Doesn't work PowerShell script

Question

I try to use following PowerShell script in iLoveSharePoint.PowerEventReceiver

function ItemAdding
{
    $url = 'http://win-4cc5e89pifo:1234/docs/'
    $web = Get-SPWeb -webUrl $url
    $list = $web.Lists['CodeBehind']

    foreach ($item in $list)
    {
        if ($item.Title -eq $properties.AfterProperties["Title"])
        {
            $properties.Status = [Microsoft.SharePoint.SPEventReceiverStatus]::CancelWithRedirectUrl

            $properties.RedirectUrl = [Microsoft.SharePoint.Utilities.SPUrlUtility]::CombineUrl($properties.Web.Url,"/SitePages/step1.aspx?p=1")

            break
        }   
    }
}

Where is an error?

Answer 1

试试这个CombineUrl($web.Url,或

$httpContext.Response.Redirect("somewhere/to/go",$true);

Answer 2

There seems to be no named parameter -webUrl for the Get-SPWeb Cmdlet.

Try

$web = Get-SPWeb $url

in your script instead.

Also check if $web isn't null.
