Powershell Rename files if name contains <string> - powershell

Question

I'm trying to prepend a PatientOrderNumber to the name of files in a directory if the file name includes a unique ID from my CSV file. I've tried the -like and -contains parameters and have not been successful.
here is my code:
$csvPath = "C:\Users\dougadmin28\Desktop\Test\1bs4e.csv"
## Variable to hold path of Files that need to be renamed ##
$filePath = "C:\Users\dougadmin28\Desktop\Node Modify File Name App\pdfs"
$csv = Import-Csv $csvPath #| Select-Object -Property PatientOrderNumber, FileID, DocumentID, LastName, FirstName|Export-Csv 'C:\Users\dougadmin28\Desktop\Node Modify File Name App\documents.csv'
$files = Get-ChildItem $filePath
foreach ($item in $csv){
foreach($file in $files) {
if($file.FullName -contains '*$item.DocumentID*') {
Rename-Item $file.FullName -NewName "$($item.PatientOrderNumber+"_"+($item.FileID)+'_'+($item.DocumentID)+'_'+($item.LastName)+'_'+($item.FirstName)+($file.extension))"
}#End forEach
}#End if
} #End forEach```

Answer 1

tl;dr
Instead of:
$file.FullName -contains '*$item.DocumentID*' # WRONG
use:
$file.FullName -like "*$($item.DocumentID)*"
Note the use of " instead of ' and the $(...) around the property-access expression.
As for what you tried:
$file.FullName -contains '*$item.DocumentID*'
-contains tests array membership of the RHS in the array-valued LHS, it doesn't perform substring matching.
See this answer for the difference between PowerShell's -contains operator and the String.Contains() .NET method.
'...' strings are taken literally (verbatim), so no expansion (interpolation) is performed; "..." (expandable strings) must be used for string interpolation.
See about_Quoting_Rules for documentation about PowerShell's string-literal types.
Inside an expandable string, only simple variable references (e.g., $item) can be embedded as-is; anything more complex, such as an expression that involves property access (e.g. $item.DocumentID), requires enclosing in $(...), the subexpression operator.
See this answer for an overview of string expansion (interpolation) in PowerShell.
