Updating PSObject hash table in loop - powershell

Question

Here is a part code of uploading data by FTP
foreach ($line in $FTPServer)
{
Start-Transcript -Path $results
Write-Host -Object "ftp url: $line"
If (Test-Connection $line -Count 1)
{
Set-FTPConnection -Credentials $FTPCredential -Server $line -Session MySession -UsePassive -ErrorAction SilentlyContinue
$Session = Get-FTPConnection -Session MySession
if($session.UsePassive -eq "True"){$connect="OK"}
else{$connect="!!!-FAIL-!!!"}
foreach ($item in (Get-ChildItem .\Upload))
{
Write-Host -Object "Uploading $item..."
$Send= Add-FTPItem -Session $Session -Path $FTPPlace -LocalPath .\Upload\$item -Overwrite -ErrorAction SilentlyContinue
if($Send.Name -eq $item.Name){$Rec="OK"}
else{$Rec="!!!-FAIL-!!!"}
$array = $line, $item, $connect, $Rec
$FailTable=New-Object -TypeName PSObject -Property ([ordered]#{"FTP Server"=$array[0]; "File"=$array[1];"Connected"=$array[2];"Uploaded"=$array[3]})
$FailTable|Out-File -Append '.\stats.txt'
}
Stop-Transcript
} Else {"$line">> .\DownServers.txt}
}
$Failtable is a hash-table that stores ip of FTP server ($line), name of uploaded file ($item), status if connected ($connect) and upload status ($Rec). The hash-table is piped to file .\stats.txt The problem is in every iteration to .\stats.txt are saved headers like that:
FTP Server File Connected Uploaded
---------- ---- --------- --------
192.168.1.1 ConfigurationDivide.xml OK !!!-FAIL-!!!
FTP Server File Connected Uploaded
---------- ---- --------- --------
192.168.1.1 test.txt OK !!!-FAIL-!!!
So I need that to be one under another and autosized like that:
FTP Server File Connected Uploaded
---------- ---- --------- --------
192.168.1.1 ConfigurationDivide.xml OK !!!-FAIL-!!!
192.168.1.1 test.txt OK !!!-FAIL-!!!
I tryed to put hash-table declaration $FailTable=New-Object -TypeName PSObject -Property ([ordered]#{"FTP Server"=$array[0]; "File"=$array[1];"Connected"=$array[2];"Uploaded"=$array[3]}) before loops and then- in the loops add values ($line, $item,...), but there aren't in hashtable .add method.

Ok, different answer :)
Try this:
$FailTable = #()
$spam = New-Object PSObject
$spam | Add-Member -type NoteProperty -Name 'FTP Server' -Value ""
$spam | Add-Member -type NoteProperty -Name 'File' -Value ""
$spam | Add-Member -type NoteProperty -Name 'Connected' -Value ""
$spam | Add-Member -type NoteProperty -Name 'Uploaded' -Value ""
$FailTable += $spam
$FailTable | Out-File -Append '.\stats.txt'
foreach ($line in $FTPServer)
{
Start-Transcript -Path $results
Write-Host -Object "ftp url: $line"
If (Test-Connection $line -Count 1)
{
Set-FTPConnection -Credentials $FTPCredential -Server $line -Session MySession -UsePassive -ErrorAction SilentlyContinue
$Session = Get-FTPConnection -Session MySession
if($session.UsePassive -eq "True"){$connect="OK"}
else{$connect="!!!-FAIL-!!!"}
foreach ($item in (Get-ChildItem .\Upload))
{
Write-Host -Object "Uploading $item..."
$Send= Add-FTPItem -Session $Session -Path $FTPPlace -LocalPath .\Upload\$item -Overwrite -ErrorAction SilentlyContinue
if($Send.Name -eq $item.Name){$Rec="OK"}
else{$Rec="!!!-FAIL-!!!"}
$spam = New-Object PSObject
$spam | Add-Member -type NoteProperty -Name 'FTP Server' -Value $line
$spam | Add-Member -type NoteProperty -Name 'File' -Value $item
$spam | Add-Member -type NoteProperty -Name 'Connected' -Value $connect
$spam | Add-Member -type NoteProperty -Name 'Uploaded' -Value $Rec
$FailTable += $spam
$FailTable | Select-Object -Last 1 | Format-Table -HideTableHeaders | Out-File -Append '.\stats.txt'
}
Stop-Transcript
} Else {"$line">> .\DownServers.txt}
}

You need to have FailTable created outside the loop, you are creating and appending an entire new PSCustomObject each loop to the file.
try implementing this:
$FailTable = #()
#Example loop
for($i =0;$i -lt 5; $i++){
#Inside the loop add new object to the array
$failTable += #{"FTPServer"=$i;"File"=$i;"Connected"=$i;"Uploaded"=$i}
}
#foreach hashmap in the array cast to a PSCustomObject (which gives you the headers you want)
#and then Select-Object The order you want them in.
$FailTable.foreach{[PSCustomObject]$_} | Select-Object "FTPServer", "File","Connected", "Uploaded" | Out-file test.txt
Edit:
PowerShell v2+ compatible version:
$FailTable = #()
$objTable = #()
#Example loop
for($i =0;$i -lt 5; $i++){
#Inside the loop add new object to the array
$failTable += #{"FTPServer"=$i;"File"=$i;"Connected"=$i;"Uploaded"=$i}
}
#foreach hashmap in the array cast to a PSCustomObject (which gives you the headers you want)
#and then Select-Object The order you want them in.
foreach($fail in $FailTable){
$objTable += New-Object -TypeName PSCustomObject -Property $fail
}
$objTable | Select-Object "FTPServer", "File","Connected", "Uploaded" | Out-file test.txt
