Help updating a simple if statement	Can't Post

I'm have very little knowledge of perl. I'm hoping someone can help me do a simple update to an if statement.

How can I add another user to this if statement? That is, only user1, user2 or the original author can edit.

Code

      # Only "user1" or the original author can edit. 
      if ( $regname ne "user1" && $author ne $regname )

Thank you for any assistance.

Instead of extending the if statement, my recommendation would be to crate a hash of the authorized users and then do a simple and efficient hash lookup.

Code

my %authorized_user = ( 
    'user1' => 1, 
    'user2' => 1, 
    'user3' => 1, 
); 
 
if ( ! $authorized_user{$regname} ) {

Thanks FishMonger. I can give that a try. However, where it is a large file, I would feel a bit more comfortable with extending the if statements that I need to update (add another user to each statement). Is that method possible?

I think FishMonger's proposal really makes sense, as it make it far easier to authorize again new users in the future.

But if you insist on keeping the existing syntax, you can do simply this:

Code

if ( $regname ne "user1" && $regname ne $author  && $regname ne "user2" )
