elseif not being recognized – Variable not being assigned correct value

I have written a small script that checks the HostName in a URL for a sharepoint Site Collection and then gives a variable a value based on that HostName but the elseif in the script is not working:

$sites = Get-SPSite https://contoso.domain.cs/sites/sc 
$Logo = $null

if ($sites.HostName -eq "contoso.domain.cs" -or "contoso1.domain.cs" -or "contoso2.domain.cs") 
{
    $Logo = "/path/to/logo.jpg"
}
elseif ($sites.HostName -eq "contosoq.domain.cs" -or "contoso1q.domain.cs" -or "contoso2q.domain.cs") 
{
    $Logo = "/path/to/logo2.jpg"
}
elseif ($sites.HostName -eq "contoso3q.domain.cs") 
{
    $Logo = "/path/to/logo3.jpg"
}
else {}

The Variable $Logo is always getting the first value "/path/to/logo.jpg" even when the hostname is not equal to "contoso.domain.cs" or "contoso1.domain.cs" or "contoso2.domain.cs"

please help me if you see the error im making. thank you!

>Solution :

You need to alter the way you check the conditions. The entire expression to be evaluated must be repeated after each -or.

For example:

if ($sites.HostName -eq "contoso.domain.cs" -or "contoso1.domain.cs" -or "contoso2.domain.cs")

Should be changed to this:

if ($sites.HostName -eq "contoso.domain.cs" -or $sites.HostName -eq "contoso1.domain.cs" -or $sites.HostName -eq "contoso2.domain.cs")

Or you could do it this way:

if ($sites.HostName -in ("contoso.domain.cs", "contoso1.domain.cs", "contoso2.domain.cs"))
