Hey folks,

Trying to validate that a date entered is correct using powershell. So far this is what I have:

function ValidateDate
{
    param([string]$date=$_)
    $result = 0
    [bool]$valid = $false
    if (!([DateTime]::TryParse($date, [ref]$result))){
        Write-Host "Your date $date was invalid. Please try again."
        $date = Read-Host "Please enter the date with the following format mm/dd/yy: "
        ValidateDate $date
    }
    else{$valid = $true}
    Return $valid
}

When running the script, I enter a wrong date on purpose, it prompts me to revise the date, and then it should return a true value once the date is correct. Unfortunately this is the output I get:

PS C:\Users\bvandermark> ValidateDate 6/51/12
Your date 6/51/12 was invalid. Please try again.
True
False

Not sure why the false is there as well. Any thoughts?

Never mind. Resolved this on my own.

The trick was to include the Return $valid in the else statement.

function ValidateDate
{
    param([string]$date=$_)
    $result = 0
    [bool]$valid = $false
    if (!([DateTime]::TryParse($date, [ref]$result))){
        Write-Host "Your date $date was invalid. Please try again."
        $date = Read-Host "Please enter the date with the following format mm/dd/yy: "
        ValidateDate $date
    }
    else{
        $valid = $true
        Return $valid
    }
}
