You should make sure the regex matches before using captured values: 
if (m{^(.*)/(tp_\w+)}i) {
    my ( $pathPrefix, $tpname ) = ( $1 ? ( $1, $2 ) : ( '.', $_ ) );
    # etc...
}

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
