Sitecore Powershell Extensions not returning field source value

Question

I'm trying to write a simple Powershell script that finds all General Link fields and outputs the value of their Source field.

$fields = Get-ChildItem -Path "master://sitecore/templates/user defined" -Recurse | Where-Object { $_.TemplateName -eq "Template field" -and $_.Type -eq "General Link" }

foreach ($field in $fields) {
    Write-Host "Name: $($field.Name)"
    Write-Host "Source: $($field.Source)"
    Write-Host
}

Whenever I run it, however, the value from the Source field is empty for all returned items.

I've confirmed that it is populated in at least some of the cases, but it never shows up in the report. I've tried several variations to get the value, too:

$fields | Show-ListView -property `
    @{ Name="Path"; Expression={$_.Paths.Path} },
    @{ Name="Source"; Expression={$_.Source} },
    @{ Name="Source With Quotes"; Expression={$_."Source"} }

Versions

• Sitecore version: 8.1 Update 3
• Sitecore PowerShell Extensions version: 5.0.0.42513

Answer 1

There is no Source property on Sitecore.Data.Items.Item class.

You need to get Source field value e.g. like this:

foreach ($field in $fields) {
    Write-Host "Name: $($field.Name)"
    Write-Host "Source: $($field._.Source.Value)"
    Write-Host
}

Answer 2

The issue is that the Source field is of type Template Field Source, which seems to not automatically emit a value if you simply access the field directly on the item ($field.Source).

Instead, you must get the field and get the value from that field:

$field.Fields['Source'].Value
