User Input captured, Incrementing until condition met

jonfollowell2 · 2019-06-25T13:31:52.000Z

Hello All,

I am just starting my voyage into Powershell and one of the things I am currently trying to do is write a Script to create a MS Team. I have created plenty of teams already from powershell but I want to make it so anyone in my team even student workers with no know how could just run my script.

Capturing simple variables like the name, description, owner and such have been easy. The part I am trying to figure out is how to capture all of the members to be added.

In my mind I see something roughly along the lines of this. I know it won’t work I just don’t know how to increment a user input variable until a condition is met and capture each as a unique variable that I can call later.

$member = (read-host "What is the email address of the member you want to add?")
$moreUsers = (read-host "Do you want to add more users? Yes or No?")
while ($moreUsers -notlike "no")
 {
         increment something here on $member for capture
         $member2 = (read-host "What is the email address of the member you want to add?")
         $moreUsers = (read-host "Do you want to add more users? Yes or No?")
    }

If anybody could point me to a good primer on capturing user input like this that would increment until a condition would be met that would be great or give me a hand on making that butchered nonsense above into something working. Any tips are welcome. I am enjoying the flexibility with powershell but I have a long ways to go. Thanks

I mean what you suggest would work, you could write a little DOS menu.

You can use a For loop or While loop to repeat commands while the conditions are true.

about For - PowerShell

Describes a language command you can use to run statements based on a conditional test.

You can use the ++ operator to increment integers. For example:

$Integer = 0
$Integer++

So again forgive my ignorance here. If I use an increment command like you suggest and my variable in this is $member. Let’s say they wanted to add seven members until they answered No in my While loop. I could later call each iteration that ran on the increment command as a unique variable later? How would I call each member variable in that circumstance?

$member1, $member2, $member3 and so on?

This is possible but complex.

You could use Read-Host to ask if the user wants to add multiple members and use an If statement to check it. If the user wants to add multiple members, ask how many, validate that input is an integer, and send it to a custom function that uses the integer as the end limit in a For-Loop.

Function Add-MultipleMembers {
    param (
        [int]$Count
    )
    For ($Integer = 0; $Integer -lt $Count; $Integer++) {
        New-Variable -Name "Member$Integer" -Scope Global -Value <value>
        <commands to add members>

    }
}

$MultipleMembers = Read-Host -Prompt "Do you want to add multiple members? (y/n)"
If ($MultipleMembers -eq 'y') {
    $Number = Read-Host -Prompt "Enter integer of how many members do you want to add. (Example: 7)"

Add-MultipleMembers -Count $Number
}

So I made a pivot with how I was making my script. The feedback here was helpful. Thanks for your time!

Also yes it does work. I already see how I can vastly improve it and make it more efficient but for a first project I am happy.

Till next time. Stay spicey.
