How to get value from the MultiList Field and Get Path to Tag Repository

Question

I have a little bit of confusion regarding the Multilist Field in Sitecore. Basically, I want to get all of the selected MultiList Field in PowerShell to do stuff with them.

Is it possible to make those values in array?

Here is the code so far:

$props = @{
    Title = "Get All Media Items by Tag"
    Description = "Get all Media items by Tag"
    OkButtonName = "Run Report"
    CancelButtonName = "Cancel"
    Parameters = @(
        @{ Name = "TagName"; Title = "Tag Name"; Editor = "multilist"; Source = "/sitecore/system/Settings/Buckets/TagRepository/2021/12/16/14/36" }
        @{ Title = "Note"; Value = "Select Tags you need for the Images from the Tag Repository"; Editor = "info" }
    )
}

$result = Read-Variable @props
if($result -ne "ok") {
    Close-Window
    Exit
}

The path for the Tag Repositoy is bucket, as you know. How to get also path for that? Source = "/sitecore/system/Settings/Buckets/TagRepository/2021/12/16/14/36" }

And this is the picture showing what this code does:

Is there any way to get those selected values and make them in array, or they are in array by default?

I personally think maybe $TagName.Values would do the trick, or something like that

You are correct with your approach. You just have a typo. Use Name = "TagNames" instead of Name = "TagName" in your props. Then you can use $TagNames:

$props = @{
    Title = "Get All Media Items by Tag"
    Description = "Get all Media items by Tag"
    OkButtonName = "Run Report"
    CancelButtonName = "Cancel"
    Parameters = @(
        @{ Name = "TagNames"; Title = "Tag Name"; Editor = "multilist"; Source = "/sitecore/system/Settings/Buckets/TagRepository/2021/12/16/14/36" }
        @{ Title = "Note"; Value = "Select Tags you need for the Images from the Tag Repository"; Editor = "info" }
    )
}

$result = Read-Variable @props

if($result -ne "ok") {
    Close-Window
    Exit
}

foreach ($tag in $TagNames) {
    # ... do whatever you need with your tag
}
