How can I use PowerShell to upload a list template (stp file)?

Question

I need to script the creation of data in SharePoint, and part of this requires that I upload a slide library list template using PowerShell. Is this possible?

Answer 1

You can cheat using Webdav :

Copy-Item 'yourTemplate.stp' '\\yourspwebapp\DavWWWRoot\sites\yoursitecoll\_catalogs\lt'

[edit] according your comment, here is a way to find the correct url.

1. Navigate using the browser to the list template catalog list. The link should look like : http://yourwebapp/sites/yoursitecoll/_catalogs/lt
2. as it is a document library, you can, from the ribbon's tab "Library", click on Open in windows explorer
3. an windows explorer windows pop ups, but with "http://" address.
4. Right click in the window, click properties, and you will find the actual address.

This worked for me, with a SP application having a custom AAM (yourspwebapp is not the hostname, but a virtual hostname). I checked locally... did you want to do this remotely ?

[Edit2] if installing Webdav is an issue on your server, you can use the following snippet :

$wc = new-object System.Net.WebClient
$file = (Get-Item '.\New Text Document.txt')
$dest = "http://yourspwebapp/sites/yoursitecoll/_catalogs/lt"
$wc.UseDefaultCredentials = $true
$wc.UploadFile($dest +"/" + $file.Name, $file.FullName)

Or you can use the sp OM, as Jimmarq suggests

WebDav might work for others, but I found a way to do it using the SharePoint object model. (I used the folders indicated by Steve B--thanks.)

$site = get-spsite "http://myteam.lab/sites/team"
$web = $site.OpenWeb()
$spFolder = $web.getfolder("List Template Gallery")
$spfilecollection = $spfolder.files
$file = get-item c:\temp\MyTemplate.stp
$spfilecollection.Add("_catalogs/lt/MyTemplate.stp", $file.OpenRead(), $true)

I saw the template in the "Create" page, so everything seemed to work ok.
