.AllowManual = $true

$emails = $list.WorkflowAssociations.GetAssociationByName("Status Update","en-US")
$emails.AllowAsyncManualStart = $true
$emails.AllowManual = $true

$view = $list.Views["All Items"] #All Items
$items = $list.GetItems($view)  

$data = $assoc.AssociationData
$emData = $emails.AssociationData

$count = 0

foreach ($item in $items) {

    $wf = $manager.StartWorkFlow($item,$assoc,$data) 
    $em = $manager.StartWorkFlow($item,$emails,$emData)

}


$web.Dispose()

Answer 2

You are getting error for this line $em = $manager.StartWorkFlow($item,$emails,$emData)

This is because scope for parameter $item is inside for loop only. And you are passing it outside for loop where it is undefined.

Either you can call workflow inside for loop

foreach ($item in $items) {
    $wf = $manager.StartWorkFlow($item,$assoc,$data) 
    $em = $manager.StartWorkFlow($item,$emails,$emData)
}

Or you can directly send mail using Powershell.

You can get some examples on google to send mail using Powershell.

Here is one reference: Send mail using Powershell

$web = Get-SPWeb -Identity "http://portal.com/sites/it" 
$manager = $web.Site.WorkFlowManager   
$list = $web.Lists["Certificate Tracking"]

$assoc = $list.WorkflowAssociations.GetAssociationByName("Certificate Notification","en-US")
$assoc.AllowAsyncManualStart = $true
$assoc.AllowManual = $true

$emails = $list.WorkflowAssociations.GetAssociationByName("Status Update","en-US")
$emails.AllowAsyncManualStart = $true
$emails.AllowManual = $true

$view = $list.Views["All Items"] #All Items
$items = $list.GetItems($view)  

$data = $assoc.AssociationData
$emData = $emails.AssociationData

$errorCount = 0

Try
{
    foreach ($item in $items) {
    $wf = $manager.StartWorkFlow($item,$assoc,$data) 
    }
}
Catch [system.exception]
{
   #send email or log to file system
   $errorCount = 1
}
Finally
{
   if ($errorCount -eq 0)
   {
      $em = $manager.StartWorkFlow($item,$emails,$emData)
   }
}
