So I have powershell code to upload a palette file to my themes gallery but I cannot seem to figure out how to create the composed look in the composed look gallery using the link to my uploaded theme in sharepoint 2016/2013 in powershell, any suggestions?

Here is my current code:

If(!(Get-PSSnapin Microsoft.SharePoint.PowerShell -ea 0)){
Write-Progress -Activity "Loading Modules" -Status "Loading Microsoft.SharePoint.PowerShell"
   Add-PSSnapin Microsoft.SharePoint.PowerShell
   }

cls

$web = get-spweb http://test.site.com

<# Create composed look start #>
foreach($site in $web.Site.Allwebs)
{

    <# Upload Palette to Themes Gallery in rootsite Start #>
    try
    {
    $rootWeb = get-spweb $site.Site.RootWeb.Url

    $DocLibName = “_catalogs/theme” #Themes Library Name
    $FilePath = “C:\temp\colorPalette.spcolor” #Local path to palette file

    $List = $rootWeb.GetFolder($DocLibName) 
    $Files = $List.Files

    $FileName = $FilePath.Substring($FilePath.LastIndexOf("\")+1)

    # Load the file into a variable 
    $File= Get-ChildItem $FilePath

    # Upload it to SharePoint 
    $Files.Add($DocLibName +"/" + $FileName,$File.OpenRead(),$false)
    }
    catch
    {
    #
    }
    <# Upload Palette to Themes Gallery in rootsite End #>

    <# Verify Site not root site Start #>
    if($site.Url -ne $site.Site.RootWeb.Url)
    {
    $paletteUrl = $site.Site.RootWeb.Url + "/_catalogs/theme"
    $paletteUrl

    $compositeLookGallery = $site.GetCatalog(124)
    #$site.Load($compositeLookGallery)
    $spContext = New-Object Microsoft.SharePoint.Client.ClientContext($site.Url);
    }
    <# Verify Site not root site End #>
}
<# Create composed look End #>

  • Sorry, I have a .spcolor file and not a .thmx file so this won't help me :( – The Inexperienced Gamer Oct 9 '17 at 15:12
  • In the 2. region you are going to create a theme. Having a spcolor file is enough to run the code snippet if($SpListItems1.Count -eq 0) { $NewThemeItem = $SpList.AddItem() $NewThemeItem["Name"] = $ThemeName $NewThemeItem["Title"] = $ThemeName $NewThemeItem["MasterPageUrl"] = "$RelativeUrl$MasterPagePartUrl$Masterpage" $NewThemeItem["ThemeUrl"] = $ThemeUrlColor $newThemeItem["FontSchemeUrl"] = $ThemeUrlFont $NewThemeItem["DisplayOrder"] = 121 $NewThemeItem.Update() } – Majo Son Oct 9 '17 at 15:25
  • Thanks! Once I get my dev environment back up I will test and follow up. – The Inexperienced Gamer Oct 9 '17 at 15:30
  • So I got that to work but if I go to theme and set it back to "Inherit from parent" the site breaks/works but is all jumbled. Thoughts? – The Inexperienced Gamer Oct 11 '17 at 19:02
  • Disregard previous comment, the issue was on our end. Thanks and I have marked your response as the answer. – The Inexperienced Gamer Oct 11 '17 at 19:21
