Detailed Description

The cmdlet manipulates link to a specific item. The target item can be provided as an Item object or through Path/ID. it does not modifies the item itself but rather other items that link to it. If the -RemoveLink parameter is used the link will be removed rather than modified. To deliver more fine grained filtering you can provide ItemLink using the -Link parameter. You can obtain ItemLinks using Get-ItemReferrer or Get-ItemReference cmdlets. Consult Examples for specific use cases of each approach.

Examples

EXAMPLE 1

This example covers global operations

Assuming Sitecore PowerShell Extensions 4.2 or newer is installed Assuming your Home has an "Image" field of type "Image" Assuming you have second item next to Home called Home2 that has an "Image" field of type "Image"

$coverImage = Get-Item 'master:\media library\Default Website\cover'
$scLogoImage = Get-item 'master:\media library\Default Website\sc_logo'
Write-Host "`nReset 'home', 'child' and 'home2' to link to 'cover'- 3 items" -Foreground Magenta
(Get-item master:\content\home).Image = $coverImage
(Get-item master:\content\Home\child).Image = $coverImage
(Get-item master:\content\home2).Image = $coverImage
Get-ItemReferrer -Item $coverImage
Write-Host "`nRelinking all instances of 'cover' image to 'sc_logo'" -Foreground Yellow
$coverImage | Update-ItemReferrer -NewTarget $scLogoImage
Write-Host "`n'cover' should no longer have links leading to it - 0 items " -Foreground Red
$coverImage | Get-ItemReferrer
Write-Host "`n'sc_logo' should now be linked from all - 3 items" -Foreground Green
$scLogoImage | Get-ItemReferrer
Write-Host "`nRemoving links to 'sc_logo' from all items" -Foreground Yellow
$scLogoImage | Update-ItemReferrer -RemoveLink
Write-Host "`n'sc_logo' should have no links to it - 0 items" -Foreground Red
$scLogoImage | Get-ItemReferrer

EXAMPLE 2

This example covers more fine-grained filtered approach to removing links

Assuming Sitecore PowerShell Extensions 4.2 or newer is installed Assuming your Home has an "Image" field of type "Image" Assuming you have second item next to Home called Home2 that has an "Image" field of type "Image"

$coverImage = Get-Item 'master:\media library\Default Website\cover'
$scLogoImage = Get-item 'master:\media library\Default Website\sc_logo'
Write-Host "`nReset 'home', 'child' and 'home2' to link to 'cover'- 3 items" -Foreground Magenta
(Get-item master:\content\home).Image = $coverImage
(Get-item master:\content\Home\child).Image = $coverImage
(Get-item master:\content\home2).Image = $coverImage
Get-ItemReferrer -Item $coverImage
Write-Host "`nRemove links to the 'cover' image from all items under 'master:\content\home'" -Foreground Yellow
Get-ChildItem master:\content\home -WithParent -Recurse | # get items under home
Get-ItemReference -ItemLink | # get all items that they are refering to
? { $_.TargetItemID -eq $coverImage.ID } | # filter only references to $coverImage
Update-ItemReferrer -RemoveLink # remove links
Write-Host "`n'cover' should have 1 link leading from 'home2'" -Foreground Green
$coverImage | Get-ItemReferrer
