Implementing User Input with Read-Variable in SPE

The Sitecore PowerShell Extensions (SPE) module speeds up the delivery of Sitecore solutions by helping you automate tasks with interactive tools for your custom scripts.

In this post, I’ll share a very useful SPE command, Read-Variable, which is a powerful, yet simple way of adding user input to SPE scripts.


The Read-Variable function in SPE allows a user to input the necessary parameters in a customizable dialog box to run your script. (Check out the full Read-Variable documentation here.)

You can create one or more PowerShell hash tables to specify each of the parameters that you pass to the Read-Variable function:

$dialogParams = @{
    Title = "Dialog title"
    Description = "Description under title"
    OkButtonName = "Execute"
    CancelButtonName = "Close"
    Parameters = @(
            Name = "textField"
            Title = "Text Field"
$dialogResult = Read-Variable @dialogParams

If you run this code snippet in the PowerShell ISE, you will get the following dialog:

Dialog Box

To determine if the user has pressed the "Ok" button ("Execute" in the example) or the "Cancel" button ("Close" in the example), just test the dialog result variable ($dialogResult in the example) to see if it equal to "ok":

if ($dialogResult -ne "ok") {

To read the user input (which is the purpose of this mechanism), take note of each of the Parameters' "Name" value. For the example, we have a single Parameter named "textField". We refer to the entered value by using it like any other PowerShell variable. In this example we use $textField:

Write-Host "Value entered by user: " $textField

The return type of the Parameter will depend on the editor that you used for it. In this example, the editor is a simple text box, so you will get a string for $textField. If you use other editors like a droplist, you can get a Sitecore Item object, or an array of Items if using multi-list editors. We will talk about Parameter Editors in my next post.

Finally, you should always close the Script window after your script has finished running. Make sure to end your scripts with the following sentence:


This will ensure that the "Running script" dialog that appears when running a custom script from the Sitecore interface (outside of the PowerShell ISE) will automatically close.
