How to show only Read-Host value from a text file array? - arrays

Question

I have a text file array JobTitle.txt which looks like this:
Sales Co-Worker, TSALES, TSALSK
Business Navigator, BNOM, BNOMD
And I wanted to write a code that would read the user's input and present the second and the third value from the same line. Here's what I wrote:
$jobtitledb = Get-Content C:\Users\Username\Desktop\Scripts\JobTitle.txt
$jobtitleinput = Read-Host 'Input the job title'
foreach ($data in $jobtitledb) {
$jobtitleinput, $basic, $extended = $data -split ','
Write-Host "Basic template is: "$basic
Write-Host "Extended template is: "$extended
}
I can't seem to figure out how to make it return desired line only. For clarification, when I input Sales Co-Worker I want the program to return:
Basic template is: TSALES
Extended template is: TSALSK

Answer 1

You just need an if statement that checks to make sure your input was the same as the jobtitle its reading in on each line.
$jobtitledb = Get-Content C:\Users\Username\Desktop\Scripts\JobTitle.txt
$jobtitleinput = Read-Host 'Input the job title'
foreach($data in $jobtitledb) {
$jobtitle, $basic, $extended = $data -split ','
If ($jobtitle -eq $jobtitleinput) {
Write-host "Basic template is: "$basic
Write-host "Extended template is: "$extended
}
}
Also I think when you were reading each line you were assigning the jobtitle to the same variable as the user input, so you should change that as well. Above code should work.

Here's an annotated script that should fix your problem. It's mostly the same as the original except where I changed it to store the job tile from the record in $jobtitle instead of $jobtitleinput and added an if statement. Also added a $jobnotfound variable and code to print the appropriate message
$jobtitledb = Get-Content C:\Users\Username\Desktop\Scripts\JobTitle.txt
$jobtitleinput = Read-Host 'Input the job title'
$jobnotfound = $ftrue
foreach($data in $jobtitledb)
{
# Store the job title from the record in $jobtitle instead of
# overwriting $inputjobtitle
$jobtitle, $basic, $extended = $data -split ','
# check the $jobtitle from record against the $jobtitleinput
if ($jobtitle -match $jobinputtitle)
{
Write-host "Basic template is: "$basic
Write-host "Extended template is: "$extended
$jobnotfound = $false
break
}
}
if ($jobnotfound)
{
Write-Host "No job matching '$jobinputtitle' was found."
}

Answer 3

I added an "else" statement, else { Write-Host 'Given job title does
not exist' } But it runs once for each line. How to make it return
only 1 line of "Given job title does not exist"?
I can't post comments yet, however you should just be able to use break within your else statement to exit the foreach loop.
---------- Edit ----------
The following should provide the desired output.
$jobtitledb = Get-Content C:\Users\Username\Desktop\Scripts\JobTitle.txt
$jobtitleinput = Read-Host 'Input the job title'
$found = $false
foreach($data in $jobtitledb)
{
$jobtitle, $basic, $extended = $data -split ','
If ($jobtitle -eq $jobtitleinput) {
Write-host "Basic template is: "$basic
Write-host "Extended template is: "$extended
$found = $true
break
}
}
if(!$found)
{
Write-Host "Given job title does not exist"
}
