Powershell Where-Object inserting array - arrays

Question

I'm trying to build a Powershell script that can filter the information from a CSV file. But I'm having problems when using an array as one of parameters.
This command works when I import the CSV file and type it in manually:
$data |
where-object {
(
$_.PackageAffected -eq "BslEqipWebPkg" -or
$_.PackageAffected -eq "BslIDealAdminPkg" -or
$_.PackageAffected -eq "ALL"
) -and (
$_.ENV -eq "PROD" -or $_.ENV -eq "ALL"
)
} |
select-object -property 'major step id','minor step id','PackageAffected',ENV,detail |
format-table -autosize
I am trying to build the $_.PackageAffected line up using an array.
Here is the code so far (that isn't working):
$packageList = "`$_.PackageAffected -eq `"" + $package[0] + "`" -or"
for ($element=1; $element -lt $package.count; $element++) {
$packageList = $packageList + " `$_.PackageAffected -eq `"" + $package[$element] + "`" -or"
}
$packageList = $packageList + " `$_.PackageAffected -eq `"ALL`""
$data |
where-object{($packageList) -and ($_.ENV -eq $environment -or $_.ENV -eq "ALL")} |
select-object -property 'major step id','minor step id','PackageAffected',ENV,detail |
format-table -autosize
$packageList
At the bottom where I've put $packageList it displays onscreen the string I would expect to see, which is:
$_.PackageAffected -eq "pkgName1" -or $_.PackageAffected -eq "pkgName2" -or $_.PackageAffected -eq "ALL"
But when I view the table after it's been run, there are no filters on it for the PackageAffected.
My suspicions are that I've converted the command into a string and when it runs, Powershell doesn't recognise it as a command.

You need to evaluate the expression. This can be done with Invoke-Expression, e.g.
Invoke-Expression $packageList
In the context of your code, this would be:
$data |
where-object{(Invoke-Expression $packageList) -and ($_.ENV -eq $environment -or $_.ENV -eq "ALL")} |
select-object -property 'major step id','minor step id','PackageAffected',ENV,detail |
format-table -autosize
