Function not processing every step - powershell

Question

The below snippet will jump to the correct function "ORD_LOG_PROCESS", it will CD to the path, but it will not store the variables after that. $ordfiles and every variable after that do not store. There is one file in the $ordlogpath directory, and if I do (gci $ordlogpath |% {$_.name}) at the shell it works, but via the script for some reason it will not store.
$ordlogpath = "C:\test_environment\ORD_REPO\ORD_LOGS\"
$ordlogexist = gci "C:\test_environment\ORD_REPO\ORD_LOGS\*.log"
FUNCTION ORD_LOG_PROCESS
{
cd $ordlogpath
$ordfiles = (gci $ordlogpath |% {$_.name})
FOREACH ($ordfile in $ordfiles)
{
$ordlogimport = Import-Csv $ordfile
$ordloggrep = $ordfile
exit
}
}
FUNCTION NO_FILES
{
write-host "NO FILES TO PROCESS"
EXIT
}
IF (!$ordlogexist)
{
NO_FILES
}
else
{
ORD_LOG_PROCESS
}

Answer 1

If you declare variables inside a function, they will be local to that function. That means that the variables do not exist outside the function.
But then.. why use functions like this at all?
Can't you simply do something like below?
$ordlogpath = "C:\test_environment\ORD_REPO\ORD_LOGS\*.log"
if (!(Test-Path -Path $ordlogpath)) {
Write-Host "NO FILES TO PROCESS"
}
else {
Get-ChildItem -Path $ordlogpath -File | ForEach-Object {
$ordlogimport = Import-Csv $_.FullName
# now do something with the $ordlogimport object,
# otherwise you are simply overwriting it with the next file that gets imported..
# perhaps store it in an array?
# it is totally unclear to me what you intend to do with this variable..
$ordloggrep = $_.Name
}
Write-Host "The log name is: $ordloggrep"
Write-Host
Write-Host 'The imported variable ordlogimport contains:'
Write-Host
$ordlogimport | Format-Table -AutoSize
}
