Sitecore Code Editor 1.4 Preview

It's raining today here in Dallas which probably explains why I sound like I'm falling asleep in the video. Here's a preview of enhancements to Code Editor 1.4.

Reports with Sitecore PowerShell Extensions

I was trolling through the Sitecore Marketplace the other day and found this cool module for reporting about media library items called Unused Media Manager. I thought this would be a great example of how you can adapt code that would traditionally be written in C# and turn it into a simple script in Powershell.

Here's a quick example of where the new scripts appear within the Sitecore tree.

As you can see, SPE provides a reports folder where you can add scripts that will appear under Reporting Tools > PowerShell Reports.

I selected the Unused media items script which produced the following results:

The above window is produced by using the "Show-ListView" command.

	<#
	.SYNOPSIS
	Lists all media items that are not linked to other items.
	.NOTES
	Michael West
	#>
	# HasReference determines if the specified item is referenced by any other item.
	function HasReference {
	param(
	$Item
	)
	$linkDb = [Sitecore.Globals]::LinkDatabase
	$linkDb.GetReferrerCount($Item) -gt 0
	}
	<#
	Get-MediaItemWithNoReference gets all the items in the media library
	and checks to see if they have references. Each item that does not
	have a reference is passed down the PowerShell pipeline.
	#>
	function Get-MediaItemWithNoReference {
	$items = Get-ChildItem -Path "master:\sitecore\media library" -Recurse |
	Where-Object { $_.TemplateID -ne [Sitecore.TemplateIDs]::MediaFolder }
	foreach($item in $items) {
	if(!(HasReference($item))) {
	$item
	}
	}
	}
	# Setup a hashtable to make a more readable script.
	$props = @{
	InfoTitle = "Unused media items"
	InfoDescription = "Lists all media items that are not linked to other items."
	PageSize = 25
	}
	# Passing a hashtable to a command is called splatting. Call Show-ListView to produce
	# a table with the results.
	Get-MediaItemWithNoReference |
	Show-ListView @props -Property @{Label="Name"; Expression={$_.DisplayName} },
	@{Label="Updated"; Expression={$_.__Updated} },
	@{Label="Updated by"; Expression={$_."__Updated by"} },
	@{Label="Created"; Expression={$_.__Created} },
	@{Label="Created by"; Expression={$_."__Created by"} },
	@{Label="Path"; Expression={$_.ItemPath} }
	Close-Window
