I’m sure everyone has used the Portal Site Connection settings in SharePoint to add a top-level portal site URL to the breadcrumb. I use it frequently to make sure that all site collections in a web application have a breadcrumb link to the top level/root site collection; however, until today I hadn’t put any thought into making a PowerShell Function to do this automagically to a single site collection or multiple site collections using PowerShell.

It was VERY easy to convert one of my many PowerShell Functions to accomplish this goal, and I started with something simple like:

$site = Get-SPSite http://intranet
$site.PortalUrl = "http://test"
$site.PortalName = "Test Site"
$site.Dispose()

Pretty simple, and certainly effective for a single site – however, I’m always thinking about bigger and better things. 🙂

By adding some logic, an if/else statement and a few parameters; I turned it into an advanced function which can either be used to set a single site collection or all site collections within a web application. Here’s the whole thing:

function Set-SPPortalSiteUrl {
<#
.Synopsis
	Use Set-SPPortalSiteUrl to set the Portal Site Connection Url using PowerShell.
.Description
	This advanced PowerShell function sets the PortalUrl Property of an SPSite Object or multiple SPSites in a SharePoint Web Application
	specified in the -Url parameter.
.Example
	C:\PS>Set-SPPortalSiteUrl -PortalWebAddress http://intranet -PortalName "Intranet Home" -Url http://intranet/hr
	This example sets the Portal Site Connection to http://intranet, with a name of Intranet Home on the http://intranet/hr Site Collection.
.Example
	C:\PS>Set-SPPortalSiteUrl -PortalWebAddress http://intranet -PortalName "Intranet Home" -Url http://intranet -AllSiteCollections
	This example sets the Portal Site Connection to http://intranet, with a name of Intranet Home on the entire http://intranet Web Application.
.Notes
	This function uses an SPSite Object to set the PortalUrl and PortalName properties of one or more SharePoint Site Collections.

		$site.PortalUrl = $PortalWebAddress
		$site.PortalName = $PortalName
		$site.Dispose()
		}

	$AllSites = Get-SPSite -Identity $Url

	$AllSites.PortalUrl = $PortalWebAddress
	$AllSites.PortalName = $PortalName
	$AllSites.Dispose()
	}
Stop-SPAssignment -Global
}

Happy PowerShelling!
